I have an FJ 43L -KO, serial number FJ 43–68092. I have a 2F engine number 451572. Most of the parts that I have been putting on this all know have been for a 1977FJ 40, the parts for the FJ 40 1980 which is what I was told this was don’t fit or don’t match pre-existing parts. This vehicle runs great the only problem isThat once I start driving down the road and the engine heats up it stalls out on me. And when restarted continues to store until it cools down. I believe the only thing I have not replaced on this is the fuel pump and I think that may be my problem. I just wanna be sure that I put the correct fuel pump on. Any help out there from anyone familiar with these foreign rebuilt FJs?
