Looking at the stock hard fuel lines in the Sprinter for the 4AC(feed, return and breather), they look pretty thin and pathetic, are these up to the job of supplying adequate fuel to a 4AGTE? Has anyone known of any problems with fuel supply reusing the stock lines?
I'll be running twin Bosch motorsport fuel pumps and an external surge tank to provide the fuel, it would be handy to be able to reuse the stock fuel lines which are already routed nice and neat.
yep they are definatly to small, they wont feed enough fuel to run a 4age properly even with out a turbo.
you can use the original feeder as the new return, and put in a whole new feeder line, cant remember the internal diameter we have used but go to global auto spares or something they seem to be pretty clued up on that sort of stuff.
and make sure its EFI hose,
Cheers guys - thats good to know before I start hooking everything back up!
I disagree with the statement above. I run a ZE at 110rwkw through stock lines. That's using a single VL/Camira EFI pump.
It depends what power you are shooting for. If you're going all out it might not be a bad idea to save any problems down the track.

JDM come factory with 8mm feed, and 6mm return...
jsut another reason for people to BUY MY CAR!! lol...
Will eventually be looking for around the 150-160+ kw atw mark so I think I'll upgrade them now whilst I have the chance.
Do ya's reckon it would be best to route some new hardlines - or just get some good quality flexible fuel hose from the pumps? I'm thinking the hard lines would be neater and then just connect flexible hose at the engine bay?
..i'll buy your fuel lines off you!
Definitely run hard lines. More work to start with, but a better solution.
I should be fairly easy to run them straight down the side of the driver's chassis rail. ADM lines snake back and forth over the transmission tunnel just to give you the shits.

I bought the line off an AE82 twin cam new from Toyota years ago very cheaply and bent it up to suit the floor pan which is a prick of a job. At least it has the correct fittings each end if using a factory pump and filter.
If I was doing it now, I would cut the fittings off each end of the fuel line of an EFI Toyota at the wreckers (pickapart is full of EFI Camry's) and buy a length of 8mm pipe and make one up to suit.

yeh no worries... come grab them.. $12 000 and they are yours!
gday fellas, just curious where you would actually buy fuel line and the fittings etc from? and how do you install it (ie bend it around corners) without kinking it?
