Vacuum Advance Tube Support

Re: Vacuum Advance Tube Support

According to an NCRS judge, my vacuum advance tube is original for my 350/350. I ought to send pictures and dimensions to the 70 Corvette Registry.

Not the same judge who told you there should be a clip I hope.

I did put the spec's on the registry a few years ago. A tube supplier has the specs for fab but lacks the double bump tube. I'd like to see a pic of yours if you don't mind send it to me or post.... Here's the spec and an original sent for my use by a member

Patrick... I had to take a double look myself. What you see as foam on the TCS soleniod in Greg's photo is actually tha short rubber hose that in my photo has a white stripe.

All 3 ports(nipples), on the 70 solenoid are used, so none would have a foam filter as the 71 piece I noticed in your great collection of photo's .

OK, you're correct.
I should remember what's on my 70 Cutlass, as it's similar to the 70 Corvette.
