Gas to LPG conversion?

Has anyone done any research on this? PRetty much you convert your gas truck to Liquid propane gas. It's supposed to be common in Canada and Europe. Altho not as much in Canada. I cannot find any "universal kits" or any kits for rangers. Any info for US conversion you could find would be helpful. I've been doin research a day or two on this because LPG is 1.47 a gallon here!

9:10 ratio of LPG to gas. So for a gallon of gas, you go 9/10 the distance on propane. It's not commonly done here, you mostly see it on forklifts and whatnot. It's supposed to be sorta popular in canada and popular in europe. Maybe John Griggs might know something. I have it figured out but I don't know about EFI, involving injection and computer.

look into industrial applications. I know they make a 2.3 that runs on propane and it is still fuel injected. Off hand I cannot think of any 4.0's that run on propane. If you had a chevy 4.3 it would be easy to do since most forklifts use it. Personally I don't think it would be cost effective when you look at all the parts you need and then the tune for the computer.

To name a few of the parts that you would need and I know I will leave a few out. This is if you used a carburetored motor.
lock off valve, vacuum or electric used to turn propane off
propane converter, to convert propane from liquid to vapor
propane tank
fuel lines (nonconductive)
cooling lines for converter
special carb. for propane
adapter for carb. to intake

I see by all our research you have an educated opinion. I didnt exactly say i wanna run my truck offa cold fusion.

Casfz1, I see it as the hardest part is to get it to be controlled by the engine. Maybe someone like the bamachips guy could flash you a program for 400 bucks or maybe more. But he might have to actually have the truck with him to work on that. As to hooking it up, its seriously not that expensive.. All you need is many of the regulaters and tools you can buy at your local propane store. Which we don't havae here heh, but what I mean is pretty much you're controlling the flow of hte propane since it pushes itself, unlike gas. Some of the online research i found saw them doing carbed vehicles for as little as 160 dollars.

Carbed though. I'm going to research LNG now though. Because it isn't a product of crude oil like Propane is. So it doesn't fluctuate the same..

I'm jus pretty worried about gas prices right now. It's pretty lame to hear gas is going to hit between 3 bucks an 5 bucks.

Aron, I work on propane trucks all day long I am a industrial truck mech. To answer you question on how to regulate the fuel that is what the converter is for they make them in different pressure setting depending on app. As for the tune I would think they would need the truck.
I will look tommrow at the 2.3 at work and see how they control the fuel on a injected truck.

Thanks man. That's interesting about the chevy 4.3 too. I'm also looking into LNG right now.

We converted our lift trucks to LNG back when ford was testing there natural gas cars and trucks and had nothing but problems with it went back to propane about 6 months later. I think it had something to do with the octane rating between the to but not sure.

I did some research on propane and the big problem with propane is it is a derivative of petroluem so unfortunately the price will rise.

BUT petroleum as AWESOME effects on mpg and power out of diesel1
