Sea Foam for gummed up fuel injectors [SOLVED]

I have a car with fuel injection that sat for 20 years. I have pulled the gas tank and the pump and tank are completely gummed up by varnish. I will replace the tank, pump, and sending unit, but I am wondering if I should replace the injectors or if I could use Sea Foam once I reassemble the fuel system? Please let me know. Thanks.

Good question, Jesse.

Running a high concentration of Sea Foam High Mileage (4-6 ounces per gallon of fuel) should help clean the injectors once you get it running. It may take a few treatments, but High Mileage is great for varnish.

Hope that helps and best wishes for your project!
