Need 90-91 PCV/vapor canister to plenum connector
Hi guys, I'm in search of the rubber connector that connects the PCV pipe and vapor canister line to the plenum on the 90-91's. It's the little double barreled rubber connector that sits right under the throttle position sensor on the left side of the throttle body. If anyone has a spare, or a source for one, I would greatly appreciate it. Will gladly pay for part/shipping, thanks!

Re: Need 90-91 PCV/vapor canister to plenum connector
Check with Mr. Marc Haibeck at Haibeck Automotive Technology. I bought one from him a few months ago. Another option is to cut two pieces of fuel hose the length you need to slide on the nipples and the lines slide in the other end of the fuel hose. Forgot the exact size fuel hose, but I'm thinking 3/16 inch.

Thanks agpilot. I've been using hose for a long time, but I'd like to have the proper connector. I'll contact Mark and keep my fingers crossed that he has another spare.

The Rubber Tubing Adapter in question is a block of rubber about 2 inches long and 1.5 inches wide by 3/4 inch high with two holes side by side all the way through the 2 inch length. The block of rubber slides onto the two Plenum Ports shown. On the other end of that Rubber Tubing Adapter the charcoal canister vacuum line is plugged into the left port and the PCV vacuum is plugged into the right port (the hard PCV tube attached along the drivers side of Plenum coming from the PCV Dual Connector at rear of Plenum). The other solution is to separate the two male nipples shown just a tad (by bending) and use two separate rubber hose connectors (the rubber hose being approximately 3/16 inch ID and each hose being approximately two inches long). I could use one also. The Rubber Tubing Adapter discussed here is only a 1990 LT5 item. 1990 Plenum with Throttle Body Coolant Nipple shown. As an aside...... The Top (smaller) male nipple shown on this 1990 photo (above photo) is the Throttle Body (TB) Coolant Nipple (Coolant Input Port). On this 1991 Plenum (below photo) I have BLOCKED the TB Coolant Input Port. Normally on all 1990s and 1991s I only block TB Coolant at the Injector Housing and leave the TB male nipple in place on the Plenum shown in the 1990 Plenum (above photo) with the TB Coolant Hoses in Place so it appears TB Coolant is NOT blocked when in fact it is. You have to also then block the TB Coolant rubber hose returning to the Coolant Reservoir on the Passenger Side of the Plenum. 1991 Plenum with Throttle Body Ports plugged with red 1/8 inch pipe plug. See 1990 and 1991 Plenums and TB Coolant Blocking at IH

Here's a little sketch of what it looks like. It's a simple block of black rubber about 1.5 inches long.

Re: Need 90-91 PCV/vapor canister to plenum connector
Sometimes when I run into a hard to find vacuum part like that I go to the junkyard and start looking at other cars with similar parts that might be adaptable. Being GM, probably half a chance some cadillace or whatever used something similar.
