Tired of having a poor selection of oil filters for your Renix Jeep? Limited availabilty a pain for you? 20mm threads? We don’t need mumblemeter threads on our oil filters.
Here’s a simple mod that allows you to use the very popular SAE threaded oil filters which are more readily available. The old standard 3/4″ SAE thread.
You can purchase a new oil filter nipple from the dealer for under $10 and never be bothered again. Part number 53007563AB. It’s the one on the left. 
Or, grab one off a 91 and later XJ at the junkyard. Be forewarned though. You need a 7/8 wrench to remove a Renix nipple, but a 15/16 wrench for the later style.
And just in case you need to replace your oil filter adapter o-rings, here’s a handy guide.

Thanks cruiser 54, been getting tired of looking for different filters for my Cherokee and Comanche.
Cruiser 54: I Just put the part on from the Jeep dealer to change to the S A E filter. Because of space limitation, I had to use a deep well socket from Sears (it was the only on deep enough) to get the original part out, and a one inch regular socket to install the new part instead of the 15/16 one specified, otherwise everything went very well, thanks!
Sorry, have not already said that.
Thanks Cruiser
You’re very welcome!!
Cruiser, my Comanche has 275K on the clock. The oil pump ( new sender) puts out just under 20 psi at 750 rpm hot idle. I don’t know if the pump has been replaced before or not. At about 1500 rpm the pressure is aroun 30-36 psi. Could the pump be on its way out? I need to change the oil pan gasket any way, mabe I should change the pump any way. What do you think?
It couldn’t hurt, but you might verify the pressure with a real gauge first. Our dash gauges and senders seem to be hit and miss.
Ordered the Mopar brand adapter and filter. Haven’t seen any videos and or photos of the swap. Do you have to pull the whole adapter to swap the nipple or can it be swapped on the block? Thanks!
Only the nipple
Thanks cruiser! Appreciate you dedicating your time and expertise to help us all out!
You bet!!
Hey cruiser, back again for some advice lol. Im doing a lot at once as you can obviously tell. Read quite a few forums and obviously you were speaking on the subject there as well. I attempted to get the metric long shaft nipple off on the truck, but it was rounding the ends off. I just went ahead and replaced it with a Fram in the metric thread. Im swapping motor mounts now so I just went ahead and removed the adapter, but its the same and just getting worse. Feels like its several hundred plus Ft pounds on it. I went ahead and ordered a ZJ adapter, I’ll be able to still use this down the road on one of my 89 XJ’s. Is cutting down and easy out the only real viable option here? Can’t imagine how this thing was ever tightened like this. Once again thanks for your time!
A box end wrench should bust it loose.
did you spray it with penetrating oil first?
I did not, I think the taper at the end of the socket may have rounded off too much. Im going to try that today though. I just assumed it would be well lubricated from being in the oil sending circuit
LOL. Great assumption. Good luck.
