How tight should a fuel cap fit? I just finished up my tanks (9A). I totally expected the fuel caps to leak air while doing my leak test, but what surprised me more was the fact that water made its way into the tank when hosing off the soapy water. I wasn't pressure washing or anything, just had the "shower" setting on my hose and rinsing the soap residue. Is this normal for water to get in that easily, or do I need to address the fit of these somehow?
Attached is a pic of the style of cap that came with my kit.
