Fass blowing relays

Posted

I have a fass 165 gph that I've had on my truck since 2014. Lately every other time I start my truck I have no fuel pressure and it stumbles.

I replace the relay in the wiring harness but it does it again. What's weird is that the fuse isn't blowing but the relay is.

Relays aren't cheap I need to figure this one out. Any ideas?
