Mine's harder. With the 01 intake and the 04 TJ steering pump, there's very little wiggle room for the fuel lines. I had to bend the fuel rail nipples slightly to fit them in. Thus I disco the fuel lines when changing injectors.
Last time I disconnected the fuel lines from the rail in my RENIX Jeep, it cost $25 to put them back together. The FSM says to replace those little plastic fittings if you disconnect them, it is a "disposable" seal. Guess what, those little plastic thingies are out of production, last I heard....
My last engine swap, the fuel rail was hanging off to the side, still connected to the fuel lines. No leaks there, yet.
