I own a 92 with pre-turbo 7.3 and 5-speed. I have heard alot about propane injection lately, but most systems seem to be for powerstrokes. If anyone knows of a good system for my truck, whether store-bought or homemade, any information you could give me would be a help.
Zigg has just what you are looking for, he built his own system and has been running it for quite a while with no problems. Check out his site, he has instruction on how to build your own system at home for very little cost.
