Has anyone figured how to successfully run a fuel return line in a series 2 XJ6 using the original tanks? Other than swapping for series 3 tanks I'm stumped. I was going to buy a complete series 3 for the tanks but maybe there's an easier way.
Is your series 2 XJ6 fuel injected or running carbies?
I have never encountered an Australian delivered S2 XJ6 with fuel injection.
More information please
This may be too obvious, but here's how I re-ran my pressure line. Both press/return on my non-Corvette LT1 attach on left rear of engine and the S3 injected engine had the return on that side and press on right side. I intercepted the press line in the boot and ran a new line up to the brake booster area.
If you were running a carb and the original S2 had carb's, you will need a higher pressure fuel pump(s).
Same colour as my car! Yes it has a high pressure pump. Being a series 2 there is no fuel return infrastructure to the tanks at all. My conundrum is A, how to do the return from scratch without changing to series 3 tanks if its at all possible and B, can I do it using one tank. The more i think about it its going to be easier to just buy a series 3 and strip out the tanks and return architecture. I just blank off the holes for the immersed pumps.
Jeff, your series 2 carb tanks should have a plugged return port beside the outlet. It may be small but on an sbc I'd probably run 'em. I can take pics if needed.
Also, this will prob be helpful whichever way you go... https://www.welshent.com/Fitment/Dai...nk-Adapter-Kit
Sorry, I'm confused on who the OP is. E61 needing help and has a series 2 carb car with internal low pressure pumps correct?
