Re: 85 Chevy K30, 454, dual gas tanks, carb. It's a great truck.
Hello All,
I just getting back to starting it up. The last time I started it was about 10 years ago. I remember I dumped 5 gallons of gas in one of the tanks, new battery and vroom.
I assume there is (was) some gas in there still. Maybe water ... who knows. So, I tried to suck gas out of the tank via the hose on the carb with a mityvac. Pulled a vacuum but didn't a drop of gas through the line. Again, I assume it must be the fuel valve is all gummed up. I have no idea.
I just got under there and tapped on the bottom of the tanks and they sound empty. I pulled the filler hoses off the tanks and stuck a hose down there and came up dry.
Can that 5 gallon of gas evaporate in 10 years? I thought there would have to be something in there.
???
So, my question is what is the best way to clean the tanks; without taking the tanks out of the truck? Can i dump some kind of cleaner in there to loosen any gum in there. Marvel mystery oil maybe?
I just want to maybe just dump a cleaner in there and let it sit for a week and then get that hose back in there and suck out as much as possible and then mity-vac the rest of it out.
That tank looks like its about 5 feet long and it sitting nose down on a little bit of a hill.
I'd really appreciate some ideas on how to deal with that.
Thanks a lot
