    HOW TO FIT A ZETEC - Part 1 - Fuel System

    Heres the first in a series to help anyone considering the Zetec Upgrade, I have compiled these posts from mainly information off the forums, so a big thanks to everyone who has shared thier data with us.
    I will be adding and updating these posts as we find out more so keep an eye on the edited date at the bottom of the post and reread it for the latest information.


    Fuel System:
    Carbs or Injection:
    The choice to use Carbs or Injection is an inportant one, think about the following:

    1) Type of Fuel system (High or Low pressure).
    High Pressure will need as a minimum:
    :: High Pressure Pump
    :: EFI Filter
    :: High Pressure Fuel Lines, including a return to the tank
    :: Fuel Pressure Regulator
    :: Fuel Rail for the Injectors
    :: Injectors
    :: An injector boss (in the manifold or Throttle Bodies)
    :: Throttle Bodies
    :: Fuel ECU

    Where as a low pressure system needs a Red Top Pump and a Filter King Regulator.

    2) ECU Required (Ignition Only or Full EMS).
    Ignition Only ECUs are quite cheap and readily found secondhand circa £150, Full Ignition and Fuel however will cost more luckily many new ones are around costing £350 upwards.


    Inlet Manifold:
    A DCOE flanged manifold will take DCOE carbs like webbers of Delortos, you can also fine Throttle Bodies designed to replace carbs with this flange on them, they must have an injector mount in the throttle bodies.


    DCOE CARBURETORS


    DCOE TYPE THROTTLE BODIES

    A good way of getting an impressive setup is like Richard Chambers has done, an ST170 inlet manifold, fuel rail and rubbers are used to mount Motorbike Throttle Bodies:


    FOCUS ST170 INLET SYSTEM


    MOTORBIKE THROTTLE BODIES


    CHECKING THE SPACING

    The motorbike throttlebodies come in a variaty of sizes 38mm being the norm. A few modifications will be needed to make them fit:

    1) The bore spacing will need enlarging, it is important to add here some motorbike throttle bodies are cast togethter so the best ones to get are off the 2000-2004 modles of GSZR600 and GSXR750 or other ones that can be split. Spacers can be made to go between the indivudial bodies to equel them out to match the ST170's manifold's spacing. The original fuel rail and injectors will need to be removed and the injector holes plugged up a small core plug will suffice.

    2) The ST170 Fule rail will need to be modified to take a fuel pressure regulator as the Focus pumps are pressure sensing (CVH EFI one will do) and a return outlet added to the pipe, as a not the thing on the centre of the pipe is to dapen the pulses in the fuel rail and can be left in place.

    Tank, Pump and Filter
    If your not going to use Injection then the standard tank need no consideration.
    If you are turning to Injection then your quite lucky as the tall tank in the Escort has a fairly good design for a fuel injection system, I know many people who have simply fitted a pump and filter in line with the outlet (enlarged), as a general rule keep the tank above a 1/4 full. Its best to thorougly clean the tank out to get free of any debris before swapping to EFI, a new union can be fitted in the bottom the OD (Outside Diameter) of the outlet shoud equal the OD of the new pump so a simple rubber fuel pipe can be used to connect them. A return is required for the fuel thats bled off by the regulator, the RS Series had a return which can be reused, if you dont have one I suggest removing the level sensor and fitting one to it.

    Any Fuel Injection Pump should do a sierra one is a good bet, it should be fed with a good quality wire and switch via a relay controlled from the ECU.


    SIERRA FUEL PUMP

    A few choices for filter, if your using a sierra pump then use the whole sierra cradle and filter the pipes and connectors will then all fit. You may however consider using a filter with push on fitting so a jubille can be used to retain the pipe.
    A word of warning though EFi fuel pressures are near 50PSI and when a leak is present it hightly dangerous so care and attention should be excersised when designing the layout of the systems.


    Notes
    A friend of mine is using a XR2 twin choke and manifold on his 1.8 Zetec, he said he had the redrill the head and get the carb set up on the rollers which cost £65 but it runs very well.

