Hello all! I have a question that I hope has an easy answer. I have a 1995 Dolphin RV with a f-53 super duty engine. The question is, how easy is it to change the oil pump? Does the engine have to be lifted ? Any recommendations would be appreciated. Thanks in advance.

I guess the easiest way to answer you is to say crawl under and look. If you can remove the oil pan easily you can change the pump

No mater how high you lift the engine, the cross member is in the way of removing the oil pan.
You will need to slide the cross member forward, which involves removing some bolts and stuff ahead of the cross member. The cross member will not come out from between the frame rails.
I built a wooden stand to support the engine via the harmonic balancer.
Please DON'T install a high volume or high pressure oil pump. A Mellins standard pump is all you need.
The roll pin that holds the distributor gear on the distributor shaft will sheer with the HV or HP pumps.
If you don't believe me, go ask the roll pin question on this Ford forum.
Been there, done that.

Changing a oil pump is not an easy task. If the oil pump failed, there is likely other damage to the engine that will create difficulties later on. If you're wanting to replace the pump due to low oil pressure, that may not really be the problem.
At best, you must lift the engine high enough to remove the oil Pan just to get to the oil pump.
Understanding why the oil pump should be replaced is really important. They generally only fail because of other problems with the engine.
