Drove the Jeep to the beach and back this weekend, about a 6.5 hr drive round trip. I replaced the u-joint in my rear DS and adjusted my pinion angle a few degrees and it's running great. In fact, I think it might track straighter down the highway now than it did the day I bought it and the ride is perfect.
However, I have a minor issue I need to figure out now. Filled the cell before I left to the tippy top and no leaks from around the ring. That's good news
Now after I had driven about 100 miles I got down to about half a tank and started having an issue. I'd be driving along fine at a steady 60mph, about 2600 rpm and suddenly the jeep would loose all power for about 5 seconds like the engine was cutting out. After 5 seconds of feathering the accelerator power would come back and I'd continue on for another 10-15 miles with no problems. But then it would hiccup again. It continued doing this regularly all the way there and I stopped to check, nothing visually wrong, no leaks, nothing. It just felt like the engine wasn't getting fuel for 5 seconds at a time every 10 -15 miles
So, at the beach all weekend while making short trips here and there and no highway it never had the issue again. When I left earlier this afternoon to come home I went again about 15 miles without issue and then it hiccuped, did it again about 5-10 miles later. So, I stopped and topped off the cell. Got on my way again and everything was fine. I kept the cell above 1/2 a tank the whole way home by stopping and topping off and it never once acted up.
So I'm suspecting a fuel related issue obviously. What I can't figure out is why. Is the fuel in the cell getting agitated enough that the pump is sucking and air bubble every once in a while? My cell is hard mounted to my tub which is a little more hard mounted to the frame than most with my cage tie-ins. That and my poly motor mounts make for a little more vibration than usual. That's the only thing I can think of.
Anyone have any ideas?
No CEL and gauges reading normal. Just the brief loss of power and it's other wise running better than ever.
