Changing the oil pump, because I can?

I have no idea of the mileage on my 304. I have to take off the oil pan to get my broken dipstick tube out. Should I put a new oil pump in while I'm in there?

If you're going in there you might as well do it now, or do it again later.

The oil pump on a 304 is external. It's at the bottom end of the timing cover. There are gear-to-housing specs. If yours are within spec, they don't need to be changed.

If you do decide to take measurements, and check it out, you'll have to prime the pump...fill it with Vaseline, before starting the motor.

I don't think I'll be changing anything at this point. Considering I didn't even know where the darn thing is. LOL I'll hit the rewind button and start my thinking process over. This is why I love this forum. If it wasn't for you guys I would be in a world of trouble.

Me, too. Between the forum, and my Factory Service Manual, I get by. Here's the perfect manual for you...

1977 Jeep Technical Service Manual CJ-5 CJ-7 :eBay Motors (item 270494697932 end time Dec-09-09 08:46:38 PST)

Believe it or not, this is a great price. These manuals usually sell for much more. I have that one, and a 1979 manual. Priceless!!
