I desperately need some sort of aftermarket fuse junction block. It should be weather sealed.
I've been tracking gremlins in my fuel system. The pump has intermittent performance. I tracked it down to overheating relays and fuse block under the hood. My fuel pump is aftermarket which runs at 11 AMPS... Around 140 watts KOEO. I bought a few parts to try and make a bridge gap till I could find a better solution. I jumpered the junction block PCM signal to an external relay and wired it up to bat positive with a fuse and spliced into the wire to the pump. I digress though... It worked until the PCM overloaded. I was driving and the PCM just turned off. I had to remove my jumper, put in the original relay in the junction block... then cycle the key a few times. The PCM finally booted and I was able to start the truck. However, using the fuse block aggravates my problem with junction block overheating and the pump stops working.
Long story short, I desperately need a solution that's weather sealed (for under hood), has a relay and fuse that I can wire up to bypass the junction block reliably. Been searching the internet and see lots of chinesium junction blocks on Amazon marketed for boats. Maybe a weather sealed relay with harness I can splice a fuse into? Any ideas?
