31 Vacuum line

[JohnB15632]

The vacuum line that originally cam with my Model A is plugged solid.
Any ideas how I can get this tube unplugged?
Would it be better to try to manufacture/bend a new vacuum line?

Thanks,

I believe you could run an old speedo cable in and clean some of it at least. I would try hanging it up from a wire and drip your favorite penetrating oil down into the tube. I don't remember the inside diameter of that tube, so it might be a coat hanger straightened out to do the trick, but I would at least soak it first, it may be something simple. You might also use a piece of bailing wire.

John you might find that the restriction is at one of the 90 deg bends. Spray some PB buster in it using the straw and then use some compressed air with a rubber tipped air blower. Don't point the other end at anyone you like when blowing the air.
And what Wiz said

About 1980 I bought a 1952 Studebaker Champion with a plugged fuel line. I made an adaptor to fit the end of the steel line up front, then hooked up my grease gun, and still couldn't get it to open up. The grease gun can pump over 2000 PSI.

Or try PB and a small diameter wire from each end. If you can get the PB to come out the other end then that's a start.

Put a little heat at the 90 deg bends. That may help to loosen things up

Thank you for this information. Upon further review of this part, The description state, Steel vacuum line with brass fitting that goes from the intake manifold up to the firewall. With this description, this is not the complete line required for the 31 SW. This only goes to the firewall, not up and beyond.

Thanks,
