Re: Propane delivery on a 2.5L: Carb vs TBI vs MPI?
We always disconnect the computer, and use a second ignition module when do the propane thing with fuel injection.
A dual ignition system like CJ Dave has is perfect for such an application where you have to disable the computer when using propane.
I don't see why a carb wouldn't do the job, unless you have a problem with carbs....
A propane vehicle WILL NOT run upside down, unless you disable the safety gadgets.
There is a 'no oil pressure' kill (engine dies, propane stops), an inertia kill (when you hit something), and a 30 degree of tilt switch usually.
You may also want to use double safety shutoffs on the key operated switch. (Redundancy)
PS, a propane vehicle is exempt from most emissions testing in most states... But only if the original gas tank is removed....
There are some very reasonably priced Compressed Natural Gas systems on the market right now, and most CNG is cheaper than LP.
Both are VERY corrosive.
