Interesting, I wonder how hard it is to pass.

As for home fueling $1,800 to have it installed “no they want let me do it myself” $46 a month charge plus gas so that’s not happening. When I called around to some of the gas places I was told no way am I fueling a car so that kills it for now. Now for LPG its every where called five places all said they would be happy to fuel me up anytime and there is even three 24hour LP stations around town.

$1800+ you need to be constantly rebuilding the darn thing. Personally I have been tempted to import and Adsorbed NG tank.

Honestly most LP conversions have little if anything done to the motor, now if you want to up the compression to 22:1 thats different,
if you run a slightly older diesel you don't even need ECU mods or tuning.
Just fraction a bit into the intake and voila
