Hold vacuum to the distributor's advance diaphragm with the Standard Ignition Distributor Vacuum Advance Check Valve (DCV1). This one-way check valve drops in as a direct-fit replacement across a broad list of AMC and Ford applications, including the 1978 AMC AMX, 1977 AMC Hornet, 1994-1997 Ford Aspire, 1992-1997 Ford Crown Victoria, 1979-1997 Ford Mustang and many more — see the Buyer's Guide tab for the full list.
Installed in the vacuum line, the valve lets vacuum travel to the distributor's vacuum advance unit while limiting backflow, helping maintain advance as engine vacuum changes. If a leaking or stuck check valve is the cause of lost vacuum advance, hesitation, or sluggish throttle response, this replaces it — diagnose the vacuum circuit before installing.
Emission-focused manufacturing: built by a global emission-component maker with quality control maintained from componentry through the finished valve.
Backed by R&D: decades of industry-leading research and development aimed at the technician's needs.
Two hose connectors: ties into the vacuum line through two ports.
Contents: one check valve.
Country of origin: United States. Manufacturer part number DCV1.

What are signs this valve may need replacing?
Loss of vacuum advance, hesitation, or poor throttle response can be signs, but these have other causes. Test the vacuum circuit first and replace this valve only if it is the fault.
