Is the filter before the pump?
Don't see a return either.
How far is that pump from the fuel tank?
Should be real close, as those pumps are 'pushers', not 'suckers' like the OEM engine driven ones are.
Next time the v'lock issue happens. Take your gas cap off, and see if it runs better.

The filter is before the pump and the pump is bolted right outside the tank. Those visible bolts are the ones holding the tank in place. I found a spot today where the fuel line runs REALLY close to the exhaust (like less than an inch away). I'm thinking this could be a problem. Ideas?

Hope your not run'n that rubber hose all the way to the engine.
That hose will suck up heat PDQ.
What PSI is the pump built for? Is that rubber hose built for the higher PSI? Unless the hose sez it's for FI, it's for carb'd use(under 10psi)only.

Its only rubber where it connects to the fuel pump and fuel filter as far as I can tell. The line that runs to the engine is metal. And the fuel pump is supposed to be 15 psi. I had it put in by the shop that towed me a couple weeks ago.

Is the pump run'n when the engine dies?
When you cold start. Can you here the pump shut off before you start?
What's the ID of your fuel line? SB 3/8" min.

The pump does run when I try to restart it. I will go back out and look for an ID on the line later this afternoon and will post a picture of where the line runs near the exhaust.

Here are two pictures of where the fuel line runs extremely close to the exhaust. I feel like this could contribute to vapor lock but would like y'alls professional opinions.

Im not too sure, I will have to check again. And yeah I figured that was a bad place for the fuel line. Do you think it could be causing my problem?

At the least, it's a big fire hazard!
Do you store gas next to a heater?

So I have found someone smarter than myself that is going to give me tutorial on rerouting metal ruel lines this weekend. Hopefuly by next week I will have it moved and maybe the jeep will be running a little better. I also think I need a radiator flush becasue its running a bit hotter than normal.

Keep the f'lines AWAY from heat and from be'n rubbed.
Have a 'rod-out' done on your rad. It's the best thing........
Google is you friend for this info.
