I just had my oil pump replaced with the
Melling M295HV-324S kit that includes the oil pump and the oil pick up tube and o-ring assembly.
I definitely recommend getting the kit with the tube and o-ring to make sure you have a matched set with the correct o-ring.
That is very important and worth any cost difference between the kit and a oil pump without the tube.
I could not be happier.
For the first time in years, I finally have full oil pressure across all RPM ranges.
Clearly, the best money I have ever spent on this engine other than the rear main seal repair.
While my engine was not making any noises before the repair, it now runs smoother at idle and all RPM ranges, is quieter and I swear it has better power across all RPM's.
And I was just looking to improve my oil pressure beyond what I had gotten with changing the oil pickup tube and oil-ring assembly a while back.
I am now getting a solid 40-42 PSI at hot oil idle and 55-60 at off-idle cruise.
WOT will send the needle to the top of the scale during hot oil situations.
Cold oil idle pressure is 50+ PSI.
These are the numbers I remember getting many years ago.
Not too bad for an engine with 230K+ miles on it.
I wish I had followed my gut and replaced the oil pump many years ago.
