Vacuum Pipe "T" Broke: How to Fix?
Without replacing the entire Vacuum Pipe, how can I fix this?
Maybe drill out the "stub" still stuck in the t and find a connector at the auto parts store? |

Did the hose break or the actual connector?

No, heat shrink tubing will NOT fix this for more than about 10 minutes.
The RIGHT thing to do is replace the whole pipe. If you're not willing to do that, then there is enough left on the tee to put a larger hose on the broken fitting. Then go to a hardware store and find a reducer fitting to reduce the large hose to the small one. Use clamps on ALL joints. |

I was thinking of something like this. Drill out the existing hard "T" that broke off and glue one end into the hard "t" of the main boost line. Clamp the smaller flexible rubber hose to the other end. Just need a solid air-tight connection right?

Just get a bigger hose that will fit on the left over bit and a adaptor to small hose. Supeglue the big hose and that sucker wont go anywhere.
I used the same method on a boost signal line that didnt have a barb and no issues. I hit 20psi, i use the gorilla super glue. |

I'd be careful with those cheap white vacuum Tees from the auto parts stores. They're usually soft and shitty plastic that tears at the slightest load once they've experienced engine bay heat cycling for a little while. I agree with the above posts suggesting to use a larger hose to go on the barb, with a reducer tucked away on the harness side of the hose, away from the heat of the cooling fan blowing on it.
Alternatively, if this is an N52 car (or any e9x where that tee is simply for the exhaust flap), if you don't mind the louder exhaust note with the flapper always open, you can get two vacuum caps- one larger one to cap off that T, and another smaller one to cap off the vacuum line that runs to the rear of the car inside the harness. The effect would be no different than the Golf-Tee mod. |
