UNL1MTD Posted February 26, 2010 Share Posted February 26, 2010 I'm going to be doing the RMS on the MJ and I'm thinking that it would be prudent to change out the 180k oil pump while its all apart. I'm trying to figure out if the High Volume oil pump is 'safe' to put in. I guess what I'm wondering is if the stock oil pump has kept up for all these miles is there even a reason to 'upgrade.' Anyways these are the two I'm choosing between. The high volume really does seem like a deal coming with a new screen and tube and at only 50 cents more. I feel like this is a no-brainer, but for some reason I am hesitant. Any chance the high volume pump will cause any other problems on the Renix motor? Stock http://shop.advanceautoparts.com/webapp ... 6998008___ High Volume http://shop.advanceautoparts.com/webapp ... 7002325___ All that said, I swapped in a full gauge cluster awhile ago and I've never had a reading from the oil pressure gauge. I did swap the sender out for the appropriate one, so I really feel like its the gauge and not the pump. The gauge just reads 2-5 psi during the entire time the vehicle is operating and the jeep does just fine, thats why I feel its just the gauge or possibly the brand new sender.
