I'm cool with all the electonics, loom etc, but was wondering how people go about the fuel lines when converting to efi.

The is obviously already a fuel retun and supply. The meteing head, fuel accumalator and pressure reg get binned. Where do people move the fuel filter too, and is it the same one used? What sort of connectors and hosing is used to feed the fuel rail?

Cheers

 

I'm using Aeroquip on my fuel system, and I'm using a Skyline R32 fuel filter which is mounted under the air filter, almost. Christiano is using the original Bosch one so it can be done.

 

i fitted a frst lump to my escort and just joined the fuel pipe after the original filter to the fuel rail 1 as supply and the return was as it was in k-jet

i just bung'd it together tho

keeping the std filter and accumulator cant do any harm

 

its in there somewhere

 

Thats a bit of a hanibal lecter type butcherous approach to fuel lines though!!

 

worked dint it

 

Rick mate

Find yourself an EFI XR3i.............

I have EFI XR3i fuel lines kicking about

 

And just one question to ask related to this thread......will keeping the accumulator cause any problems on EFI?

 

didnt for me

 

I just wondered because i know the accumulator and pressure regulator on KE are matched for the closing pressures when you switch off.

Be good to keep it aswell will help with surging

 

I kept my fuel filter in the same place and my accumulator when I converted mine.

I robbed the fuel filter to fuel rail pipe from an EFi Orion and it all fits fine

 

I'm liking the inline pressure gauge, where did you get that and how much?

 

u don’t need to use the accumulator on the efi set up as it only design for an rst i got rid of my mk4 fuel filter with the banjo bolts and gone for the mk5-6 escort fuel pipes-lines as they are push on and off much neater - easier then an 19 mm bolt which they don’t make any more.

 

I know you don't have to use the accumulator but mine being under the rear of the car i really can't be hassled to source new fuel lines, and it can only help with fuel surging when the fuel is running low, thats its purpose? I would like to run the MK5 filter but where do u get the lines made up? Braided ones are dinlo money

 

well when u do the efi convsion u by pass the accumulator and take it out all toghther i know on the mk3 it sits at the back can u not by pass the fuel lines? i sure u can do it

 

Yeah there is ways, but that invloves finding a MK4 fuel line, then u have to start turning the pump around etc etc, plus the fact i just changed mine and its all been sprayed pretty metallic blue etc etc and stainless screws

I'll try leaving it on and if it causes problems then i'll remove it

 

I left mine on there purely cos I couldn't be arsed to take it out and find new lines etc lol

safechav got it off ebay mate, Ł30

cheers

One thing i just copied off the listing though:

The gauge is designed for testing the fuel pressure of fuel injection type systems not carburettors & not to be fitted permanently.

 

Good thread people - keep it up

Andy - the accumalator is therte to smooth the pulses from the fuel pump. As the KE is a constant injection system it needs a smooth supply of fuel to it. The pulsed electornic injector by nature dampens out any pressure changes. It's the swirl pot in any Injected fuel tank which prevents fuel surge

BTW - i know where to plumb things, just want advise on the practical method to do it. Aeroquip will prob happen, but i'd like to get it running via less exotic methods first

 

Im very tempted to keep it cos i am a bit of a run it into the red type Like to keep the weight down

If you want to get it running on the cheap to start with, then the MK4 EFI lines is what you want

Fuel filter uses the same bracket, but mounts on the inner chassis rail

 

safechav yeah I know mate but I put a thread up and most people said under the bonnet permanently would be fine, I've had mine in there for a while now and had no probs or leaks at all...

 

Fair enough Just checking

 

How much better and easier is that

 

pics? Are these lines flexible? How would i join them to existing lines?

 

The metal lines on the car are the same connection as the fuel filter etc.

 

I still have my accumulator

 

Accumulator stays, do you think my car will be as rapid as yours then

 

Probably not mate ................. It hasn't worked for Christian

 

PMSL ooooooooooooooooo, bitch fight coming up i reckon

 

Heeere fishy fishy fishy...........






......

 

***Waiting in anticipation***

 

lol, Tony - why did u keep ur accumalator - is it in the std position?

 

WHAT?! No nibbles???


I better put some groundbait out so the scent is in the water















I kept it for a number of reasons. One of which is that it cannot do any harm by being there , and as I did a blinding job of spraying it myself I thought it should be used. Also by keeping it, I get to use 2 more Aeroquip fittings....


Mmmmmmmmmmmmmmmm



Oh and yes, it's in the standard place.

 

So there was no practical reason for keepint then, just because your a tart and you have a bit of a fetish with aeroquip fittings yeah???

Mine is sprayed all nice blue aswell hence why i want it to stay, matches the fuel tank.....



Note the performence enhancing green plastic bag mod to the exhaust.....

 

Seeing as we are posting pictures....







I have a couple of mine

 

Tony Turbo: That is rather spanking, i suppose Aeroquip fittings are nice, shame MK4 master cylinders are so un-blingable and nasty

 

I think you can get chrome one's ?

 

Yea i was going to get one smoothed and chromed, but ching ching ching. Don't think ive ever seen one though has to look better than a standard one.

 

just think of this time u save when changeing ur fuel filter push on and off

 

You couldn't get one chromed because there is rubber and springs etc inside, it would melt. That's why I painted mine rather than get it powder coated with everything else.
