unfortuantly you're correct, they do offer little resistance to dripping some fuel, i've only had a few cases where fuel will just pour out of the tank but tha'st the reason i'm working with these new style valves. I just put one in a previous customers tank that was having overflow issues. I'd really like to test the performance on them before having more made but i feel pretty confident with them. Just so your aware the valves i'm using relieve pressure at 1psi so don't be surprised when you have a little pressure at the cap, but it should be a safe operating pressure to run if not then i will remedy it and get a lower PSI rated valve.
