Jeep starts fine sometimes, runs, restarts.
Sometimes will start, but not stay running. Found little to no fuel in injector bar valve when this happens. When it runs, plenty of fuel present.

If I need to replace fuel pump or relay, where is the fuel pump physically located on the gas tank?

Do I need to drop the tank? I just filled it up before this problem started so it's going to be heavy with fuel.

Is there any tests I can do to find out if fuel pump is the cuprit?

Help!

If the pump is running but creating low pressure it is probably the pump. Yes it is located in the fuel tank . You will need to siphon the gas out.You will need to verify fuel pressure or lack of at theengien with a gauge (see video). If you do replace the pump, it is a good idea to change the filter and relay
