I have posted several questions about my electric fuel pump, about it loosing its "prime" so to speak after about 20 min of running time.
My question is how critical do you think battery voltage/amps would be to the overall effect of the operation to the pump and its ability to maintain proper pressure.
Reason why, is that during a last ditch effort of checking everything possible, we found out that the ALT. is not charging at all, so the truck has been running off the battery. We have been charging the battery after every run just to maintain its proper charge, so the Alt was a given that it was working.
Could the battery voltage/amp be falling below the required 12v after about 20mins of running time to cause the pump to slow down just enough to loose its "PRIME"???
Before I have to go out and purchase a new Pump.
Everyone I have spoke with states that they have never heard of a BLACK PUMP go bad before, and I tell them " Yea, they don't have my LUCK!!
