I have removed the front and rear tanks of my 1994 F250 7.3 IDI for cleaning and sending unit replacement . I will use some degreasining cleaner like Purple Power and a pressure washer (or spray car wash) to clean them . If I see rust should I also then use muriatic acid and water solution (fill tank and less it sit for a couple of days to dissolve the rust ? ) . Any suggestions on tank cleaning procedures are appreciated. - Thanks
