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

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
