Fuel Pump to Cover Seal

Do you guys use a gasket or sealer between the pump and front cover? If so, what do you use? Enderle cover, Hilborn pump, SB Chevy.

 

i just had this problem myself.

I have a twin engine tractor with enderle injection. The back engine seals just fine, but the front engine's pump had six holes drilled in it. The three holes that weren't being used leaked oil badly. I sealed it with black rtv, and it was fine. The rear engine that only had three holes didn't need anything, and no leaks.

hope this helps
