Hi
We have several people reporting they have used RPM on aluminum carbs ( AVS-AFB) to prevent that white corrosion on aluminum.




My great uncle bought a V8 Ford in 1938. We don't drive it very often, and the inside of the fuel pump filled up with that white corrosion stuff. It's an aluminum pump that comes apart into two halves with a rubber diaphram in between. Could I use RPM inside the fuel pump?

Is RPM fuel resistant? (I'm guessing so if they're using it on carbs, but maybe they're only using it on the outside?)
