Here is the story: My brother-in-law has a 1990 FJ62 that he acquired last winter. It had been sitting for about a year. We could tell the gas was bad so instead of draining the tank (like I recommended) he ran the tank really low. When he filled it back up, the fuel pump went out. So after replacing the fuel filter and the fuel pump, he is still having problems. Here is what's going on: The problem only happens when he is on a major highway or Interstate. He commutes 30 miles daily and the vapor lock does not happen. It only does it when he drives it on a weekend trip. He is driving along running great until he slows down, like exiting off the highway and coming to a stop sign. When the idle comes down, it sputters and then dies. It will not start for about a half hour. He has to sit there for 30 minutes and then it starts. And,,,,it only does this when the ambient temperature is fairly hot. Above 85 degrees. Is this vapor lock? Anybody else have similiar experiences? What can he do? Any thoughts and comments are greatly appreciated.
