I will keep this simple. This 1984 FJ60 is box stock and mostly original.
I have driven this 1984 FJ60 a few hundred miles without any issues then one evening I filled it up with gasoline and went to go play. About 10 miles after leaving the gas station it stumbled and died. I blew out a very dirty fuel filter and reinstalled it. That got me about 5 miles which were enough to be back in town. I blew out the fuel filter two more times on the way back home.
Since then, I have replaced all rubber fuel lines. Fuel lines have been blown out. Fuel pump replaced. Fuel filter replaced. Carb drained and needle and seat cleaned with carb cleaner. Carb has not be gone through because when the carb has fuel getting to it, it runs very well. Fuel tank drained, filled and drained two more times.
In the morning, the FJ starts good and runs great. But it will only go about 8 miles and then the fuel filter runs dry. If I let it sit overnight, then it starts and runs perfectly for another 8 miles. This time that it occurred I blew backwards through the fuel filter (which was clean) until I could hear bubbles in the tank.
The FJ started up and I drove it 8 miles back home. Once I am at home and let it sit for 45 minutes, the fuel filter is clear full and there is an occasional bubble going backwards through the filter to the tank.
Three possibilities: 1) vapor lock is happening. 2) Fuel pickup screen is plugged from potential bad gas from the initial start of the problem. 3) Fuel lines reversed on the fuel pump or at the tank.
Thoughts from the forum, please.
