No longer losing its prime. Still having issues with alot of white smoke at start up n smoke thins out after warm up but still has white smoke. So far I have changed the soft line to the pump, fuel pump, fuel filter, filter head and injectors.
As far as I know they are all working. Can still get the truck to start in cold weather. Just thinking the air problem due to the white smoke n I get air coming from the Schrader valve while the truck is running.
Did not change the soft line from the hard line to the pump. Probably be trying that next. Have a part number on the check valve? If none of this works i will be doing the selector valve next.
Have a 88 f250 with non turbo 7.3. Truck is losing its prime. So far I have changed the fuel pump and fuel filter and fuel filter head. Both tanks are full. Gauge in the front tank does not work n gauge in the rear tank does work. Could it be the fuel tank selector valve causing it to lose it'...
