Standard off the shelf advance auto replacement pump. Anybody make a softer by-pass spring?

That doesn't sound right Sounds like they sold you a high volume or high pressure pump and said it was a standad pump you can cut one coil off of the spring, especially if it is the black spring. I'm assuming this is a BB and not a SB Mopar, either way the pressure is to high and you can trim either spring to reduce pressure if you can find a spring that will reduce the pressure. I trim almost all of the new springs on the high volume pumps I use, I like to have 10 lbs per 1000 RPM, or 70 lbs at 7000 RPM I do break the motor in with 5W20WT oil and wait until the oil is hot before starting the trimming process, rev it up and read the oil pressure and go from there




Good advice!!
