Not OP's problem but I had a yellowjacket in my crossover line and kept acting like it was running out of gas.

No, I didn't, but that was a long time ago and I would have noticed. I just looked at the cap, and it looks fine. The little spring loaded vent pushes in and springs back out. I can't imagine what I never noticed it before, but maybe it's been hissing forever. I was just wondering about that little hose fixture that sticks out of the tank there. Never new what it was for. Maybe I'm just looking for a reason to complain.

Yea, it's probably working correctly. It was warm in the sun the last couple days, so I probably just noticed it because of the warm days. Today it's cloudy and cool (what happened to the sun???), but no hissing today.

I think it got in there when I had the tank off doing head work.

Yeah, it's been cloudy off and on today. Mostly high clouds. Hope it's as nice tomorrow as they're forecasting, 'cause a buddy and I are going riding. It shouldn't be as crowded in the Daytona area on a Tuesday as it will be this weekend, because it's suppose to be sunny and around 80 Saturday.

I've had issues with mine pissing fuel out the cap. I've also been having my caps coming unscrewed. I'm about to the point of buying a new set due to always having to monitor them. I've lost the left side before. It sucks.

I have a 1988 FLHTC and it builds up pressure also. I don't worry about it. I have pulled the tank and everything is as it should be. You'll notice that there is what appears to be a vent tube at the back of the tank under the seat area. Mine appears to be soldered and pained over at the factory. It doesn't affect performance in any way except one thing: trying to squeeze a few extra drops of gas into the tank on a hot day and then storing it in the garage will mean it runs over and stains my tank. Other than that I haven't seen any negative impact.
