JYINCPED Transfer Tank Fuel Cap – Vented 2-Inch Diesel Cap for Ford, GMC, and More

Overview

The JYINCPED Transfer Tank Fuel Cap is a rugged vented cap designed for standard 2" NPT bases. It offers a compact, reliable solution for venting and sealing transfer tanks, auxiliary tanks, and mobile fuel equipment. Crafted for durability, this cap aims to support safe, controlled fueling in farm, fleet, and workshop settings.

Fitment and versatility

Designed to replace vented caps on 2" NPT male threaded bases, it works with a variety of tanks and vehicles. It suits transfer tanks, diesel tanks, fuel tanks, gas tanks, and distillate systems, including weather guard style tanks. It also accommodates trucks with 2" female thread diesel transfer tanks and is compatible with notable platforms such as Ford Ranger, Chevy, GMC Canyon, Toyota Tundra, Nissan, Jeep, Honda Ridgeline, Ram, and more.

How it vents

This cap uses a dual-direction venting approach. When loosened, it releases internal pressure to the exterior and allows air to enter, helping to prevent excessive vapor buildup and reduce the risk of a vacuum forming as fuel is drawn. This mechanism can support steadier fueling flow and safer operation during transfers.

Leak prevention and seal

With a spring-loaded mechanism and an interior gasket, the cap closes securely to minimize leaks and limit vapor venting during road use. The seal is designed to perform reliably across typical weather and road conditions, helping maintain containment without over-venting.

Ease of use

Simple operation is built in. Align the notch, push down, and twist clockwise to tighten. To vent, twist back toward the notch, push down again to release pressure, and lift the cap. This straightforward procedure supports quick fuel handling in the field.

Durability and packaging

Constructed from weather- and corrosion-resistant materials, this heavy-duty cap is built to endure demanding environments and long-term use with diesel and distillates. The package includes a removable transfer tank fuel cap for straightforward replacement in compatible systems.
