Hi All,
Some of you may remember this thread before the server died.

I’m looking at removing gas from my patrol and put in the standard 95ltr back in the rear. I would like to keep my sub that is all ready under the drive side it’s about 50ltr, although keeping this at this stage is not high priority.

Looking for some info on how big this job is, I’ve heard if I’ve still got the fuel lines running to the back it shouldn’t be that hard.

the bigest part will be the wiring because when they put the gas on, part of the gas switch will kill the injector pulse or the fuel pump so that the fuel system is not running wile the gas system is running and if you go tugging at things and removing things willy nilly you may end up with a fuel system that doesnt work
the key is to have the patrol returned to factory not just made to work

in my holden wagon
my fuel pump keeps running while on gas
i need to always have fuel so pump doesnt run dry
this must be a different system to what you say

I did the Gas to strait petrol sway in a shorty a few years back . I'm not sure what issue's will come from your's being EFI . But as fare as putting the Tank, sender and crap back in it fairly easy .
you can just swap the EFI fuel pump back over to your main tank . and re-connect your fuel lines up . my Factory hard lines wernt cut/ changed at all .
if you want to keep the sub tank you'll just need to deside if you want to be able to switch between tank's or just fill your sub tank and then use a trancfer pump to fill your main tank ( this is the easyest / Cheepest way ) . otherwise you'll need an electronic valve to switch both the fuel intake and return line's over , and a second EFI pump ( I'm not sure if the EFI pumps are in the tank or not ) .
