A fuel shut off solenoid (also called an engine stop or shutdown solenoid) cuts or holds fuel delivery so the engine can be stopped electrically and stays off when keyed down. On diesel equipment—skid steers, excavators, generators, and farm machines—a failed solenoid often means the engine will not shut down cleanly, will not stay running, or will not start because the fuel rack never opens.
This collection gathers aftermarket fuel shut off solenoid and stop-solenoid replacements sold by DELEYAPARS. Listings are built around OEM part numbers and coil voltage (commonly 12V or 24V). Examples that appear on qs-ys.com product titles include SA-3725-12, 17208-60015, 6691498 / 6691313, AM882277, 3991625, 155-4652, 3355427, and related cross references as printed on each page. Use those numbers for compatibility—not as proof of factory OEM supply.
Before you order:
- Match the OEM part number on the old solenoid or in the parts catalog.
- Confirm coil voltage (12V vs 24V).
- Compare connector style, mounting thread or flange, and pull/hold configuration against photos.
- Treat machine-brand wording on titles as application context only.
DELEYAPARS parts are aftermarket compatible replacements, not factory-original OEM. Ships from Lucheng, Wenzhou, Zhejiang, China, with US buyers as a primary audience for part-number orders. Contact: deleyapars@gmail.com · WhatsApp +86 157 2689 6547.
How to find the solenoid and test it before you order
Most no-start or no-shutdown complaints are not automatic proof the coil is bad. Confirm battery and grounds, find the stop solenoid on the injection pump or shutoff valve (not the starter), and check for voltage at the connector when Run or Stop is commanded. A multimeter can show an open or shorted coil; it will not fix a stuck linkage.
Educational walkthrough (symptoms, checks, when to replace): When do you need to replace a fuel shut-off / stop solenoid? For a meter-focused tutorial, see the fuel shut-off solenoid diagnostic guide.
Can I test a fuel shut off solenoid with a multimeter?
Yes, as a coil and voltage check. Measure commanded voltage at the plug, then coil resistance with power off. Infinite resistance usually means an open winding; near-zero often means a short. Always match 12V vs 24V on the replacement.
Where is a fuel shut off / stop solenoid located?
Typically on the injection pump, fuel rack, or a remote shutoff valve. Use the OEM part stamp and the machine parts diagram—machine brand alone is not enough for fitment.
FAQ
What is a fuel shut off solenoid used for?
It electrically opens or closes fuel delivery so the engine can start and shut down on command. It is not an ignition switch.
How do I know if I need 12V or 24V?
Read the stamp on the old coil or the machine electrical system voltage. Ordering the wrong voltage is a common cause of immediate failure or no-operate.
Are these genuine OEM solenoids?
No. They are aftermarket compatible replacements matched by OEM part number where listed.
Can I pick a solenoid by machine brand alone?
Brand helps browse, but the OEM part number plus voltage and connector decide fit. Send photos if the stamp is unreadable.
Do you ship to the United States?
Yes. Orders are fulfilled from Wenzhou, China, through qs-ys.com. Confirm shipping options at checkout or ask support with your destination and quantity.
