I needed to repair the pipe connector on the gas tank as it was leaking so I pulled the tank. I decided to clean out the tank while it was out. I had done the muriatic acid followed by baking soda flush with success many years ago but I wanted to avoid working with the toxic acid this time around. I read about the variety of ways that a tank could be cleaned and decided on using phosphoric acid. When I went to the local Canadian Tire store I saw a container of Krud Kutter and I remembered that it was as one of the items you could use to clean out a gas tank(mostly used for preparing surfaces for paint) so I bought that instead of the phosphoric acid.
So I sloshed the container of Krud Kutter around in the tank and let it sit for awhile. The instructions said to rinse out after use "BUT" if the surface was unpainted you did not have to rinse because the chemical would dry and seal to the surface so that is what I did. I filled the tank with gas and the car ran great for a fast run on the highway. However the next time I went to start the car it wouldn't idle and kept stalling out. I checked the new fuel filter and it was half full of a black liquid and black flakes.....hopefully the filter got all the crap before it got to the carbs? I installed a new filter but am stll getting the hesitation,rough idle, and stalling.
There is only a couple gallons in the tank and I was thinking instead of pulling the tank(which I will do if I have to) I could possibly drain the gas out of the tank in the car and flush out the tank with??? maybe denatured alcohol? Any ideas?
