Can I fill Sea Foam Marine PRO into an empty fuel/water separator as a concentrated dose to clean fuel system and injectors?

Thanks for the question, Ben! The concentrated approach you are describing is a great way to clean the fuel system and injectors.

Use a 1:2 ratio of Sea Foam Marine PRO to fuel (1 part Marine PRO to 2 parts fuel).

Here are a few step-by-step resources:
