Yesterday I took the sending unit out of my 74 Dart gas tank to install in a new tank. I tried blowing through it and got very little air flow. Pipe cleaner in the tube cleaned out a little of the dried up gunk, and then I tried heavy duty copper wire. All I did was jamb the gunk further down and now no air flow. How do you clean out the gunk? New units are $88. Anybody ever used high pressure air hose or something corrosive? Suggestions.

just the pickup? ya, i soaked in degreaser, then clamped up my oxy line (i blow glass) and put about 30 psi in it... and wow was it gross commin out.. so clean now... hope that helps

Never, ever put pure O2 in a pipe that isn't spotlessly clean. Boom!

I had the filter sock collapse on me once and starve the engine for fuel. I pulled the fuel inlet hose off the pump, took off the gas cap and blew air into the tank. I lost about a quart of gas, but I wasn't starving the engine any more.

Too many people who were born on third base actually believe they've hit a triple.

Randy, cap off one end and dump some solvent (maybe B-12 or Beeman's) into the pickup tube for a good soak. Empty it later and then blow a little compressed air through the end opposite from the one you jambed it up.

Thanks for the replies. The compressed air did the trick. I have a new sock and float. Before I reinstall the sending unit, I wonder if the same varnish/crap is clogging my line from the tank to the engine. Anybody ever had a clog in the fuel line under the body of the car?
