I have a 1995 F-700 with 7.0L propane engine from factory. i need to know what I have to do to switch it to burn gasoline. The truck runs great as it is but I can only go about 22 miles on a 20 lb. bottle. I know that because I ran out 3 times bringing it home the night I bought it. My gps system showed my route was 66 miles. also Will the high compression of this engine be a problem with regular gas ??

 

Why do you have a 20lb tank??? The main tank should be at least a 200lb tank? Is it missing? To convert it well you will need the entire EFI setup and a new fuel tank. The comp ratio of the engine is the same as gas.

 

I have a larger bottle that came with the truck. I didnt know if a carrburator could be put on it . did not know it was fuel injection. thanks

 

i have looked at system on truck seems to be impco 425 and the piece that mounts behind it has model b printed on it
