• Vacuum-Delay Valve

NAPA ECHLIN Vacuum Delay Valve. It is recommended to put this delay valve in the vacuum line of the GM 17113186 Vacuum-Adjustable Fuel Pressure Regulator (used for GM TBI applications) to delay how quickly the vacuum will change the fuel pressure. It helps to eliminate bogging on strong acceleration or the sudden drop of fuel pressure when backing off the accelerator quickly.
