Overview

The Taesayl 2 1/4” Diesel Fuel Cap is engineered for reliability on the road. Crafted from aluminum and designed with a practical non‑locking style, it aims to restore OEM-like function while keeping refueling straightforward. This isn’t a guarantee of results, but a robust option for drivers who value fit, durability, and peace of mind during long hauls.

Key Fit and Compatibility

Designed as a direct replacement for a wide range of heavy‑duty trucks, this cap aligns with a 2 1/4" diameter and a 2 5/16" cross‑threaded filler neck. It fits International DuraStar models from the 4100 through the 4900 series and TopKick configurations, along with Ford F600, F650, F700, F750, and C6500 lines. This broad compatibility helps streamline part choices for mixed fleets or multi‑brand operation.

  • 2 1/4" diameter cap
  • 2 5/16" cross‑threaded filler neck
  • 2 1/4" cross‑threaded cap
  • 11.5 TPI NPSH

Durable Aluminum Construction and Sealing

Built from aluminum with OEM‑like standards, the cap emphasizes durability, stable performance, and resistance to common wear. The sealing design helps curb fuel evaporation under everyday driving conditions, contributing to steadier fuel levels and less downtime for refills.

  • Aluminum body for durability and reliability
  • Durable, factory‑grade construction
  • Effective sealing to minimize evaporation

Safe, Convenient, and Easy to Install

With a stainless steel safety chain included, the cap is less likely to be misplaced on rough roads, reducing the need to recheck fuel caps after every stop. The non‑locking design supports quick refueling cycles, while the overall form matches the original fit for a familiar feel.

  • Non‑locking design for easy access
  • Stainless steel safety chain helps prevent loss
  • Direct replacement with identical functionality
