I'm considering a variation of the DIY setup that I've seen posted before.
I can get propane cheap. Less than half the price of diesel. I can get tanks cheap (certified even, I know a guy). Lock-offs are free or cheap - I should even have a couple that work already. Although, I might have issues running a vacuum lock-off.
Would there be any problem running a pressure switch, that references MAP, so the propane is off until about 5psi? (Or something like that) Then basically leaving my propane on permanently. I figure then it would take care of itself as long as I have propane, and the regulator doesn't go out of whack.
Which also leads me to ask, has anybody used something less hokey than a torch fuel regulator? They aren't really ment for that... I'd probably rather use a modified BBQ regulator over one of those. Or buy the correct one.
I think I should be able to pick up some fuel economy, and maybe a little lower EGTs. I'd probably use a 160L (45gal) tank, under the bed accross from the factory tank. Depending.
Thoughts? Just hypothetical right now. I'm too busy to work on this truck.
