Outboard male fuel fitting plunger? Valve?

[guy48065]

Most of the photos of the male part of the fuel fitting show a thin plunger "nib" sticking out--but not all. Not sure if my 2000 Johnson 2-stroke 40 is supposed to have this or not. I can't get the bulb to build pressure, brand new fuel line. Replaced it because the old one leaked at the tank & was sucking air so had to buy an over-priced replacement due to the holiday. I think I'm hearing air being pumped into the tank, despite the new line/bulb.

​​​​​​​Not sure how to find out if the problem is the portable tank, new fuel line, or outboard.

Is the arrow on the bulb toward the motor? Your symptoms sound like all the other reversed bulb questions and symptoms.

Facing The motor.

Okay never mind. I went back into town & bought just the hose ends to put in my old line & bulb. Works fine.

I guess I just "lucked out" & paid $50 for a line with a defective bulb.

Due to some "clever" engineering, some fuel bulbs must be held upright for the internal check valve to work properly. If they aren't held in the proper attitude, they pump very poorly or don't pump at all.

This seems to be the case at times, no matter if the bulb is OEM or aftermarket. Don't know why.

I have noticed that in the past--especially with the stuff & "crunchy feeling" new bulbs, so I tried all orientations with no change.

Just bad luck. Unless this is common, of course.
