Are you on about the engine? or the fuel tank?

[philthepill_389]

there are two fuel lines feed and return

were do they connect to the injection system

0ne goes to the bottom of the reg (Feed OR Return)

and one goes to the back of the efi (Feed OR Return)

[mowgli]

well, that looks like an aftermarket manual pressure valve to me.
It is not standard.

[philthepill_389]

i know its not standard just askin were the fuel lines connect

thanks

[philthepill_389]

so can some one help me

[philthepill_389]

anyone please

thank you

The feed goes to the end of the rail.
The return comes from the regulator.

To fit that c**p fse valve you put one pipe to the end of the standard rail regulator, and the other from the fse to the fuel tank.
That top pipe is a vacuum pipe.

[philthepill_389]

so whats the spare metal pipe that comes out the back of the efi marked in green on the pic were dose that go and do i need to put a pipe on it thanks for the help so far

thanks

[Adam]

No idea mate.
Where about is it on the engine?

[philthepill_389]

its just on ther back of the efi directly above the petrol feed pipe its got me well confussed fitting engines is easy getting them running is hard lol

thanks

[Adam]

I see the problem now.
Somones removed the standard regulator.
It should look like this, with the return pipe on the right hand side(under the reg)

I would therefore block that pipe off, and put that fse valve to the silver pipe on top of the rail
