4.0 oil pump oil pan modification

My jeep is losing oil pressure and as far as i can tell the bearings may be wearing out. I dont want a full rebuild but i learned that if i get a high output oil pump it may make the engine last longer. I also learned that i probably need to modify the oil pan to take the new pump and pickup tube.
Anyone out there ever do this and exactly what about the pan needs to be modified/how do you modify it? Thanks.

Re: 4.0 oil pump oil pan modification

Well if they are worn out I would replace them. Or you could Stroke it to a 4.7L

Get a new Oil Pump and see how it goes from there. That's all I can say since you want a new one.
