i did a search on ebay for propane injecton and came up with a book in the search results for a homemade injection system, they say for about 100 bucks in parts not counting the cylinder. Has anyone tried or heard of this? would this void the factory warranty?
You might do a search on the web and or this forum for "propane injection" and check it out. I thought about it, but found out it is not a "catalyst" for diesel but rather fires at a different rate and that it can cause probelms if not carefully monitored and used.
If you have ANY engine problems and Ford even smells a hint of propane or the goods for delivery anywhere around your truck, they will certainly void any claim you make for warranty repairs on the drivetrain. Exhaust and intake mods are arguable, programmer tuners are borderline, inline fueling boxes are dangerous and propane is a plain old dealbreaker when it comes to trying to get free repairs from Ford. BUT, if you want the propane, pay the bucks and get a complete kit ready to bolt in, not something you have to "figure out". Have fun. Mat
