hi would anyone know how to set up the fueling system for a 2ltr xe into a chevette, iv been told i need to run a certain pressure in my fuel lines in order to run the engine. is this true? if so what do i do with the standard petrol tank to make it compatable with the engine? thanks...

I think you'll need at least 30psi for fuel injection, but I'm not familiar with what pressure the system on the XE runs at. I'm not sure, but I think you should be able to keep your existing tank running an external fuel pump... I stand to be corrected on this point though so please wait for a more definitive reply! How far along is the project? Sounds like it should really fly when done!  |

Youll need a supply line and a return line, both high pressure injection compatible. If you use the stock XE fuel pressure regulator the pressure will be set within the stock limits.
Are you using the stock ECU?
Cheers

yes I'm using the stock ecu and fuel pressure regulator, I'm welding the small rust i hav and werlding in some rear turrets next week hopefully, i have lowering springs, spax adjustables, 4 spoke revolutions and recaros to go in.

Any bosch external tank type pump should suffice. The regulator will control the pressure.
As said you will need a return line into the tank and you will need fuel pipe suitable for fuel injection for teh supply and the return. You might need another breater on the tank to stop it vacuuming as well.

What some people do is use a normal low-pressure pump to feed a swirl pot / tank in the boot and then run the high-pressure pump from that. Advantages are that you get less chance of fuel starvation on the bends or breather problems and you don't have to try and fit a return line to your original tank, which can be tricky, or if you try to weld something in, quite explodey.
Don't know what the original tank is like though, might be easy to modify.

so would i use the original tank and have a swirl pot with a pump attached,, but what pump do i get? should i get a facet pump raited at 3o psi? or what ever the system runs at?

Where is the tank located at? I know saloons are behind the rear seats. I am guessing hatches are beneath the floor. If you run it with a swirl pot you will have to have two fuel pumps. The setup will basically be. Tank=>Low pressure pump (facet type) => Swirl Pot => High pressure pump (Bosch Type)=>Injector rail=> regulator=> return to tank The swirl pot acts as a reserve amount of fuel so there are no surge issues as PaulWakely says. If the tank has good baffles around the pickup its not a problem however most older tanks are not well baffled and you will probably have problems especially if the tank is running low. |

thanks very much mate you seem to know your stuff, do you have a redtop in your escort? if thats yours in your avatar. if so i guess you used a ford gearbox because I'm having trouble getting my manta gearbox onto my engine i think its just because my flywheel is too thick can i use a lighter one from a cavalier 1.6 or something?

No, just a tired pinto until it gets rebuilt. Not 100% sure but I would have thought the manta flywheel would be the one to go for.
I am sure some one will be along soon to tell you what flywheel, clutch plate bearing setup you need.

2 quick fuel injection questions:
how big does the swirl pot need to be? as I'm pobably gonna get a bit of big tube and mig weld plates to the end to make mine, as i cnat relay afford £50, and are all fuel injection systems roughly the same pressure, as i have a honda CRX mk1 electric fuel pump (MPI) but want to check its up to the job for my punto sporting (also mpi) system.
Cheers in advance.
