Abstract
The invention incorporates a high flow, pilot actuated pressure relief/rollover valve into a refueling vapor recovery system having a vapor vent line for recirculating vapor past the aspirator of a refueling nozzle and a nozzle seal for engaging a refueling nozzle in an airtight manner. All vapor of evaporative hydrocarbons created during the act of refueling are routed directly to an onboard storage canister.
