G'day guys,
just trying to get the petrol working on my tb42 in my maverick and i noticed that the fuel pump isn't wired up. my question is should it turn off when i switch to LPG or stay on. just trying to work out how to wire it up.
Thanks,
Calvin

obviously it sounds efi ? or is it custom ?

generally the fuel pump is kept running, just make sure you leave fuel in it other wise it will burn the pump out..

i have disconnected a few it doesnt really matter. some people say on / off..

just add a relay in the fuel pump wiring. activate the rlay off the petrol side of the lpg switch..

cheers :D

it should be off when runnning on gas. but you should run it on fuel for a bit every week or so to keep everything lubricated, and clean

LPG is way better off road thjan a carb.
If you have a huge power differance there might be a problem with the LPG system.

Wire it to only power up when on petrol, no point having it pumping away if not needed and also can be dangerous if a hose splits and fuel leaks.

Exactly right i have lost count of how many people have asked me why i run mine on lpg all have said to use petrol while 4x4ing, but in my case gas is more reliable than fuel cos its a gas not a liquid so there is no pickup :)

The only time petrol may be better is if you need every bit of HP say in a tractor pull comp
