Fuel injectors are often overlooked when preventative maintenance needs to be performed. We all change oil, tires, chains, sprocket and spark plugs – but we rarely think about our fuel injectors unless a major problem occurs. Our new GB-800 Machine allows us to carry out a variety of testing procedures to fully inspect and document your injectors.  Static and multiple dynamic flow rates are taken on the injectors before and after cleaning in our heated ultrasonic bath.

Oxygen additives in racing fuel like MTBE can cause injectors to quickly build up tarnish and a sticky film on the pintle an diffuser plates. The same can be said for pump gasoline with 10-15% Ethanol when engines ran hard. The heat from the engine can cause the fuel to quickly evaporate and leave a film on the injector tips.

Fuel additives may work for some applications to clean some parts of the injector (if one remembers to add it to the tank), but how do you know if they really work if you can’t see or test the results on every injector? With the Fuel Injection Testing and Cleaning you get to see the testing results before they’re cleaned and then the results of the testing after they are cleaned.
