Reverting back to fuel from LPG

My Series 2 with a 350 runs 100% LPG. I want to go back to fuel and will need to install a new left hand fuel tank. I don’t intend to install a right hand tank due to cost and lack of need for extra capacity. If I run a Holley do I need to a return fuel line?

Does the Holley have a facility for a return line? I don’t think they do.

i suspect you are asking about a holley carb and not the holley EFI?
no return needed for a carb providing fuel pressure is correct. 4-6psi IIRC

Correct, no return line. If the fuel tank has a return fitting I’ll have to block it off. Thank you.

I guess the replacement tank will come with a return fitting and an outlet to run to the other tank. Both will have to be blocked off if I use a single tank. Thank you.

i have a set of xj6 series 1 tanks i’d probably sell. no fuel injection return

Thank you but the freight would be prohibitive to Australia. Cheers.
