when I unscrew the pump to use air hisses out, then after pumping(which is difficult,  cause the pump gets stuck when pulled out) fuel shoots out the air hole after you remove finger to tighten back up.

Welcome. If the tank is overfilled and the check valve is stuck open, fuel will shoot out of the pump shaft. The other possibility is a rust hole or some sort of breach in the pump shaft.

Sounds like the check valve.  If you don't have a check valve tool -- empty the tank, pull the pump out and unscrew the brass rod.  Then hit it with a loads of carb cleaner.  That should hopefully eat any junk on the check valve.  Put the pump on (no fuel in tank) and pump it up to check.  You may need to repeat the process a couple of times.

Thanks for the quick responses guys, I'll give that advice a try 👍forgot to mention though it was new in the box from 1984, could that have anything to do with it?

Fuel coming out of the pump tube will only happen if you have too much fuel in the tank and tip the tank too much.   At the base of the pump tube, there's a snorkel attached which puts the air into the top of the fount/tank.   With too much fuel and tipping, fuel can get into that snorkel and flow down to the base of the pump in the check valve area.  If so, that's what's squirting out and should only last maybe a second before it's purged.   Note that the check valve is designed to stop air, not liquids, and as you see, they easily pass fuel.   Regardless, this is not something you want ever happening with naphtha (Coleman or Crown fuel).  With a kerosene stove or lantern, it'll make a mess, but not likely to ignite since it hasn't been heated to the point of vaporization.


Although theoretically possible, it's unlikely that the snorkel came unscrewed from the pump tube.   I've read of this happening once, but have my doubts.

Bottom line, I bet of you remove some of the fuel, your problem will immediately go away.

Flammable liquids, open flame, what could go wrong?


I've missed you!  But I'm reloading.

On a half tank, air still hisses out of it.  I'm gonna take it apart and tinker with it the next couple days when I have spare time

Get a bamboo skewer and poke at the center hole in the check valve,  The ball is probably just stuck from sitting for years.

+1  Also, keep in mind that it's not unusual for some air to leak a little before you actually tighten the pump knob.
