Installing A Fuel Filter

One of the first modifications you should make to any nitro-powered RC vehicle is installing a fuel filter. It's very easy for dirt to accumulate around the fuel tank cap, and from there find it's way into the fuel system while refilling your tank. Even a small amount of debris can be very harmful to your engine.

There are quite a few fuel filters on the market, and they come in a variety of colors and sizes. While the color doesn't matter you should make sure you get one that's the appropriate size, or larger, for your motor. You can actually go with a bigger fuel filter to increase the capacity of your fuel system to help you run a little longer, but if you are racing there may be rules against doing that. I chose this Du-Bro Fuel Filter, which is a medium sized filter.

Installing the fuel filter is easy. All you need to do is splice it into the fuel line at a point that suits you. To avoid having the tubing come loose from the filter, you should use a wire tie on each side of the filter to help secure the fuel tubing around the inlet and outlet sides of the filter. Be aware that some filters on the market are directional and must be installed in the correct direction. The Du-Bro filter I used is not one of those however.

Below is a list of fuel filters that should work well with most small block motors.
