KTM 690 Fuel Filter Relocation
Kenneth Moonitz
Moving the Fuel Filter to an External Location
Are you sick and tired of that damn fuel filter replacement? Trust me, I know. I got so tired of trying to wrestle that thin out of the fuel tank, and then carefully insert the pump/fuel line back into the fuel tank without it kinking anywhere. So you know what? I went ahead and removed the quick release line (kinda strange this is on the SMC model, but maybe some people need to cut fuel to the injector more frequently than other motards?) and released it with a NAPA Gold Filter 3095. Strangely enough, the OEM fuel filter has two different sized fuel lines that meet at it. You have a ¼” line that runs to the injector, and a 5/16” fuel line that travels back to the fuel tank. Avoid those plastic union connectors, you’ll be submerging this connection in gas, so you do not want to take any chances. I ended up sweating one ¼” and 5/16” union end together and had to run new 5/16” fuel line from the tank to the connector (as the old one was not long enough). Changing/checking fuel filters is a breeze now! So many oddities KTM designed with this bike that makes things difficult to maintain… Another mod successfully added and enjoyed!
