Default Vaccum line at throttle body

1995 Bonneville SE

I needed to get the new elbow and tee that attach to the throttle body on my bonny. Right now the elbow is attached to the upper barb and the tee attached to the lower barb coming of the throttle body. When I went to the dealer to get these parts their diagram showed them in reverse order. I tried this but the way the elbow is made and with a longer leg than the tee and the upper barb sets farther back on the manifold so I don't see the dealers diagram being correct.

Does anyone have any thoughts on this and what is correct. I have pic'* if needed. (Can I post pics in the forum? I see a few on some of the threads.)

You can post pics here, I've seen them before. I have a 95 Bonny and had to rig together a complete vacuum system because all those little tees broke, so I'm not much help

On my '95 SE, the top fitting on the throttle body is an elbow that feeds vacuum to the vapor canister purge valve. The fitting underneath is a tee fitting that feeds the vacuum modulator on the trans and the fuel pressure regulator.

Pictures are included in threads here by the use of image links. You must upload your images to a web hosting site, like http://www.Photobucket.com then link them using this format: . This format is one of the quick links you can copy under your image in your free Photobucket account and paste into your reply here. Before you link them here, please make sure your images are no wider than 650 pixels. You can resize your image width in Photobucket or to save time, do it before you upload. A 650 pixel width will prevent the need for everyone to scroll right and left through the entire thread to accommodate an image that is too wide.

Please post pictures.

Everything Bill said above he is very smart.

This is a picture of my 96 Regal L36 motor.
The pictures that the GM parts people order from are wrong for my car also.
I think if you have them look at the pictures for a 96 Bonny SE it will show the vacuum lines for your 95.

I think a Bonny forum member gave me the correct part number for the lower vacuum pipe with the rubber T.
The part number for the lower vacuum line with the rubber T is # 24506302.

Guys, thanks for the responses. I have the parts and it sounds like my system is connected correctly it looks like the Regal pic and is connected like Bill'*.

Thanks again just wanted to double check that everything was correct as installed.
