Did either of you notice any difference in performance after the mod? How loud is the pump? I have had people comment on the noise of the pump.
Has anyone tried the Holley red 12-801 pump? It has slightly higher gph rating not much, but it is diesel rated and I was curious if it was quieter.
Also the p4070 has 1/4" npt fitting the holley has 3/8" . Would the 3/8" make it more difficult to install, I have not looked at the line size under the truck yet.
I mainly want to install the tank kit and pump to eliminate a plugged screen or fuel delivery problem that I may be having. I am not sure thats my problem but I have eliminated about everything else.
