Will definitely try the rag approach. I’ll remove and clean all the hoses near the fuel fill. re your comment about backfires. It only happens right before it quits. Usually two quick shots. So I’m betting the pressure issue is suddenly making it run rich just before it sputters and dies.
I think the issue is to much pressure. I popped the fuel cap, reinstalled and she fired right about at 3/4 full. Running great. Could it be something in here?
ASFAIK, the smog gear is all still hooked up properly. Sight glass is a bit less than half full. The carb jet spray is strong so I don’t think it’s the fuel pump or filter. Changed fuel cap but same issue quitting at 3/4 full.
2F with OEM fuel system (but added the smog crap for California). I have been using a Dakota Digital for the past 5 years.
Symptoms:
1) With full tank, fires up and runs smooth. When the gauge shows 3/4’s I get back firing and then she’ll quit. Add fuel to the tank from spare can and starter...
