Trying to figure out what to order. I don't know what the parts are called. There are two hard plastic vacuum tubes on the front of the 3.8 engine. One is about 4" with a couple 90 degree bends to a diaphragm. The other is about 8" long with a 180 degree bend into a small cylindrical thing. They got broke when someone changed my thermostat.
Any help greatly appreciated....

 

I got it figured out....

 

Just a heads up, to replace that, I am not sure any of the parts stores can get that assembly. You *might* be stuck going to a GM dealer (that is what I had to do when mine broke).

 

I found one on ebay not too long ago

 

Yes, a couple ebay sellers have this assembly for sale..

 

I found several on e-bay for sale and got one ordered. My biggest problem was trying to figure out what I had to buy. I'm not up to speed on these newer engines. When I worked on them, you only needed three wires to make them run, not a computer...lol We test fired some hanging on a chain hoist before putting them in a car.

 

I believe those parts are actually even being discontinued by GM. I remember when I needed to replace one on my old 98 Camaro with the 3800, I couldn't buy one new. Had to just go to the autoparts store and use standard vacuum tubing.

 

I gave some thought to threading a wire through the tubing to get the ends aligned and using heat shrink tubing to connect them. I think that would work.
I saw pic where vacuum tubing was used to replace the hard plastic and it looked pretty decent.
