You don't have to replace the pump. Simply add an inline check valve near the existing fuel pump and you're golden.

I'm 99.9% positive that all of the fittings out there are a standard size. Any fuel pressure gauge will fit.

i just lost mine and it is 80 bucks to replace and its a PITA to get to due to the fact its on the back of the engine. but its not terrible pricey for a jeep fix.
