Speaking of the rubber vacuum tee...where can I find a replacement? Mine is cracked and I don't want to have a vacuum leak.

I checked the dealership and they sell the two tubes and the tee as a set. $25...little pricey for only needing the T. Autozone and Pep Boys don't carry anything remotely close to what I need.

Until I find a replacement, how bad is it to run with the cracked on in place?

Here'* a pic of the tee:



(excuse the crappy pic - my co-worker used his camera phone)

I talked to Magnuson and 3800 Superchargers and both companies indicated there is no such thing as a replacement fitting.

Anyone have a part number for this fitting? Maybe that'* a better way to attack this.

I stand corrected. This isn't coming off the supercharger. Rather, it'* coming out of the lower intake manifold.

You can buy a plastic T at some place like autozone, then some short vacuum fittings and make your own, or get some Ts from Ed Morad.

Temporary you can do like I did until I got new ones, wrap some electrical tape around it.

you can order the entire vac line (with fitting) for around $20 from the dealer.

Ya, the vacuum line with the fitting is $25 at the local Pontiac dealer. I'll head over there during lunch and pick it up. I'd rather not rig it if I can have brand new for $25.

I found another fitting that'* cracked. This fitting is integrated into the 1/4" tubing that wraps around the firewall. Is this a dealer only part or is there a cleaver way to work around this cracked fitting? Here'* a pic:



I can only imagine what the entire piece would cost. It goes back to the firewall and wraps around the passenger side fender well.
