On a Merc, they have those snap connectors. If the silver snap is not

The silver snap only holds the connector on. The real connection is
the "O" ring in the connector around the probe with the holes in it.
The pointed one with the flycut around it is the retainer the snap
grabs
When disconnected there is a self closing plug in the connector.
If you are worried about an air leak, look at the fuel filter inside
the engine. If it is fairly new you can see through it and see if
there is air in there. If the filter isn't new, get a new one. That
may be your whole problem.
If there is air after you pumped it out, it may be time for a new fuel
hose, connector ball etc or the problem could be going the other way
(fuel pump, leaking internal hose etc)
That is why it is handy to have a spare, known good hose setup.
I have a spare without any tank end connection so I can stick it
through the filler neck directly into the gas, just for
troubleshooting.

Ah, another gas filter INSIDE the engine? I'll have to look. I did find a
kink in the hose where it goes through the aluminum bench. It has to be
routed a special way, and the tank turned backwards to what one would first
suspect. Did get a new filter, tho, and will take it for another run soon.
The old filter showed no resistance when I blew back through it. I think it
was the kinked line, but still could have problems on the next run if the
inside the engine fuel filter is clogged. Working this out one thing at a
time.
