Re: Pressure Tank Problem

[jerry-ahrens]

I’m surprised that pumping the primer button will help it run, despite the fact you are getting good pressure build up at the tank. When you open the tank, it should have a lot of pressure inside, not just a small amount of ”hiss” when the cap is cracked open.I think it would be wise to do a complete go thru on the tank, and check the valve that Chris mentioned. There are also two metal ”discs” located under the diaphragm. They are easy to loose when taking the assembly apart. Another common leakage [air] point is the pressure relief valve disk. The pressure relief valve releases excess pressure build up out thru a small passage [hole ] on the side of the tank cover [housing]. I like to use my wife’s Widex bottle to check the entire assembly for leaks. On an EMPTY tank, I use an air blow gun inserted into the ”air” hose and while leaving the ”fuel” hose still hooked to the fuel connector, go ahead and give the tank a couple shots of air. Don’t try to inflate it, just 2 or 3 psi will do. Use the Windex to find any leaks. Now, if you put to much pressure in, the over pressure relief valve will open to relieve the excess pressure inside. This is normal. You can make your own cork gasket easily, or drop by the dealer for a new one to make it easy. Myself, I prefer the cork and tank surfaces to be clean and dry with no sealer.
