Hi All,
 
I am converting a Mk2 2 litre Escort to turbo charged with modern EFI however wish to retain the standard under boot floor fuel tank.
 
The car will be a reliable quick street car. No track work.
I do not wish to cut large holes in the body shell.
 
Can anyone suggest best design and layout and placement for fuel pump/s, regulators, return lines etc?
 
Thanks!

 
 

Hi Peter. I've just been through this planning process myself. You'll need to put a lift pump under the boot floor somewhere (there's not much room!) because the pumps are designed to push the fuel. If they pull, they burn out.
Then you'll have the swirl pot and EFI pump in the boot which I think defeats the purpose of having a drop tank.
 
A customised factory drop tank with built in swirl pot can be done which would eliminate the need for a lift pump and keep everything out of sight under the floor.
 
I opted for a GRP4 fuel cell with pumps & pot in the boot because the tank popped up cheap and I found out that it's not really that much of a problem to get a mod plate for boot fuel systems

Here's my boot. Still a lot to do

Some more. I forgot to mention GRP4 now do their tanks in two styles one being injection that has a built in swirl pot

In SA any fuel pumps, fuel hoses, surgetanks in boot area etc can not be passed unless enclosed in a Vapor proof enclosure that is vented outside,accompanied by relevant engineers report of course.

Here's mine Peter. This is version 2, Commodore fuel pump assembly inside original tank. Works a treat.
 
Version 1 was original carby fuel pump feeding a swirl pot in the engine bay which then fed a bosch 910 pump mounted to the inner guard. The excess fuel went back to the swirl pot then back to the tank. It used the original plastic fuel lines to & from the tank. Worked well for about 6 years.
 

 
Cheers, Craig. 

My mate has EFI his 2L in his MK1 Panelvan. Looks quite straight forward but will have to ask how his is done.

Anyone used something like this

Thank you for your replies!
 
Why is a swirl pot/surge tank necessary for a street car?
 
Thanks.

It's necessary for any efi engine, as soon as fuel surges you get instant fuel pressure drop which causes instant lean out of your mixtures.

Cheers
