Well ended up replacing the HP FP cuz truck wouldn't start after oil cooler install last week.On the old pump seem like I would hit 24500 on wot running hd300 with this pump it only hits 23600 then goes down to 21000-22000 psi
What could cause this with new pump also replaced both filters,could the lp pump cause this?
Is it time for a fuel lab velocity??
