Howdy y'all. I bought an 86 GL Wagon (carb) from a guy who hadn't run it for 3.5 years. I have replaced the fuel filter three times. I'm still getting poor fuel supply, and before replacing the pump, I thought I would clean the lines and maybe pull and clean the tank. On the first filter change, there was a pile of rust sediment in there. The fuel seems clean now.

 

Does anyone know if there is a "pickup" with a filter sock on it inside the tank? If so, that is probably the culprit. Can that be pulled out of the tank without removing the tank?

 

By the way, if it is unlikely that the line in the tank could be plugged, can the fuel pump be tested somehow? I also thought about reversing the fuel lines on the pump to blow out the blockage.

 

Any ideas are greatly appreciated.

Have the fuel pressure tested. That will tell you a lot about how the pump is doing.
