[QUOTE="FordTechOne, post: 1496697, member: 35543"] The issue is that the Battery Junction Box (BJB), which was made by Japanese supplier Yazaki, was not manufactured to the fuel pump draw specifications provided by Ford Engineering. Yazaki was convinced that the issue was the fuel pump drawing excess current, so they flew an engineer out to inspect a vehicle that was exhibiting the issue. They found that the fuel pump amperage draw was well within spec, indicating the this issue was the robustness of their fuse terminals/circuitry causing excessive heat buildup. As others have mentioned, long drives will cause the most heat buildup which can cause the issue to occur. If you only drive locally for relatively short distances, you’ll probably never have an issue. [/QUOTE]
