1989 Bronco Vacuum lines

Post by solgraphics » Wed Aug 20, 2008 9:58 pm

Hi, first off let me apologize if I spelled vacuum wrong. I have a 89 Bronco that I need to take to emissions. I'm affraid that it wont pass because I just purchased it a few months ago and the vacuum lines are kind of... well plugged with bolts. Can anyone send me a photo or diagramn of a vacuum system? I just need to get the top part done before I go in. It's a 1989 Bronco with a 302 FI engine. Please help! I looked for other posting on here regarding this, but could not find anything. My searches resulted in over 3,000 results.

Hey John, welcome aboard! Sorry it's taken so long to get back to you. Probably because for the most part, we're owners of Early Broncos ('66-'77 variety) and though some of us have Big Broncos, they don't come up in conversation as much. Hence the lack of discussions on vacuum routing for your year.
There is a good source of vacuum (I'm pretty sure you spelled it correctly) diagrams on one of the auto-parts stores websites. I'm thinking AutoZone maybe? I've got it saved somewhere and will try to find it for you. I've used it many times to reference my '79. I'm pretty sure they have them for most years.

I'll be back...

although you're perfectly welcome here, you might have more luck finding knowledge about your year on the broncozone forum.


Good luck.
