1. 2017-1987= 30 years, you know? Not the ethanol, just old rubber.
2. "New gas"/ethanol was not in it long. Over the long haul it will eat non ethanol compatible rubber including carb internals.
3. Ethanol can not sit 2 months. It will absorb water. Cause big problems. Motor won't run.
4. Treat gas if there is a treatment. Some treatments will add to the problem. Be careful. Most people doubt that these additives really work.
5. The pouring out gas at carb base could be a different issue. Stuck float, bolts loose, worn shafts....or it could be ethanol deterioration like; accelerator pump skirt, needle valve rubber, gaskets, etc.
6. Change all fuel filters and be sure their filaments are E safe.
7. Empty all fuel from tank and start over.
8. Look up "phase separation".
9. Our older trucks are not set up for this stuff. Maybe a water separator could be used after fuel pump. Haven't studied that idea. They use them on boat motors.
10. The E fuel will release certain types of fuel tank build ups that were not released before. This will cause big time clogging until all is gone.
11. Bottom line, read the pump gas signs. Try not to use that E crap on older classic vehicles.
12. Thank goodness that no O rings were used on our older trucks. The fuel pump has a rubber diaphragm!!!
