Default My Propane System Install, 1996 Dodge Cummins

I said I would show everyone, so here it is! First of all, Stodg73 found a tank for me (that was full too!) for $50. Then member Princeton Jake was selling his propane injection system for $200 (minus tank) so I bought it. I mounted the tank in the bed of my truck (sorry no pic of it), ran one hose from the tank which had a solenoid valve and pressure regulator to the variable flow regulator. I decided to remote mount the flow reg just so I would only need to run one hose from the tank. I got a little "creative" with the point of injection into the intake. I ran a piece of 3/8" copper to a point where the propane would be injected into the air flow to ensure the gas was completely mixed with the air. The second picture shows what I did. I did take the intake horn off the truck so I could drill and tap the intake for a boost supply to the flow regulator (that was the easiest way to get a boost supply). I also put a toggle switch in the cab, so if need be, I can turn off the propane if needed. After that it was just a matter of fine tuning until I got it where I wanted. I have it set to come on at about 2 psi boost and hopefully enough flow to help with mileage. I was impressed with how much more power is available with propane. At first when the propane came on with about 1/4 throttle the boost would go up to 25+ psi!

Question...

How much pressure are you feeding from the propane bottle? (Regulated to what?)

The tank regulator is set to about 45 psig. That was where it was set when I got it, the MFG'r says 40 psig.

The pressure from the tank to the first regulator should be about 150psi, then whatever the regulator brings it down to.

My systems regulator brings the pressure down to about 1.5-2 psi, when injected into the intake.

Tom I'm really curious on how the propane injection turns out for you. Also I'm curious what your fuel bill and MPG is like (including the proane usage in the calculation).

You aren't the only one!!It will be a few weeks before I find out. Right now I am only working about 10 miles from home.

How does it inject air that is lower than boost pressure? I would think the boost would shove the propane back in the line.

It is injected before the turbo, so there is only vacuum to be pulling the propane and air into the turbo.

Looky here ISX... MnTom installed a copper tube in the BHAF to inject the propane right at the compressor wheel.

I don't know if making the tube that long was really necessary or not, but I figured it wouldn't hurt. In my mind it was better than just dumping it into the filter.
