Where is everyone #5

Both likely culprits. Gauge was acting up earlier. Bouncing all over the place but settled down.

 

those sending units have been acting up since I drove Peterbilts made in the late 80s.

 

Neither had pressure when I opened them to take a peek earlier. If course didnt leave them open long.

 

I filled to almost full about 380 miles ago. Reading 8th above .25 now so yeah lol might end up in the shop sooner than Thursday when I get back into Arkansas

 

They suck from both and it goes to a t fitting then to the engine. Probably a plugged vent as stated above. Vent are by the suction/return lines.

 

Alright. I'll have to take a look at see. So they dont have "crossover" one tank to the other then to the engine.

Safe to assume if it sucks one dry I'll be dead in the water

 

No crossover anymore. Still available as a option but not many know about it. And yes. Paccars are horrible to prime with no special tools. You might have suction taps and could shut off the empty tank. We usually order with suction taps then install return taps as well. Gives you alot of options for fuel transfer/emergency's.

 

I see a valve on each side. The vent tube appeared to be clear. At least nothing in the end of it and no way to blow air either into the tank or into the tube to try and verify that it is clear.

I've got both caps off currently so maybe somehow itll at least even out the level some.

No stick to dip the tanks either to see if the level changes.

 

Amish hand turned is were it's at.

 

Happy anniversary y’all @blairandgretchen
