Prime oil filter before installing?

If you look at the diagram on the side of the Fleetguard filter it shows prefilling. I have never prefilled any filter on any engine. As said above, if you fill through the center you are pouring oil on the clean side of the filter. A little piece of the bottle seal foil that comes loose will surely make it's way to plug an oil jet on any engine I own.

I believe it’s recommended to pre fill. Just changed mine and pre filled the EaO80 and accessed from the TOP .

I agree and do so when I can. Some filters you can't, such as vertical or inverted. My Fiatallis grader w/5.9l Iveco had two filters inverted, no choice. Then my old Mack with 300 Maxidine had two large ones, upright, I always filled them.

I believe you can purchase prelubers for engines. They pump oil through the engine prior to start up.

I haven’t seen one of those for a long time.

Oil and block machining have come a long ways in 40 years, I don’t think they are that popular or warranted anymore, for most applications.

I've a preluber on my on old truck and a pal on a KT19, both which tend to sit month(s) at a time. Cummins makes a prelube/quickevac for Q38 and Q50 marine engines they state will empty the sump in 60 seconds...and they hold 40 or 50 gallons?
