3935649 New 12V Fuel Shut Off Solenoid Valve
The 3935649 model from BUYMACHINERYPARTS is a 12V solenoid valve designed for diesel engine fuel shutoff ahead of the Bosch P7100 pump. It features a 3-pin connector and 3 inch mounting bolt spacing, aligning with many Cummins 4B/6B/6C 5.9L and 8.3L engines. Material quality and electrical compatibility are pitched toward easy retrofit in older builds or replacement scenarios. Consider confirming the exact pump assembly and mounting pattern on your unit before ordering to ensure a precise fit.
GLOCRORET 12V Fuel Shut Off Solenoid Valve
GLOCRORET’s 3935649-compatible solenoid emphasizes interchangeability with Cummins 4B/6B/6C 5.9L & 8.3L engines and Bosch P7100 pumps. With multiple cross-reference numbers (VW, Ford, Woodward), this valve aims to simplify replacements across a fleet that includes Komatsu 8.3L variants. It offers 12V operation and 3-pin connectivity, but users should verify mounting spacing and pump compatibility on their specific engine before purchase.
846639 Fuel Shut-Off Solenoid Valve
The 846639 from eeaee is designed to fit a broad range of lawn and garden engines, including John Deere and Husqvarna models, along with Briggs & Stratton and Craftsman variants. It’s presented as easy to install and helps prevent fuel drain when the ignition is off. Before buying, verify your model number and ensure the 3-inch mounting bolt spacing and 12V coil match your system’s wiring and pump configuration.
Fuel Shut Off Solenoid Valve 3035344 3054291 for Cummins
APIELE’s valve covers Cummins NTA855 and N14 M11 K38 K50 lines with multiple part numbers (3035344, 3054291, 3018453, AR5499) and a 12V DC coil. It includes an O-ring for sealing and notes a steel insert to prevent leaks. This model is positioned for heavy-duty diesel installations where a precise fit and durable seals are crucial, especially in older Cummins configurations. Confirm the exact pump and engine model to ensure compatibility.
X AUTOHAUX Fuel Cut-off Shut Off Solenoid Valve 12V
X AUTOHAUX offers a versatile 12V solenoid intended to replace several part numbers (7167-620C, 7W6249, 17/105201, etc.) across Perkins, Mitsubishi, and Caterpillar equipment. This makes it a practical option for mixed fleets or aftermarket work where matching a single part number isn’t feasible. Check that the mounting spacing, connector type, and pump compatibility align with your machine before purchasing.
Fuel Shut Off Solenoid Valve AR5499 3018453 3035344 3054291
API-SOLENOID’s AR5499 series focuses on Cummins NTA855 and N14 M11 K38 K50 engines, offering 24V variants that extend beyond the 12V options in the list. The lineup emphasizes top-tier manufacturing and durability for demanding diesel environments, with multiple compatible part numbers to reduce sourcing hurdles. When selecting, verify voltage requirements and the sequence of installation with your electrical system and pump model.
Buying Guide: Key Purchase Considerations
- Voltage and electrical connections: Ensure the solenoid matches the system’s voltage (12V is common) and connector type (3-pin, spade, etc.). A mismatch can prevent actuation or cause wiring damage.
- Mounting geometry: Check bolt spacing (often around 3 inches) and overall dimensions to ensure a proper fit on the pump housing or mounting flange.
- Pump compatibility: Many solenoids are designed for particular fuel pumps (for example Bosch P7100) or engine families (Cummins 4B/6B/6C, Komatsu, Perkins). Verify exact model numbers and cross-references.
- Materials and seals: Look for robust O-rings, brass or stainless components, and corrosion resistance to withstand fuel exposure and temperature variations.
- Warranty and return policy: Choose a vendor with a clear warranty and straightforward return options if the part does not fit or fails prematurely.
- Installation considerations: Some solenoids require draining fuel, disconnecting lines, or priming after installation. Ensure you have proper safety procedures and tools.
- Cross-compatibility versus dedicated fit: Some models are marketed as interchangeable across brands; confirm vehicle-specific compatibility to avoid leaks or non-operation.
- Long-term reliability: For critical engines and equipment, select a part from a reputable manufacturer with documented durability and field use data.
In selecting a shut off solenoid, users should balance exact fit with broader compatibility, especially in mixed fleets or older equipment where a perfect match may be difficult. Prioritize verified part numbers, mounting specs, and voltage compatibility to minimize installation challenges and service interruptions.
