I noticed the other day my vacuum hose ( german fabric wrapped hose) that runs from booster check valve to the rear of the intake collapses slightly when all that V12 heat warms up the engine bay and is under vacuum.
If i remember correctly, I used some correct sized hose I had in the shop when I rebuilt the master, but didn't source anything special. Clearly I should get something more reinforced.... but car is in my storage facility now..
Does anyone know the ID of the vacuum tube for the Male fitting of the manifold so I can get the right size? or have and good sources for something correct and functional? mine works fine but want to play it safe and replace it.

Hi Michael,
I think it's the same size as on the 250s and I have an engine on the work stand at the moment that I can measure. Text me on my phone tomorrow midday to remind me to measure it for you.

Greetings... Not sure if they are the same but mine (Series 1) measures 13mm.

Re: Intake manifold to booster vacuum hose ID
I've heard of both 13mm ID and 14mm ID hoses, possibly a 13mm hose could fit onto a 14mm diameter 'end' with a bit of persuasion...

I used 15mm reinforced cloth covered wire hose ordered from BelMetric Automotive (belmetric.com) on my Daytona last year to redo the brake vacuum hoses and it fit perfectly. If its too small its hard to persuade the wire reinforced material. Good Luck. Drew

Re: Intake manifold to booster vacuum hose ID
Michael, for both my Daytona and the GTC, I used Aeroquip FC647-AN 8. As you may know, the AN represents fractions of "16", so, an AN 8 is 8/16" or 1/2" or 13+mm. It will be a fight, but some grease + a heat gun got 'em on. I may have a few extra feet, so feel free to email me and if you're interested I'll check tonite. Otherwise I got mine from Eaton (800-578-7093) or Murdoch (330-535-7105). At Murdoch, I dealt with a lady named Lynn (330-535-7109).
