IDMJ Posted November 11, 2018 Share Posted November 11, 2018 Doing the ‘89 to ‘99 swap and in looking at my fuel tank/ pump options I keep coming back to using my renix tank with an adapter ring for the ‘99 pump. Problem is, I can’t seem to find one. Anybody have a good lead or even have one to get rid of? Link to comment Share on other sites More sharing options...
ScottJeep Posted November 12, 2018 Share Posted November 12, 2018 In my experience, those pumps connect/lock WAY different. RENIX is a tabbed ring the 97+ XJ uses a very large threaded ring. Maybe I am mistaken but don't recall an adapter ever being mentioned before. Link to comment Share on other sites More sharing options...
HOrnbrod Posted November 12, 2018 Share Posted November 12, 2018 ^^ This. Amazon sells both the late model XJ fuel pump threaded nut and seal. You would have to cut a hole in an unmolested tank to use the late model pump. https://www.amazon.com/Mopar-5201-8808-Fuel-Pump/dp/B0049ESZUU/ref=sr_1_1?s=automotive&ie=UTF8&qid=1542042374&sr=1-1&keywords=5201+8808 Link to comment Share on other sites More sharing options...

IDMJ Posted November 12, 2018 Author Share Posted November 12, 2018 There were companies (copperhead fab, GenRight) who made adapters for installing XJ ho pumps in an MJ tank a few years back. I know the tank has to be modified. I just can’t find those adapters any more. Link to comment Share on other sites More sharing options...

IDMJ Posted November 13, 2018 Author Share Posted November 13, 2018 Thanks. I read that thread last week! I actually think after some measuring and thinking about it that I am going a different route. I'll document it..... Link to comment Share on other sites More sharing options...

I have one and, I’m not sold on that either. I’m thinking a TJ tank rear mounted. Link to comment Share on other sites More sharing options...
