After reading about the holley Blue pumps I started to get low fuel pressure. My meter read 5 psi. I replaced it with a carter 180-P4601HP (jegs part number). My problem is now my meter reads 4 psi.

Do I need to adjust the pressure for the carter pump? Does the carter pump deliver 14 psi right out of the box with no mods or adjustments? What is the typical pressure seen when installed on our trucks?

Thank you for the help....

 

i just put a new carter oem lp on my truck. i don't believe there are any adjustments to the carter. could be a faulty overflow valve? how are your filters?

 

I just had the filter changed, less than 1000 miles on it. I changed the filter hoping to get rid of the puel pressure issue.

My thought now is the fuel pressure gauge is faulty. I'm borrowing a 10 PSI test guage and see if it will peg the meter.

 

arroyojim,

How many miles were on your truck before you sarted to use B100? make B100 for my VW Golf TDI. I did not want to try it on my truck with 190,000 miles.

 

about 130k. what are you worried about? just change yuor f. filter a couple times during your first few tanks.

 

That is good information! Thank You. I was worried about gunk getting into the injection pump as B100 is a great cleaner!

 

there should be sufficient filtering pre-ip. maybe add a supplemental inline fuel filter b4 you switch over?

 

Adding filters will be good. I will probably add the twist on quart filter near the tank. Thanks for info. No to restart my B100 production....
