Standard Ignition Fuel Pump Relay P/N:RY-726
Keep the fuel pump circuit switching reliably with the Standard Ignition Fuel Pump Relay RY-305. This relay is an electrically operated switch that delivers battery power to the electric fuel pump circuit on command. It drops in as a direct-fit replacement for the listed applications: the 1994-1997 Ford Aspire and the 2000-2001 Mazda MPV — see the Buyer's Guide tab for engine-level fitment.
Signs the original relay may need replacing include a no-start, intermittent stalling, or a fuel pump that doesn't prime. If a failed fuel pump relay is the cause, this replaces it — diagnose the circuit first, since these symptoms can have other causes.
