Hey SMB forum members,
I briefly mentioned this issue in my "build thread," but thought it might be useful to create a separate thread for this issue by itself.
Basically, the issue is that the gas pump auto shutoff triggers successfully, but a couple ounces of gas will splash out of the fill neck after the shutoff is triggered. Sometimes using the slower fill setting on the pump helps, but sometimes it still splashes. This happens at every single gas station I go to, so it's something with the van, not with the pump.
I started experiencing this issue after our van was converted at UJOR CO (our van's OEM tank was plastic, so a new Dorman tank was installed, instead of cutting down the OEM tank). I'm currently working with Justin to figure out what the issue might be, and he thinks he may have a solution. But in the mean time, I figured I'd see if you folks had any ideas!
Video of the issue occurring:
At first I thought the issue was a kinked rubber fill hose (the part that connects between the metal filler neck and the inlet on the gas tank). However, the issue persists even after I removed the kink from the hose.
Justin initially suggested that the new rollover valve he installed might be faulty, but now he thinks he might have installed "too big of vent valves." I'm not 100% familiar with the gas tank plumbing, but I guess he's referring to the check valve that relieves pressure buildup in the gas tank to the charcoal canister? I'm having a hard time figuring out how that might cause the symptoms I'm seeing, so if it makes sense to anybody here I'm certainly all ears.
