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!

That is 90' only....91' vapor canister vacuum goes back under plenum.
90' Plenum........................................ ................................91' Plenum with TB Coolant Blocked
please post a photo of what you need Im not quite sure how all the lines run again im kinda rusty but I have lots of parts I might have one.
If its the one that plugs into the plenum, That one has been hard to come by not sure if I have it or not.
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.
Phrogs, here is a little sketch of what it looks like. One hole connects to the aluminum PCV line that runs to the back of the plenum on the driver's side of the '90 ZR-1. The other hole connects to a black plastic line that runs to the charcoal canister under the drivers side head light.
I could use one of those 1990 Plenum dual hose adapters also if it is original.....replacing a makeshift hose arrangement I made up to get by