    Re: HOW TO FIT A ZETEC - Fuel System

    nice start... presumably the advantages of the high pressure/injection setup is more presice control of fuelling as carbs are going to be a compromise for most of the rev range?

    You do lose the sound though

    Throttle bodies sound similar to twin carbs its just they just back fire and run rough on over run

    hey clint great article just whats needed imo.

    could you possibly tell me though what fuel pump your mate is using with his XR2 carb? im using a 32/36 DGAV from a x/flow escort and it would help me and maybe others thinking of the same induction.

    cheers

    Are the ST170 injectors the usual side feed? If so it will limit upgrades as not many companies make/use these.

    mines a similar question but as im looking at doing it to a mk4 escort could i use an orion 16i /xr3i MFI tank & pump or would this flood the carb ??? i was going to wire it up to the ignition or may be a switch (as it can double as an immobilizer as well !!!) this is going to use an xr2 carb to start with but mite get twin carbs would i need to change the pump if went down that route ? just want to know before i start doing this what im letting myself in for cheers

    I've seen it done in a magazine but can't for the life of me remember which one. If the inlet manifold fits (black top ones don't, think the silvertop Escort/Fiesta ones do) then the rest is just wiring. You would only get the 130bhp standard power from the 2 litre and it would run exactly like in a Mondeo i.e. a bit flat. I remember reading that everything plugs in but you can't fit the speed sensor although this aparently made no difference to the running.

    Car to engine wiring goes through one 12wire connector and not all are necessary to use. My engine ('97 Escort 1.8 115hp) connector is/was:

    1. switched +12v (run & crank)
    2. fuel pump relay
    3. rpm signal
    4. empty, not used
    5. switched +12v (run)
    6. oil pressure light
    7. +12v continuous
    8. switched +12v (run)
    9. to diagnostic connector, not used
    10. A/C signal to ecu, not used
    11. A/C signal to ecu, grounded
    12. temp gauge

    Also power steering pressure switch wires were connected together.

    Notice that this is only for this engine, others can be different, no guarantee!

    Re: HOW TO FIT A ZETEC - Part 1 - Fuel System

    hi guys, im just getting to the stage of starting to get all my bits together for my conversion. one thing im unsure of is the pressure the system works at. what kind of pressure we looking at between the pumps and the injectors? am retaining the original injectors and plenum chamber btw. just want to know for when i order the fuel lines, i had a stainless braided petrol hose, been told its good upto 10bar. that any good? cheers

    Around 3bar regulated (45psi) as a rule of thumb. Though give yourself a decent factor of safety. Fuel fire aint a fun day out!

    oh right! thought it would be higher, do the facets red tops not supply 5-7 bar? would these not suffice if the pressure is not that high?

    fair point alladdin! just checked up, ur bang on! it is psi indeed! so fair to say that a 10bar rated stainless braided hose would be sufficient for for the injector pumps, inc return ppipe??

    injection runs as stated about 4bar , make sure the hose really is rated at that tho, not just a pretty substitute.

    The pump off an injected sierra will see you right, dont forget a big filter prior to pump though. This should give you some kind of swirl pot 'constant fill' effect so the pump dont run dry. Anyone want to comment on that? I'm still building up so can't say from user experience. Keep the pump as low as possible. Good luck

    Re: HOW TO FIT A ZETEC - Part 1 - Fuel System

    thats an interesting point, so would it be fair to assume that by putting a large filter before the pump would remove the need for a swirl pot? already fittted a shaped alloy tank thinking i was putting a pinto in on carbs! great these last minute ideas! so, my plan was to fit a facet from pump to swirl pot, swirl pot to injector manifold to be supplied by a efi pump. so might be ok by substituting the facet and swirl pot with a big filter! the hose has come from pirtek on a speciall order, as they specialize in oil rather than petrol, but they guy did a phonecall to his supplier to confirm the pressure rating on the hose, and they say its rated at 10 bar, can only take their word for it! and a damn site cheaper than most places who sell the same thing on a different label!

