Can't find the OEM one anywhere. Seems they discontinued it years ago. Some people recommend a Dorman one but what I've read is the hose fitting on it is too small for the OEM line. I also want a new gasket that plugs into the brake booster side as after 160K I think it's cracking.

Anyone have any idea on either where to get the OEM one or an OEM replacement? The GM part number is 92148960 and by what I've found, the 04's have a different one that won't fit the 05/06's.

I thought about actually ordering it from them a few days ago but after 3 dealerships cancelled my order along with Jegs I expected them to do the same. I was trying to find a new one and didn't want to go the used route..yet.

Bumping an old thread to help people out in the future.

NAPA carries one that's ALMOST an exact replacement.

Part number 89000 in case they change the link the future.

The 5/8ths side is a perfect fit into the brake booster and the hose side is almost a perfect fit for the vacuum line going to the engine. About 6 wraps of electrical tape around the hose end nipple and it makes it a perfect fit.
