Sea Foam for purge valve stuck open on Ford [SOLVED]

I have a fuel tank purge valve sticking open, and am thinking to try cleaning it before replacing it. I know seafoam is safe for rubber gaskets and other things fuel comes into contact with, so I am wondering if it will be safe for the plastics on this part. I assume so as gasoline vapor flows through, but wanted to check in. My plan is to run the engine and spray it in from the can designed to be sprayed into the air intake, as that is where this valve leads. I have a 2015 Ford Mustang, if that makes any difference. Thanks for your help!

Great question, David. Unfortunately, I don’t think Sea Foam can help with this. Most of the time, a Purge Valve fails electrically not mechanically. I wouldn’t recommend using Sea Foam Spray directly in the Purge Valve as it is part of the EVAP Emissions system and is only supposed to have fuel vapors in that system. If the EVAP system gets liquid in it, the possibility of contaminating the charcoal canister is greatly increased.

Some 2013-2018 Ford vehicles have a recall on the purge valve. It might be worth a call to your local Ford dealership.

Good question, though!
