I just replaced the fuel pump in my Jeep because the Jeep would lose pressure. Jeep ran fine for awhile now it’s bogging down again. It only does it when I get down around half a tank and it doesn’t do it all the time. Anyone know what could be wrong?

 

I would go at the fuel psi. Hook up a fuel psi gauge, leave it on where you can see it, and drive... See what it does under load in different conditions, if the pressure is within specs?

 

You could be posting in the Grand Cherokee section instead of in the Cherokee section.
