I have an 1988 skeeter starfire that I purchased not too long ago. The boat is in great condition and it runs great. The one problem I'm having is trying to pump gas into my gas tank. Gas pump handle wants to shut off right away because the gas is backing up too quick. Takes me FOREVER if I want to pump gas into my 42 gallon tank. I just have to barely squeeze the handle so the gas does back up to quick. Any ideas? Is it getting air locked?
