The Necessity of an Auxiliary Fuel Tank Cap

As a long-distance traveler and avid road-tripper, I have come to understand the importance of having an auxiliary fuel tank cap. This small yet essential component has saved me from numerous inconveniences and even potential accidents on the road.

Moreover, an auxiliary fuel tank cap allows me to carry extra fuel for longer journeys without having to make frequent stops at gas stations. This is especially useful when traveling through remote areas with limited access to gas stations. It provides me with a sense of security knowing that I have enough fuel to reach my destination without any hiccups.

Additionally, some vehicles come with a smaller primary fuel tank and rely on an auxiliary tank for extended range. In such cases, having a functional and secure auxiliary fuel tank cap is crucial for maintaining proper fuel flow between both tanks.

What is an Auxiliary Fuel Tank Cap?

Before we dive into the features and factors to consider when buying an auxiliary fuel tank cap, let’s understand what it is. An auxiliary fuel tank cap is a cover that seals the opening of the auxiliary fuel tank in a vehicle. This allows for additional storage of fuel and increases the range of your vehicle.

Factors to Consider

1. Compatibility

The first and most important factor to consider when buying an auxiliary fuel tank cap is its compatibility with your vehicle’s model and make. It is crucial to check the manufacturer’s specifications or consult with a mechanic to ensure that the cap fits perfectly.

2. Material

The material of the auxiliary fuel tank cap is also essential as it affects its durability and performance. Most caps are made from plastic or metal, with each having its advantages and drawbacks. Plastic caps are lightweight and corrosion-resistant but may not withstand extreme weather conditions. On the other hand, metal caps are more durable but can be heavier.

Sometimes, certain additional features can enhance the functionality of your auxiliary fuel tank cap, such as:

– Vented Cap

A vented cap allows air to flow in and out of the auxiliary tank, preventing vacuum build-up that could hinder proper functioning.

– Gauge Reader
