Line goes in to the bottom from the fule pump which fills the surge tank, other line at the bottom goes to the fuel rail on the engine and then the top line comes back from the regulator as the return line...

Is that what you want to know Gav?

I guess no ones got any info ? the fuel set up for an efi setup is my question.. some guys are running retro fitted late model pumps in there original tanks, this seems to be the way to go instead of the surge tank.
Has anyone done this or have any thoughts?
The 2 pumps id imagine would be quite noisy under there on a surge tank application.

How does welding go onto an old tank with rust (without re zincing) down the track..

This is on a Supra TT but i used to run twin intank pumps with a single external to a surge tank.

On a built engine i think its always a good idea to run a surge tank, but that personal oppinion, a 1-2.5l tank can save alot of headaches and problem down the track

On my old car I ran a Bosch 044 from the original tank, fed to a return reg, reg feedto the injection rail, return line from injection rail to(other end to feed) a t-piece fed into the hose between the tank and fuel pump. Also had a breather line tapped into the fuel filler neck that ran to the air cleaner. Whilst this setup is not absolutely ideal, I never had a problem with it feeding a 420rwhp turbo'd 6 I had in my old ek wagon..... Not to mention no tank mods need that I couldn't do at home. Hope this helps

Yep, I remember that thread.
I've read a lot about this system and wish our state rules would allow me to run an induction set-up that is more efficient, more reliable and probably "greener" than the old carby set up.
The only "bad" thing I've read about the Powerjection system isthat some think the pump isn't that flash, although this does not seem to be an opinion shared by everyone.
Not sure if many people run retro fit efi in Oz yet but it does seems to be quite popular in the U.S.

I put a Commodore V6 in my old Wb Tonner
I grabbed a VN tank and used the sender/pickup, pump and swirl pot out of it..
Made up a plate and a backing flange cut a hole in the stock tonner tank and mounted the whole lot in.
Worked a treat as most stock stuff does.
Never starved for fuel..quiet...cheap..reliable etc etc
And the best bit, GM use these fuel pumps in most of their cars thru the 90's v8's, vettes and all..
