Hi all,
So after 5 years of not being able to work on my car I'm finally back at it. My problem is I don't have the 19mm vacuum hose that runs from the decel valve to the "Y" fitting near the airbox.? I haven't been able to find it anywhere online or at local auto stores. Auto store employees look at me like I'm an alien and claim that it doesn't exist. (IMG:style_emoticons/default/confused24.gif) So for those of you that have sourced this unicorn hose could you please share where the secret stash is? (or an alternative) Thanks kindly. |

Auto Atlanta has the cloth wrapped ones which look OEM. Call them.
If you don’t care about that, McMaster Carr carries metric sized hose. They are located near me so I have it good for any random metric item I need. If you have to ship it gets more expensive. |

19.05mm = .750inches so a 3/4" line should work

I have a stash of just about every size of German braided hose at PMB, high pressure and rated for fuel, oil, and ethanol.
Stated as 18mm not 19 but is interchangeable in that application and with 3/4" hose. It is pricy for hose at near $20 a foot, but its a lot tougher than 3/4" Duralast from autozone and it looks correct. I can get it in 25mm too for 911 / 914-6 vent hose but that is twice the cost. |
