Auto-LPG Conversion Thread

[ghosthunter]

Hey Guys,

I'm thinking of converting my 1998 Ford Expedition to LPG. With the number of conversion kits and suppliers available, I'm pretty confused and am looking for some advice as to which kit I should use and where I should have it done. I don't really understand the differences between all the suppliers in the market. Which supplier would you guys recommend for Expeditions and why?

if you don't mind costs, Macro comes to mind. Greenfuel also has done a number of big Fords including first gen Ford XPs and costs less than Macro. Alpgas also has done XPs but I haven't personally seen the work. SKN also has done XPs but there seems to be certain details that I would prefer not to recommend them though.

Also, after testing for some time (maybe a month), I plan to sell my Exped and get a newer one (2003-2006) then transfer the kit there. Is that possible? The reason I wanna stick to an Exped is because of the ride but at the same time, gas prices are pretty ridiculous already.

Although technically possible, it would be a waste of time and labor to install the LPG kit into one vehicle and then transfer it to another one because certain parts will be un-reusable like the LPG feed tubing, electrical wiring, etc. Converting an XP takes about 3 to 4 days as compared to 1 to 2 days for a compact sedan. That shows how much extra work it takes to do an XP.

If you really are planning to get a newer XP, it would be best to sell the old XP and directly install the LPG kit to the new XP.

Although fuel prices today is ridiculous, the XP's fuel consumption is really terrible (petrol or LPG) and I do wonder why you prefer to drive the XP when a big sedan (like a Camry) would do the same with lower fuel consumption.

BTW, most auto-lpg conversion shops only use 60L tanks as their largest size ... this would mean a cut-down on your XP's maximum range when compared to the original 100L petrol fuel tank.
