Could also be that the rubber hose inside the fuel tank that connects to the pump is split.

If you do decide to replace the pump, do not use Airtex brand.

Alright, I'll probably just replace the fuel filter since maintenance on this thing was crappy before I got it. I'll also drop the fuel tank this week and take a look inside.

Checked the tps last week it's running fine. But after I get the pump and filter taken care of I'll do another check.

Yep. One thing at a time. Address KNOWN issues first.

And, just because something fixed a symptom on someone else's Jeep doesn't mean it's gonna fix yours. Most symptoms can be caused by multiple things. Stick to your way of doing things.
