Thread: Modification to dedicated LPG....

Hi, you will need a safety cut-out from your LPG fitter. Remove your petrol start switch system and wire in a plain change-over switch. Then you need the safety cut-out to stop the LPG from flowing on when you stall. If you are lazy you can prop open the AFM with a small bolt threaded through the side, holding the door open (you can remove it to regain petrol mode). A piece of 3" exhaust pipe works too. Also you can buy a VN-VS V6 commodore fuel pump and fit it , only around $80 trade, or second hand. Remember to clean out your old fuel if you do. Cheers

Thanks for the info! I just went down to the local mechanic and suggested this approach. He said that is a good plan and could do it for $150 and it will take a few hours. Cheers!

You shouldnt be going thru pumps like that, does the pump run continuously even when on gas ? If so you need to wire it so the pump has no power when you switch to gas.

Yep, the pump USED to run while using gas. I am having it run on dedicated LPG on friday so no more problems with pumps. Next will be a larger LPG tank for the trips away!

Thanks!

Personally i would keep it dual fuel and get it working properly so you get a better range with combined fuel, i've had 2 dual fuel rangies and could get about 800+ k's with both.
