Also i was running the pump on pwm. Tanks said i killed the pump ( gss 340) because of that but i tested the old pump after i got it changed and i think its a good spare. I think ecu was the prob not pump.
I have also read this. I am using a Walboro from tanks, inc, with their tank and you have to set the PWM to 100% or the pump will die. Again, I believe, FI TECH instructions don't speak to this.
