It still keeps coming back to that - you shouldn't have to pump the
blub at all once you've started the engine.

It doesn't seem likely that it's somewhere on the engine. It still
could be the tanks or maybe even the fitting where the hose attaches
to the tank. You might want to remove it, tape it with teflon and
reinstall it.

I know this is also going to sound stupid, but when you pump the bulb,
do you do it horizontally? As odd as it may sound, on my Johnson 25
which has a new hose/bulb assembly and I have to tilt the bulb up and
pressurize it - the pressure won't hold if I hold it horizontal.

You might also want to check the filler cap gasket and the tank vent -
the tank vent may be clogged.

Other than that, I can't add much to what has already been done and
said.
