I had a feed problem from my rear tank on my C20 since I bought it from the PO. It would run fine for a while and then act as if it were running out of fuel. He even installed an electric fuel pump wired to a toggle switch to try to solve the problem. It still did it. Mostly happened on the highway. Took the tank out and found a sock like the one pictured....in very bad condition. Tossed it, cleaned out the tank and put it back together. It feeds perfectly now...no need to even turn on the electric pump anymore. I didn't think that the sock could have restricted it but it appears as though that was the problem on my truck.
