Thanks for that feedback.
I notice NAPA has a 5.5psi pump
https://www.napaonline.com/en/p/CFPB...rdInput=b0189p. It has 25gph flowrate. The 9psi pump currently on the truck is rated at 40gph. Will the 25gph pump be an issue on stock engine? I have not and do not intend to hotrod the truck.
Is it best to stick with the higher flowrate pump (which looks more like the service manual (see screenshot) and add the extra complication of regulator and gauge, or keep it simple with a more suitable pressure output pump?
The NAPA 5.5psi,25gph pump looks more like the one for the 6 cylinder (other screenshot). The two pumps look like they are oriented 180deg different. Does the orientation of the pump matter?
Thanks.
