I removed the pump cover and it's super fricken dusty in there. Not sure how common for debris to get in there but it's covered in dust. I've been driving to work down a rocky / dusty road the past few months. I'm grabbing a multimeter now to see what I can discover.

The top of the tank is not sealed off from the road.

I had similar issues when I first had my walbro 455 hardwired. The car would just randomly shut off as I was driving. After a few minutes it cooled down enough for me to be able to flip the switch on the circuit breaker and I could start and drive it again.

Follow the wire back and see where it is routed. When the shop first did it, they routed it along the firewall across to the passenger side into the grommet which runs right behind the turbo creating extra heat. It basically overheated my wires causing a spike in amperage and popping the circuit open. I did feel the wires after one instance and they were mushy and hot.

If this is the case, just go out and buy like 15 feet of wire and reroute it through the driver side firewall grommet then behind the radio to the passenger side and back to the fuel pump. After I did this, it never had this issue again.

Thanks, I'll give it another look over.
