I had to change the plastic center section of my Racor system to get it to stop leaking. My electronics also did not work. I installed a copper flared fuel line on the outlet side of the system with a tee, then a valve, and a second tee. I then installed a bypass around the valve with a cheap fuel pump from NAPA. When i go to prime after a fuel filter change I simply close the ball valve, fire up the pump, and depress the quick connect on the supply side of the unit injectors near the back right of the coach at the cylinder head. Once you get fuel, shut off the pump and open the valve.
I have had no leaks since replacing the sight tube and o-rings.