    Re: HOW TO FIT A ZETEC - Part 1 - Fuel System

    hello,just wondered if you could help me out before my car goes up in smoke,its a mk1 escort fitted with a 2.0 litre black top zetec,its running on a bogg bros r1 bike carb conversion(or isnt at the moment) this has been a long job getting all the bits together .eventually got it running for a short spell during the xmas hols but it refuses to start now,just backfires eventually .it has a manual choke fitted which doesnt seem to make any difference.new to this carb set up before so i was wondering if anyone has come across this before?even backtracking now to double check everything but it makes no difference,checked timing belt and even bought r1 fuel pump but it makes no difference.it has a megajolt ecu which is running the pump and firing the plugs.any ideas would be great
    thanks

    since it was overfuelling ( you think) have you tried it with pump off ? im assuming bike carbs have some fuel in a bowl...

    will try it 2moro with pump disconnected,also going to do compression test just to make sure everythings ok,it ran for about 5mins over xmas but nothing doing now,just the backfiring -update you soon.swapped plug leads thinking it could be 180 out but still nothing-bags of spark may need a tow I think as the engine has been laid up for two years and bores have been oiled for all that time?clutching at straws now -wish i never went down this road but gone too far now to rip it all out and pinto it,thanks for the reply anyway.phoned bogg bros they told me it must be an ignition fault?who knows?

    I thought carbed R1s were gravity fed? You've not got an injection pump have you?
    A normal aftermarket carb type car pump with a regulator at about 4psi should be about right I think? Feel free to contest this opinion, its just that a mate was looking to do R1 into Smart car last month () and when we weighed it up one of the things on the 'needed' list was a pump, as the bike he had didnt have one.

    Re: HOW TO FIT A ZETEC - Part 1 - Fuel System

    hello,tried the original r1 fuel pump today,the pump runs until the float chambers are full then shuts off, i did have a facet on it originally with a pressure reg in-line turned down to 3.5 psi but it hasnt made any difference.its strange that it has run briefly but now refuses to start at all.going to do the compression test tomorrow incase theres a compression issue but other than that its a mystery.if it was a pinto engine i would say that the firing order was wrong but i have refitted the timing belt using all the locking pins,and run the plug leads from the correct post nos to the corresponding plugs -no difference.if the plugs are out you can see them all firing and there is definately fuel in the float chambers of all the carbs because i have cracked open the drains on all 4 and fuel comes out.thanks for the reply

    quickstart down carbs, no fuel pump. if it runs its fuel else may be spark BUT if you have changed NOTHING since it ran then its not a setup issue. i have a coilpack if you want a spare to try ? i work in rhumney hov.

    update
    compression on all 4 cylinders good around 165-170 on all 4 pots.think i may have found the problem -its suddenly dawned on me that the air filter side of these bike carbs have 4 small alloy diffusers that screw through the air filter plate and into the carbs,they have small cut outs where the lower venturi jets are fitted and must be there for a purpose,these probably operate the diaphragms.I removed all 4 of these to replace the throttle cable so this has got to be it?find out tomorrow

    still no joy,really strange how this has happened now.if it hadnt run I would be ripping the head off but dont know what to check next?its the backfiring and popping from the carbs thats throwing me,tried fuel down the carbs,running with pump off,new plugs and new static coil? removing inlet manifold next and starting from scratch again -hope to find something soon.anybody come across this before?

    From what you've said so far I'd still go for the ignition timing being 180º out of phase.
    Don't forget that the dizzy only rotates once for every two revolutions of the crank.

    Make sure that that rotor arm is pointing to no.1 plug lead when no.1 cylinder is on the firing stroke (all 4 valves should be closed).

    Don't forget that the dizzy only rotates once for every two revolutions of the crank.

    The leads could still be out on the coil pack but zetecs do not have a dizzy

    I am getting ready to fit a 2L silver top in my wee 100e with the full EFi system. would be gratefull if you know which wires i dont need in the loom. I have everything wire and sensor plug wise. i have the full engine loom, full car loom, the wee key sensor ring and key and original ecu. I just lifted the engine complete with loom out of the mondeo without removing anything from the engine. wiring help would be great.

    Seriously - fuel pumps pull large amps, bigger than the ECU can cope with so best supply via a relay that handles the heavy current!
