Complete system ... whats it worth ??
 

I have a 1995 F-700 with 7.0 L running on propane, I am switching to gasoline. What is this propane system worth ? main throttle body looking thing has 425 stamped on it .[ IMPCO ??] the piece directly behind that is stamped MODEL B .. This is a good running system just not working out for me. Let me know if anybody would be interested in it ..

I picked up a spare for my Bronco for 100 bucks with a half full tank ..it is worth much more ..but ,,so what is the problem with your unit ?? power ?? poor mileage ..or no one that can set it up to work right ??mine was fine tuned and I am very happy with it..it has been on my truck 20 years ...and it is an impco 425 ..I also have a duel mix unit that I am gonna try ..

nothing wrong with it , truck ran great just not what i wanted , it limits mileage here there is no where to refuel

Now the light's are on ..with all the advantages ,I wonder why it is such a pain to find it ..offer it for 600 and see what happens ,that's about half of new ,so it makes it worth while to someone looking for a working unit..
