Interesting , just did a build with a 63HP and didn't experience any of this .




You sure you have an HP and not and HV they sell 3 stock, High volume HV and High Pressure HV.

When I went to the speed shop with the HP he said I will not sell them just HV or stock. He said his book said industrial motor only with canister type filter.

And yes I checked the bypass even put a stock spring in which did not help much at all.

Put one of my used mopar high volumes on and it was fine so then got a new HV and it was fine the gears are totally different!


Well I see the melling hp is just a stock pump with stronger bypass spring??
This one years ago had tall gears like a high volume but real sharp?? may have been a Federal Mogal bin a while but it was dangerous. took out 3 140 hp oil gauges as well as filters.
