this is a great site for the ngv lover,very interesting reading.i own 4 bi-fuel trucks,2 chevys 96 and a 99 fullsize,and a 96 ranger,and a 95 dakota,not real proud about those 2.lol,but they run cheap.i also have a gas well at my property that i drilled in 06,and fill these trucks using a fuelmaker fm4,that i purchased after the poor old c3 timed out.i am putting together a ingersol rand ng compressor package that will be powered by a 1.8 vw industrial engine that is set up to run on ng,and will use it hopefully to fill a cascade for a quick fill.thats the dream anyway.lol. great site,great information,proud to be a member,because we all know its the way to go.dave.
