I just bought a boat that hasn't been run for years. They drained the gas out of the two 12gal tanks. It was outside in the oklahoma heat and I think it built up pressure in the tanks. Im wondering if theirs a way to relieve the pressure from the tank/primer bulb. Ive tried opening the tanks, sticking something in the Barb fuel line connector. I cant think of anything else to do, but cut the fuel line befor the bulb and see if that relieves pressure. Any thoughts would be great. thx
