could verry well be .... it happens all the time ... take a piece of card board ( plane ol box cardboard) put a drop of your oil from crank case on it ... you will see the oil seep into the card board but .... if you see a halo around it grow quicker ... that's fuel and its your pump ...

I honestly have no idea, I took everything that was in the filter head off, cause it had bits of rtv dangling off, cleaned it and resealed it with thread sealant. Didn't see any check ball while I was around it

If its loosing prime , its gonna be near or it is the fuel/water seperator ...... does urs have a bowl on the bottom ? If it does , go to local parts store and tell them ur looking for a Baldwin filter number BF1222 equivalent ..... buy the wix if possible ...... if it still happenes the line from the filter housing to the IP has rubber bushings in it ..... they go bad .... if u can pull the line off and the two fittings one @ filter and the other at IP .... go get a few fittings and makeit a cloth braided hose .... that should be the total solution ..... if not post results .... and video if possible
