Bullydog Propane Tank

Can a Bullydog Propane tank be used as a fuel tank for a propane conversion? I am assuming it uses a liquid line like is needed for running a gas engine on propane?

I am trying to find a used tank and want to know if the Bullydog tanks are a viable option for my propane converted Bronco.

Um, not sure if your engine was a gasoline one or diesel. If gasoline, put this in another forum.
As far as I can tell, you want to run vapor.
Thing is, unlike running a gasoline engine, you're only adding a /little/ propane to your diesel. Add too much and you get pinging, so you have to keep the ratio low.

If you've got a vapor valve(the fill valve might work?), that's best.
Alternately, if you find one, a small vaporizer unit like they use on a forklift/car would do the trick.

P.S, two things:
1. It's possible to make an IDI /run/ entirely on propane vapor... though very poorly, due to no timing control(it burns when you manage to get a good ratio and heat).
2. You need to have enough air to burn the propane; you'll only get extra power out of the propane if you've got a lean burn already. This means a turbo, or bigger turbo.

best to use a boost switch to active the propane only when needed, and when the engine will benefit, at load, and it will cut out when boost drops, cruse.
