OAI Adapter Hose Lengths and Stripe Colors for '70

Years ago a friend of mine had an original OAI adapter and what we believed were the three original hoses. Can anyone validate the length and if all three hoses had the white stripe or if just two of the hoses had the white stripe?
  1. The vacuum motor hose would have a white stripe. The measured length was 23 1/4".
  2. The snorkel to the therm sensor on the bottom of the base would have a white stripe but would have been attached when the base was painted therefore would have black overspray. The measured length was 21".
  3. The shorter of the three hoses measured at 12 1/4". I believe this hose was black without the white stripe.
Anyone with an original base able to confirm? This is in reference to a '70 442 with OAI.

My car was described as a survivor when I purchased it. The OAI vacuum hoses were the colors you describe. I can't agree the lengths however as mine were all three shorter than your measurements. It's difficult to say exactly what the lengths were when viewing the originals as it's possible the ends cracked over the years, they were trimmed, and reattached. Doubt you could go wrong using your measurements though. BTW, Fusick sells the 2 white strip and black hose as a set for the '70 OAI: Item AFVH702OAI, apparently you decide the lengths.

Is the shortest of the three hoses black with or without the white stripe? This would be the one that goes from the bottom of the base to the tee (I think, hard to picture it without it right in front of me!).

I don't have the vacuum hoses pulled from the car any longer; however, I could check the replacement hoses, but that would be late tomorrow.

Assuming Fusick did their research, the shorter 2 FT has no stripes
