im trying to get the gas tank out of my 1940 ford coupe. it is full of garbage and has been clogging my fuel line.i want to clean it out real good. i have the 2 bolts out, the sending unit unhooked, the filler neck off. and the main line to the fuel pump off. also i have the exhaust out of the way.i can get it to move back and forth but it does not want to come down. whats the secret to getting these things out? anyone????? thanks, c. conners.
