PREVENT GAS OVERFLOW AT THE PUMP DURING REFUELING!
Perko Brand Inlet Check Valves (ICVs) are used to help prevent wellback (the reverse flow of fuel out the fill after refueling is completed) and spit back.
These normally closed valves are opened by the presence of fuel running down the fill pipe during refueling.
These valves are designed for use with plastic or metal tanks.
The In-Pipe IVC fits inside the fuel hose itself.
