Don't know if this is a common problem with the little 4 banger jeeps, but it's kinda suddenly developed 0 oil presure at idle. keep it at about 13-1500 and ther's lots. I'm thinking the oil pump is shot. Anyone have this problem? Anyone know of a high output oil pump?

They are not known for that kind of issue, have you actually checked the oil pressure with a mechanical guage? I have seen lots of the sending units fail in those things.

Also if the oil pressure is truly low check the crank and rod bearings, the oil pumps in those things are very similar to the SBC design and are not known for failing, not saying they can't fail, it is just very uncommon.
