Does anyone know if any of these chemicals cause any deterioration on gaskets or seals in auto fuel pumps, etc. ?
The vehicles that are old enough to have natural rubber are probably old enough that the gaskets will need replacement and should be (or should have been) replaced with proper materials.
Also remember even if your vehicle has non compatible gaskets acetone will not instantly eat them away, it generally takes years to occur, also in the few cases that is has happened generally the gasket that goes was already on its last legs so to speak.
My personal experience has been that I have not had any unusual gasket or pump failures and I have used acetone and other additives for some time.
