Naw you need CAT ET to perform the injection pressure tests, etc. The generic scan tools and software generally don't understand the HEUI system and special tests you can run.

3116 is a mechanical injection pump with the lift pump on the back of the head. 3126b and C7 have HEUI injection pumps with the lift pump driven off the back of the HEUI pump so the lines are going to be totally different length, etc. Not sure about fitting sizes but there's also a difference in...

The reference to a "fuel shutoff solenoid" makes me think that was all 3116 stuff. And the 3126/C7 have different fuel systems so may or may not be applicable. Electronic engines don't have shutoff solenoids. They just cut power to the injectors when the computer loses the ignition power signal.

Hhhmmm - pop into CAT ET and see what your injection oil pressure is doing. Assuming that's good I would check the lift pump fuel pressure.

I had the factory hoses copied by a local hose shop. Push-lok fittings work fine also. They are perfectly adequate for the pressures involved. Obviously the hose needs to handle diesel.

Have you replaced all your fuel lines yet? They will be rotten and could be sucking air.

Sounds like a fueling issue to me.

I was taught to do peckerhead connections with bolt/nut/lockwashers and cambric tape, splicing tape, and finish with electrical tape. Never had one rub through or come loose 🤷‍♂️

It's a $400 Chinese 24v mini-split. Works well for what it is - blows 40 degree air a decent rate. I just don't think it would work as good or integrate as well as the Red Dot. I should have said "defog" - the air drying for defrost becomes less necessary the lower you go in temperature - so...

I've got the Red Dot gen 2 system in my truck and it works great. I also have a 24v DC unit in the habitat and it...... blows cold air. Admittedly the habitat is a dark color and aluminum - the awnings help and I've got real big windows to assist with ventilation. The reality is it's really only...
