I have posted here before about this same fount that has had an unknown leak for awhile. I finally got around to giving it a dunk test today and found out FOR SURE its coming from the Check valve. I have already replaced check valve once assuming this was the issue. Notice in my photo how the air stem is cock-eyed, it has always been that way before and after CV replacement, and makes it hard to open the CV to pump air.

Has anyone experienced this before? And does it seem like there is any possible way for repair? Seems like it must have gotten dropped right on the pump, I'm sure the threads/insert for the CV got goobered up whenever it happened. The nickel is beautiful on it, it had been barely used when i bought it. If it were a beat up steel fount off of a E I would chucked it already...but never this one.

If nothing else, it is good decoration...i guess [frown] Click image for larger version - Name: 20160827_083457-01.jpeg, Views: 110, Size: 180.66 KB

take out the air stem and inspect it , it may have a slight bend in the lower end . were the CV threads leaking or was the leak coming from the center hole ? either one can usually be fixed . if its the threads try adding a small oring like the late CV's have , if its coming from the center just try another CV , dont give up !!!

The air stem is completely straight, it's as though the Check valve itself is not sitting in the threads straight, which is causing a leak through the threads. What size o-ring would that be?

It looks like the CV is cross-threaded. I think its unlikely the bottom of the pump tube is distorted. You may be able to remove the CV and use the air stem to guide it into place. I would check the threads of the CV and the ones in the bottom of the tube for evidence of cross-treading.

Brass is soft enough to form new threads fairly easily. You may need to clean up both sets of threads with a tap and die. Coat the tap with grease to capture any chips that may form.

An o-ring is not going to fix this issue. If you go slow and are carefull you should be able to fix this.

I had a 500 stove like that, it was as though the check valve was crooked. I removed and replaced it with the same results. Now mine did work properly, and wasn't cross threaded, and had no leaks with the stem screwed down, but it did bother me.

One thing it could be is that the check valve housing was a little crooked when they soldered it to the bottom of the pump tube. A little crooked down below would explain a crooked stem up above.

One of the things I like to use on all of my threaded connections is Indian Head gasket shellac and thread sealer. Use a long handled artist brush to coat the threads of the pump tube, do the same for the check valve. Let it dry throughly then assemble. It is fuel proof as well.

Thank you for your input everybody, the problem is FIXED!
I actually placed a 242 sized fuel cap gasket over the end of the Check valve, and it now holds pressure [smile]
