THE CHARCOAL CAN PLUG ALL SORTS OF THINGS EITHER DISCONNECT OR REPL SOON,AS IT WILL CAUSE MORE DAMAGE
Can the fuel system be flushed as I have been driving with it like that since March of 2012. I am going to replace it but feel I should put some kind of flush or cleaner in my tank and run it through the system. Any advice.
Thank you.
