happened at 3 pumps, and I use those pumps often seeing as that gas station is only 2 blocks away.
when I looked this morning fuel was still stuck up at the neck where it flattens out before going to the tank itself, I poked it with some bailing wire and air escaped past it and it went down.
upon further inspection I realize that where the aspirator line should be is a bolt threaded into the nipple.
that may be some of my filling issue,
