Today I went to a cruise in, about a 30 mile drive. Got there everything fine. Left about 4 hours later, thought I'd take the surface streets back, air temp about 70. Gas tank little less than full. Got into some bumper to bumper traffic. A guy pulls along side of me and tells me there is gas coming out of my gas cap. I stop remove the cap clean the area and put it back on. About 6 miles later in B to B traffic I look back, the gas is coming out of the gas cap again. I stop do the same thing. Get on the freeway drive about 10 miles pull into my house, no leak. I have a Backdraft. Any ideas out there
