My dealer says the check valve basket at the base of the filler tube has collapsed, forcing the valve ball into the closed position. $190.00 for parts, labor.
I know the valve but didn't know this vehicle had it. Does anyone know what could cause this basket to collapse? Possibly my use of 10% ethanol? My owners manual advises against its use and I only use it on rare times when
87 octane regular is not available (probably 500 total miles in three years).
Thank you, Old Uncle Steve
