I just installed a holley black pump on my 98.5 dodge, has edge juice w/att. wether the power level is on 1 or 3. I have a fluctuation of 10-13 psi at idle. but at wot I get 5-7 psi. just seam way to low.

I had this set up on another truck with same set up with no problems.

not sure if I should stretch the spring or not.

need to figure this out, so I can giver a good beating.lol

 

forgot to add, that at stat up the alarm sounds at about 4-5 psi for a few seconds then builds up.

 

not bashing but IMO the Holley's and like OEM pumps I will never use. double check your psi with another guage to confirm. and if its that low. your pump is too low. I know alot of people have had there own success with a holley. but when you throw electronics at it that is wire tapped they mostly will not keep up...

 

take the 4 bolts off of the bottom of the holley pump and check the brass screen in it as this can clog. Install a pre-filter and you can remove this screen. You shouldn't need to stretch the screen in the black or blue holley as min fuel psi for these pumps is 10. Mine has worked well for 3+ years.
