Will Sea Foam unstick a stuck open fuel injector? [SOLVED]

Hi John,

If dirt, gum, or varnish residues are causing the fuel injector to stick open, then yes. Sea Foam in a strong concentration will help clean that fuel injector and help it work properly again. Don’t be afraid to use a full can of Sea Foam (or two) in a low amount of fuel (1-2 gallons). High Mileage would be a really great choice as it’s made for tough residues.

Not an answer but would having high concentration damage the fuel filter/pump. I have an aftermarket DW300C lpfp. Guess the point is will it damage out be too much for the fuel pump or whatever?

Good question. A high concentration is safe in a fuel pump. Sea Foam Motor Treatment is made with 100% safe petroleum cleaning and lubricating ingredients. It doesn’t have any harsh chemicals that could damage a fuel pump.
