What is the solution for a rusted fuel tank?
2 Answers
It is best to replace the fuel tank if there is internal rust. 1. Main impacts of a rusted fuel tank: Contamination of gasoline. Rust can fall into the gasoline due to road bumps, leading to clogged fuel lines and subsequently causing insufficient engine power. 2. Acid pickling and phosphating treatment: Acid pickling and phosphating treatment can be used to remove rust, oxide scale, and oil stains inside and outside the fuel tank. The four-in-one phosphating solution performs derusting, degreasing, phosphating, and passivation in the same tank, combining four processes into one. This method simplifies the process, reduces equipment needs, shortens the construction period, improves efficiency, lowers costs, and enhances working conditions.
When I find rust in the fuel tank, I first ensure safety by draining the fuel and moving it to a ventilated area, as rust can lead to fuel contamination or leakage risks. The treatment method depends on the severity of the rust. For minor rust, I use sandpaper to sand it down or spray it with a rust remover, then dry the surface after derusting and apply anti-rust paint to seal the rust layer and prevent further spread. I often do this job in my own garage, which takes one or two afternoons, and the cost is low, using just some ordinary products. However, avoid touching the important welds at the bottom of the tank. If the rust is too severe, such as holes or perforations, it's better to give up DIY and replace the tank with a new one at a professional shop. For prevention, I pay attention to using less low-quality fuel, avoid parking in damp places for long periods, and regularly inspect the fuel tank to save a lot of trouble.
