Didn't plug the truck in last night. +22 out this morning and it started, ran for a short time, then died, like it's gelled. I must be getting a lot of condensation, or some pretty crappy fuel. I already quit using the place I was having trouble with that was only mixing 70/30 #2/#1.

 

If it is gelled fuel, you could use a diesel or kerosene torpedo heater to help "un gel" it. That. or use a heat gun.

After it's running, go get some anti gelling additive.

 

Is that 22 above or below 0 if its 22 above fuel shouldn't gel I live in Texas it's 18 here a few times and I haven't had any problems starting my 92 and my grid heater isn't working sounds like your sucking air

 

If its 22 below might be a gelling problem

 

If its sucking air you can pressure up your fuel tank and look for a wet spot sounds stupid but it works

 

My son pulled in with his 24V second gen. Temp went to -20 overnight. Truck started and died, fuel pressure 0. That was blended fuel, no additives, electric fuel pump.

I said "filter time." He said "Naw, it ran good with good fuel pressure coming in." I made him go get a filter and put it in. That was the problem.

What causes fuel flow problems in cold weather is solid crystals or globules of paraffin. Lighter fuel has less of it. The anti gel additives make the crystals smaller.

When a filter is dirty, the passages through it are smaller. Even the smaller particles of paraffin can't get through, and stop it up. Change the filter and the fuel flows.

Blended fuel should be good to -20F. With power service or equivalent, should be good to -40F. That assumes the filter is maintained.

The other possibility, a suction air leak, would be amplified by the increased viscosity of cold fuel. Also, any rubber parts get stiff and shrink in the cold, maybe causing leaks. (pump diaphragm, rubber fuel lines, etc.)

 

I'm hoping a filter will do it. Luckily I got this Amigo to drive now. Between the electric bill, and the dog needing to go to the vet's, it has to wait another week. Going to try dumping the filter out and see if that helps. Tried but got nothing out the bleeder a couple days ago when it was almost 60 out.

Yes, that's +22, not -22. And I have been running power service all winter.

Last fuel I got was in North Platte, they have a high water table up there, and the place was right along the S Platte, stopped there because of the Subway. Never had trouble there before but that was a year and a half ago I fueled there a few times.

 

When it dies, crack the number one fuel line "17mm" and see if air comes out. If so you might need to chase the fuel lines and see where it's sucking air in. Mine keeps doing this, I still have yet to figure this out.
