Good To Know
Q: Will this solenoid work for both start and stop functions? A: Yes, this shutoff solenoid manages the fuel cutoff during engine shutdown, which is its primary function. It is not a starter solenoid but works in the ignition sequence to stop the engine reliably.
Q: Can I install this solenoid myself? A: Installation is straightforward for a mechanic with basic tools, involving electrical connection and mounting. Always disconnect the battery and verify the plunger travel matches your pump before installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
