Melling Oil Pump Pick-up- which one?

[Jim V.]

When using a Melling M-55HV pump on a 65 S/B which Melling pick-up is used?
55-S1, 55-S2, or 55-S3..
I understand the M-55HV (high-volume) is about a 1/4 inch taller than the M-55 and therefore uses a longer pick-up. Also, anybody care to share any tips on measuring pick-up depth when test installing the pan?

Thanks again...

Oops.. I mean the 55HV uses a shorter pick-up (since the pump body is taller)..

Jim - I can't tell you which pick up is correct, but I can tell you how to measure the depth. I use a wad of that green clay my wife has you can stick fake flowers in to arrange....I think you can buy it at WalMart, Target, Kmart, etc. It works great, and leaves an impression, which you can later cut through with a knife and measure the depth. This also works well for checking valve to piston clearance when assembling an engine....Craig

Also - make sure you tack weld the pickup after installed, and use one of the Melling driver tools to drive the pickup into the pump...Craig
