Wierd application, hypothetical question.

[justin ivan]

Like I said, I don't know that much about propane on diesels just know that 
on turbos it makes a hell of a difference.
Might be able to us an adjutable wastegae controll modified for your 
purposes. I guess to reall be able to help you (even if it were solenoid 
operated) it would help if you had an idea of the stroke vs force required 
for the pump.
