HI Everyone,
I have a Holley 750 fed by a Holley Blue Pump and the regulator that looks like the one that comes with most of the Blue pump / regulator kits (Came on the truck when I got it) there is no return line on this set up.
Other than being really loud, I have not had any issues with this set up, lately the pump sounds weird to me (like it’s struggling and not as high pitched as in the past) and I’ve been afraid to take the truck too far in fear that the pump will die. It also makes a purge sound on occasion which is new to me.
What’s the best way to diagnosis this pump? I don’t want to buy a new one just to have the same issues. I did go through the wiring and it looks ok and I cleaned the connections.
Thanks for any input.
Chris
