C15 primer plunger

Hey guys, I'm about to replace the hand priming pump on my Cat C-16. Does anybody know if the gasket on the bottom of the pump needs to have anything applied to it before installing, or do I just put it on with the gasket dry?
Thanks,

Put it on and go. Yes.... dry.....

 

Mine did the same thing while on the road but was leaking pretty bad. Nighttime and no parts store open. I had an old sleeper air bag that hadn’t found its way to a dumpster. Cut a new gasket but left the center hole covered up. Worked like a charm.
No need to pump up after replacing.

 

I put a priming pump on mine thinking it would make filter changes easier... nope. Worthless piece of ####.

I ended up putting the block-off plate back on. Loosen the return line, a minute or two of cranking, with a rest in between, fills the filter up and away she goes.

 

I just buey one. Its $ 153.46 total

 

I jus buy one. It's 153.46
