2001 Subaru Impreza Question: gas pump shuts off prematurely and often

When I pump gas the gas station pump frequently shuts off in the process. I replaced the Filler Pipe, Valve and flange nut because these parts were rusted. Cost $306. The problem persists. Did I throw $300 down the drain. What can be done to fix the problem ? -
Answer 1
It is most likely your roll over valve, which is not letting out the displaced air as you fill the tank. It may be rusted shut. -
