Alloy Fuel tank, Fia homologation?

**Enea** · 02-11-2018, 12:39

Hello, I'm Enea from Italy, first time I write, but i'v been reading a lot in the last couple years.

I (well my father actually) own a Ford escort mk2, with 2ltr pinto engine, the car is being rebuilt to suit FIA historic rally.

I need a fuel tank with foam inside, is there anybody who know if the grp4 fabrications alloy tank has any kind of certification? I need something like USA military "MIL-B-83054" or anti explosion "DSTOP”. I tried to ask Burton but they didn't answered yet.

I found that someone already asked, but it was 7 years ago, so I hope something changed.

Thanks, Enea.

Most companies that make alloy fuel tanks will supply either, baffled or foam filled fuel tanks. I would be very surprised if grp4 fabrications didn't make a foam filled tank.

ATL fuel cell tend to be the standard required ,expensive tho

Thanks for replying, I don't need ft3, ft5 or similar FIA standard, is enough to have USA military homologation or Dstop anti explosive, I was wondering if someone that have the foam filled alloy tank from gr4 fab can confirm if the foam is homologated.

i highly doubt the foam is homologated

that's what FIA ask for historic car

4.5.2 For all cars from Period F to I the tank is free but must be filled with safety foam conforming to MIL-MIL-B-83054 Military Specification (shielding material) or “DSTOP” anti-explosion systems.

I'm no expert about fuel tank foam, but to me it seem no-sense to sell a tank whitout the right type of foam (I mean, for FIA racing use is compulsory, and that tank is basically for racing).

Thank you all for the replies, I also sent a message to grp4 just to be sure, but it look right what Graham says.

Thanks again.

uk national event dont run to fia regs on a lot of items, so most tanks for sale over here will not be fia compliant

Or just ask historic rally sport (HRS), they have built several historic Escorts...

just ordered, when it will arrive I'll see if it has any kind of FIA standard, but I highly doubt, also because it's way too cheap, luckily I've got a plan B.
