Re: Merc KE-4 gas tank question

I would love to have a tap of this size also. The small Mercury tank threads are the same thread as was used by OMC on their TD-TN motors. If fact, you can use the OMC cap if you want to. Carl would turn over in his grave, but the OMC cap was a real cap, not the cheap piece of junk plastic cap that Mercury used. The larger thread caps for Mercury came out when they went to a large fuel filter assembly that threaded into the bottom of the tank. That is why Dave Bernard wanted to see a photo of the bottom of the tank. I don’t have the sizes off the top of my head, but I think the small tank is 1 1/16" x 18, and the larger one is 1 3/16" x 16. These taps can be purchased for the $50 range, but that is a lot of money just to save a tank.
