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.</blockquote>
