nut for oil suction is important,as over lightning will crush the tube,i made a tool to drive into the tube while heating it to reshape(pan off) then do not over tighten i snug the nut if it drips over night just a small amount of tighter till no drips. i do not use the ring with the metal crush sleve. runs 25 psi at idea 55 to 60 hot.run 5/30 oil,with gear typ pump.

Meteor is quite possibly on to something there. A replacement pump I had here came with a tag which stressed making sure that pump seal is installed straight & carefully snugged into place.

I liberally coat the rubber grommet with white grease before installing it on the tube and into the pump housing.

Ted,
Instead of axle/bearing grease?  White grease couldn't contaminate the oil then?

Oops. Sorry. Confused about which surface exposed. Still, question is relevant for pan/valve cover gaskets, etc.
Is white grease contraindicated for surfaces exposed to circulating engine oil?

I’ve no problem with using axle bearing grease as an oil pump rubber seal lubricant as long as it’s clean and not used in excess.  Depending upon the brand, it may have a higher melting point and could ultimately end up in the oil filter or in the bottom of the pan if used in an excess.  But simply using it to coat a rubber seal should not be considered an excessive amount.
 
The white grease I use is clean (Lubriplate brand) and has a lower melting point than the typical wheel bearing grease.  If a little bit of it ends up in the oil, then it’s fully melted at 140°F and essentially of no consequence.  While I use white grease as a sealer on some of the various gaskets and seals, I do not use it on engine bearings or as a cam lube.  It can stop up the oil filter if used in excess and if used as an engine assembly lubricant for the bearings, then the potential is there to hydraulic the bearing surface if it cannot squeeze out adequately when the various bearing caps are being torqued in place.
