About the Gates Saddle Tank Locking Fuel Cap Product Line

The Gates Saddle Tank Locking Fuel Cap line is designed specifically for saddle tank fuel systems requiring secure, lockable caps. This product line focuses on combining robust materials like solid brass with functional features such as fuse plugs and non-vented designs to meet safety and security standards. The 31870 part number exemplifies these qualities, making it suitable for applications where fuel security and durability are critical.

Detailed Product Description

The Gates 31870 fuel tank cap is engineered for saddle tank configurations, featuring a female thread cam type that ensures a tight and secure fit. Its solid brass construction offers resistance to corrosion and wear, extending the service life of the fuel cap in demanding environments. The non-vented design helps maintain fuel system integrity by preventing vapor escape, while the included fuse plugs provide an additional layer of safety by acting as a pressure relief mechanism. The lockable feature enhances security by restricting unauthorized access, making it suitable for commercial trucks, agricultural equipment, and other vehicles equipped with saddle tanks.

Common Applications and Problem Solving

  • Prevents fuel theft and unauthorized access with lockable design
  • Reduces risk of fuel contamination through secure sealing
  • Maintains fuel system pressure and safety with fuse plugs
  • Resists corrosion and wear in harsh operating conditions
  • Compatible with saddle tank fuel systems requiring 2.5" x 8 thread size

Installation Notes and Tips

Ensure the thread size of 2.5" x 8 matches the vehicle’s saddle tank fuel inlet before installation. The female thread cam type requires proper alignment to avoid cross-threading. Tighten the cap securely but avoid over-torquing to maintain the integrity of the fuse plugs and sealing surfaces. Regular inspection is recommended to verify the locking mechanism and fuse plugs are functioning correctly.
