Ok here's the deal.
In the final stages of a rebuild and I have a Melling M55HV pump that was in my old motor when it blew up. That pump is high pressure, high volume. I never had an issue with pressure, but needed a new one after the blow up.
I bought a M155HV pump which is standard pressure high volume. I did not realize that the pick up tube on the new pump is a 3/4", and my old pick up does not fit.
I can not use the old pump because the gears are all pitted.
Can I use the pump cover from the old H/P-H/V pump on the new S/P-H/V pump? The covers appear to be identical, and the old one is in nice shape.
The off season budget is planned out to the nickel right now and a new 3/4" pick up costs more than the pump did. The money just isn't there. If I have no options I will will order a new pump, but I am avoiding that if I can. I believe the only difference is the spring, stiffer spring in the older High Pressure pump. Couldn't I just swap springs?
