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?

How long do these pumps usually last, because they're not cheap

My airdog failed, tried to get parts from airdog no luck, got a fass. Salesman said it'll last a million miles, I highly dough it. My next one will be mechanical
