MaySpare Fuel Shutoff Solenoid 26214 12V Direct Replacement for Stanadyne & Roosa Master — OEM Fit, 180°C Copper Coil

MaySpare Fuel Shut Off Solenoid 26214 is a 12V direct-replacement shutoff coil engineered to fit Stanadyne and Roosa Master mechanical injection pumps for many GM, Ford and John Deere applications.

This replacement solenoid restores controlled fuel shutoff for diesel engines using Stanadyne or Roosa Master injection pumps. Built with a high-temperature copper coil and designed to match OEM dimensions, it swaps into pumps listed under part numbers like RE37089 and RE62240, offering a cost-effective way to revive fuel system reliability without machining or modification.

Which engines and pump models will this solenoid work with?

The MaySpare 26214 matches the physical and electrical specifications of many Stanadyne and Roosa Master shutoff coils. It is compatible with Stanadyne DB, JDB, DC, JDC, DBO, DM2, DM4, DB2 and DB4 series pumps and fits mechanical pumps used on GM and Ford V8 diesel engines.

• GM mechanical pumps: 4.3L, 5.7L, 6.2L, 6.5L
• Ford mechanical pumps: 6.9L and 7.3L
• Also used on applications that reference RE37089, RE62240, AR48219, AR51796, AR90340

How does this solenoid match OEM performance and quality?

MaySpare designed the coil to OEM dimensions and electrical spec (12VDC) so it installs like the original part. The winding uses copper rated to 180°C for improved heat tolerance and consistent magnetic pull, helping provide dependable shutoff action under normal operating conditions.

• 12VDC coil matching original electrical requirements
• 180°C-rated copper winding for thermal durability
• Form, fit and function designed to be a direct swap for the listed part numbers

What should you expect during installation and operation?

Installation is straightforward for technicians familiar with mechanical injection pumps: remove the old solenoid, transfer any mounting hardware if needed, and secure the new coil in place. Once installed, the solenoid responds to the pump’s control circuit to cut fuel flow when de-energized and allow fuel when energized, restoring normal engine shutdown behavior.

• Direct replacement—no machining required in most cases
• Standard 12V wiring connections for pump control circuits
• Compatible with both Stanadyne and Roosa Master mounting arrangements

What warranty and quality assurances come with this part?

MaySpare supplies this replacement solenoid with a six-month limited warranty to cover manufacturing defects and early failures. The part is quality-checked to ensure it meets mechanical and electrical tolerances expected for fuel shutoff coils used in diesel injection systems.

• Six-month warranty against defects
• Manufacturing inspections for fit and electrical continuity
• Sold as a high-quality aftermarket direct replacement

Who is this for: This MaySpare solenoid is aimed at diesel mechanics, farm equipment technicians, fleet maintenance crews and DIY enthusiasts who need a cost-effective, reliable replacement for worn or failed shutoff coils on Stanadyne and Roosa Master mechanical injection pumps. It suits owners of GM and Ford diesel vehicles and equipment that reference the listed replacement numbers and require a 12V direct-fit solenoid to restore proper fuel shutoff and engine shutdown control.
