A rusty fuel tank can hit you where it hurts. Interior rust can sneak under the radar – it’s often quiet – and it’s immensely detrimental.

We have a product to clean up a rusty tank – but we’ll get to that later.

First, we’ll address warning signs and prevention methods.

What kinds of tanks are at risk?

Any tank in any vehicle. Time and wear can cause any tank to become porous and damp – from those in diesel vehicles to heavier duty tanks made of GFRP composites. Any dirt is bad for your engine, and it’s impossible not to keep it all out, no matter how meticulously you care for your vehicle.

How do I know my fuel filter is plugged?

A sputtery engine when you’re driving highway speeds or hit the accelerator. Why? Because the rust is prohibiting the necessary amount of fuel from traveling through the filter. Your car will still run – but it won’t run well, and this is a dangerous problem to ignore. When your filter is clogged, the dirt that used to get filtered out goes into your fuel injectors, which are very costly to replace.

This seems like a common problem, how can I prevent it?

Paying attention and consistent maintenance. It’s very common, and replacing your filter is often a cheap fix. Your owner’s manual will have specific guidelines regarding the optimal time to change your fuel filter. Typically, the timeline is between 20,000 and 40,000 miles.

My tank is rusty. How do I get rid of it?

That’s where the WAGNER Tank Sealing set comes in. We have multiple tank sealing products aimed to eliminate rust, keep it away and have your tank looking – and your vehicle running – like new. The gist: installing a protective “inner tank.” The products work for plastic, sheet metal and aluminum tanks. You can apply the tank sealing measures after you’ve experienced rust, or beforehand as a preventative sealing measure. Both are long-term solutions.

When you’re in deep – the WAGNER phosphating converter stops rust immediately while repairing the corroded areas.
