Multiquip 37378 Lift Pump Solenoid

The Multiquip 37378 Lift Pump Solenoid is a genuine OEM replacement designed for the PS, SP, and CS pavement saw series, including models PS403020, PS403030, SP403020, SP403026, CS403016, CS403020. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory. The 37378 is a direct-fit replacement that installs in place of the original solenoid without modification to the fuel system or surrounding components. If your saw is experiencing starting issues or fuel delivery problems, this solenoid is the correct OEM solution to restore full operation.

Key Features

• Genuine OEM Electrical Specification — Matched to the correct voltage and actuation response for the lift pump circuit on Multiquip pavement saws, ensuring consistent fuel delivery on every start cycle.
• Direct-Fit Replacement — The 37378 connects to the existing wiring harness and mounting position, dropping in exactly where the original solenoid was installed.
• Broad Saw Series Compatibility — Fits the PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 pavement saw models.
• Restored Fuel System Function — A functioning lift pump solenoid keeps fuel flowing to the engine on demand; a failed solenoid can result in hard starts, stalling, or a saw that won't run at all.
• Fuel System Safety Compliance — As a key component in the fuel delivery circuit, using the correct OEM solenoid ensures the system operates within its designed parameters and shuts off fuel flow properly when the machine is not running.

The lift pump solenoid controls the flow of fuel from the tank to the engine's lift pump, acting as an electrically operated valve that opens when the ignition is engaged and closes when the machine shuts down. On pavement saws like the PS, SP, and CS series, this component is critical for reliable starting and steady engine operation during cutting work. When the solenoid fails — whether due to a burned coil, corrosion, or mechanical wear — the engine may crank without starting, lose power under load, or shut off unexpectedly during a cut.
