Some smaller and older service stations has debris and sediment in their storage tanks and that sediment and debris which eventually can make its way to the injectors is pumped into the fuel tank. Residue from the rust gets into the injectors when the fuel filter is in bad shape.
The water in the fuel cause internal components to rust. Ethanol is hygroscopic thus drawing moisture from the air into the fuel. Why does fuel injector clogging happen?įuel injectors become clogged due to hydrocarbons, sediment and other elements in the fuel. In a situation like this the entire fuel system has to be cleaned. If a vehicle, watercraft, motorcycle or pleasure craft sat for an extended period with gasoline in the tank, it can be assumed that the fuel system is gummed up with bad fuel, varnish and sediment. Unfortunately on some engines this can take hours to do. If the problem moves with the injector then Bingo. Moving the suspect injector to another cylinder is one way of diagnosing the problem. If the spark plug is wet and smells like gasoline, then the injector on that cylinder is not your problem. If the spark plug is dry, then the injector does not deliver fuel to that cylinder.
