"Snap" Fuel Nozzle Check Valve

Spring loaded "snap" check valve replaces filter element on fuel nozzle.  Valve opens when fuel pump pressure reaches 130 PSI and "snaps" shut when fuel pressure drops below 130 PSI.  Stops "smokey" burners at start up and eliminates "shut down" after burn.

• Reduces nozzle fouling caused by residual fuel in orifice
• Easy field installation in standard fuel nozzles
• Reduces soot build up in coil
