: vapor emmissions system

Filled up my 94 fwb the other day, highway driving, & noted it took over 23 gallons of fuel, was at the quater tank mark. Wondering if that check valve on the cannister could be on its way out. Car has 145,000 miles on it, am having similar problems like this on my 94 roadmaster sedan, same system.
