Fuel pumps and swirl pots

[Greenie]

Hi,

i need to fit a electric fuel pump and swirl pot into my 2.0 capri.

ive been told i need a lift pump to a swirl pot then a high preesure pump to the engine, can anyone who knows about this, give me some links or advice on what to buy and how to fit it all,

where to buy from and what new fuel lines i should buy would also be good.

thanks

Are you planning on running fuel injection or carbs?

What will you be using the car for - trackdays, race, or road use only?

click that link mate, should be helpfull
Go to JJC race and rally or just search Sytec injection pump on ebay to get the bits.

thanks for replys,

im going to be running an injected 24valve cosworth v6.

i do hope to take it on a track but it wont be a track based car just for tyre smoking fun.

I messaged JJC on ebay a few days ago they said they had most things to help me but wanted to get other advice

this is what im planning

the diagram is correct

.....have you got to run two pumps?.....could the low pressure lift pump be '' bumped '' ?

[exboyracer]

If the swirl pot is lower than the tank outlet you could possibly gravity feed from the bottom of the tank to the swirl pot, but it probably isn't a great idea.

.....I am getting old.....keep forgetting advice previously given...............bear with me.......

[Greenie]

thankd for the help,

next question is what type and where should i buy some fuel lines from, i dont want anythign special, just standard high pressure lines to do the whole car,

thanks

[caprimentle]

i'll be using 8mm micro bore copper for my capper, cheap enough, nice to work with, and tonnes of fittings for it available.

[exboyracer]

As above

[Greenie]

excellent will look into it.

is this the stuff?

ive got a brake pipe flaring kit, could i just flare the end and then push over some new high pressure pipe and tighten with a jubilee clip?

thanks

you could, better would be to solder an olive on the end of the pipe, then push the high pressure pipe over and clip it

[exboyracer]

Agree with Graham, I initially tries flaring the pipe but it made it almost impossible to push the fuel hose on.

Dont forget the pre and post injection pump filters mate.

diagram is correct.
your fuel pumps should be gravity fed also, this way there is always a mass of fuel on the back of the pump, which will reduce cavitation problems - especially if using efi pumps.
also from swirl pot to your secondary pump, this pipe (IN to pump) is generally larger diameter to help flow onto the back of the pump.

here is mine for example:

using a intank lift pump and bosch 044 secondary pump. note: larger diameter pipe into 044 pump. i have also pre filtered the swirl pot.


also, here is an interesting product that may be of use to some of you - solves 2 problems in one go

ok thanks,

i did see that 2 in 1 pump and swirl pot, looks interesting.

ive found the olives and pipe on ebay so will buy that as i need to do the pipes.

I am going to view a 2.8 tank later, which apparently is in good condition so may not need the swirl pot and double pump in the end anyway.

cheers for all the help

Paul.

I never went to see the capri tank, they wanted 120 quid for it and to do with swirl pump etc its about 25 for a swirl pot 50 for a high pressure pump and about 30 for a lift pump, so its cheap and i dont have to drop my tank out.

next question is i need to figure out how to power them.

i was to run them through a relay with a switch on the dash board so i can turn them off.

would these be ok to run them?

thanks again

thats a 24volt relay so dont think that will be any good.

[Graham]

you dont want a chane over relay, just a simple 4 pin relay

[Greenie]

Ok thanks.

If I get a 30 or 40 amp 12v 4 pin relays, wire a switch into the triggers that should be ok for each pump.

Going to order everything next week so need to check what I need.

Thanks.

[exboyracer]

The pumps will draw around 10-15 amps so the 30 amp relay is fine, use the 40 amp relay if you're running both pumps off one relay.
