Fuel Safe ILVV06 In Line AN #6 Male to AN #6 Male Spring Loaded Check Valve Union Adapter Fitting

Fuel Safe's in-line check valve with an integrated spring. Check valves are normally sprung or have a hinged trap door, keeping constant pressure in one direction, allowing fluid to travel one way through the valve. Ideal to prevent drain back after the fuel pump is turned off, or when dual pumps are used and both pumps may not run simultaneously. For installation after the fuel pump but before the fuel pressure regulator.

The top portion of this valve is the same as ITVV06S. So if you need replacement parts, you can simply buy the ITVV06S check valve.
