Aluminum Fuel Tanks on Semi Trucks

Your aluminum fuel tank is crucial to your truck, storing the needed diesel fuel for long hauls. Aluminum is used as the material of choice for manufacturing fuel tanks due to its superior characteristics:

Lightweight Design: Aluminum tanks keep your truck light, thus optimizing fuel efficiency and payloads

Natural Rust Protection: The metal develops a protective layer of oxides that protects against rusting and corrosion

Durability: Engineered to withstand long-haul trucking conditions and fluctuating weather climates

The Problems Faced by Aluminum Fuel Tanks

Despite all these benefits, road conditions are a serious hazard to aluminum fuel tanks. They are constantly exposed to:

• Diesel fuel splashes during refueling
• Road salt and chemicals
• Extreme weather conditions
• Environmental pollutants

These factors can create a perfect storm that compromises the integrity of your tanks. These tanks often become covered in diesel fuel, corrosion, and the weather just really takes a beating on them.

The Consequences of Neglected Fuel Tanks

The formation of rust and dirt not only deteriorates the look of your truck but also creates numerous serious problems. Fuel efficiency can be impaired with surface degradation because impurities disrupt the optimal performance of the tank. A weakened tank frame will lead to future danger in the vehicle, jeopardizing the driver’s safety and the truck. Secondly, failing to have your truck cleaned and serviced at regular intervals decreases its resale value and will make it less attractive to potential customers. These problems will also become more expensive maintenance down the road, which will not only hurt your bottom line, but also the health of your truck if they are not addressed.

In order to protect your investment and deliver top performance on those vital miles down the line, keep your aluminum fuel tanks clean and well-maintained on a regular basis.

Essential Tools and Safety Equipment for Cleaning Aluminum Fuel Tanks

The right equipment is needed to properly clean out your aluminum semi truck fuel tanks. Here is what you will need:

Essential Tools:

• Garden hose with specialized nozzle (like the Snap-On model)
• Filtered water (Evian or similar)
• Nano Skin Acid Wash cleaner
• Spray applicator for the acid wash

Safety Equipment:

• Protective gloves
• Safety glasses or shades
• Long-sleeve clothing

Filtered water is the magic bullet when it comes to cleaning aluminum tanks. Tap water has minerals in it that drop on your tank’s surface and can form new corrosion areas. Filtered water prevents deposits from forming and gets your finish cleaner.

Your nozzle choice matters, a pro-level nozzle like Snap-On provides the perfect pressure and coverage for initial rinse and chemical application. These nozzles can cost a little (approximately $600), but it is well worth it to achieve pro-level results.

Don’t forget to put on your protective gear before beginning the cleaning process. Acid wash carries a characteristic chemical smell and is dangerous to your skin or eyes if it comes into contact with them.
