88 Bayliner with an aluminum tank....<br /><br />If I remove the fuel line going from my tank to the fuel pump at the pump, and apply slight pressure to the line, should the tank vent this pressure? I'm asking because when I did this, even with the filler cap off the transom, it seemed to build pressure in the tank and cause fuel to come back out the line when the pressure was removed from it. <br /><br />Does not make sense to me, I would think that even if the vent was clogged or had a check valve, the tank should vent with the filler cap off. <br /><br />Any ideas??
