We are cleaning a gel out of a fuel tank that is dissolved by Acetone. We want to neutralize the acetone by adding water to achieve a mix of 50/50 so that (PERHAPS) the acetone will not damage rubber / plastic compounds in the fuel system.
We have an electric fuel pump we are going to use to get the acetone and water out and we need to make sure we don't damage it. THEN there are the two brand new mercruiser marine fuel pumps, fuel filter and carburetor seals we don't want to damage. We CAN add more water than a 50/ mix as well.
We know we can't get all the contents of the tank out and so we want to make sure any remaining acetone will not be of a concentration to ruin the fuel system components. By the way... this is for a famous movie director Roman Coppola.
