Where to get new throttle body vacuum hoses...

[chullend]

Hello, and thanks for all the helpful articles. As this is my first post please believe its not my first time here. Heres a question I havent seen addressed here before. I just bought a new throttle body for my 4.9l 92 Eldorado (didnt really need the throttle body but it came with the ISC and TPS, which I needed, and for about the same price those would have cost) but I cant find the little formed vacuum hoses that connect to it. Some are 90 degrees and some are just straight. I am almost certain that when I disconnect the old ones they are going to crack and/or disintegrate. Cant find them at the auto parts stores, GM website, or anywhere else for that matter. Only other option would be a salvage yard but theyre not likely to be in any better condition than what I have. Any help locating new ones or suggestions for saving my old ones would be greatly appreciated.

A similar post was made a couple of weeks ago. Probably a different model year, but I think the answer is still the same.....dealership. In addition, the other post indicated that they weren't cheap, but what else would you expect.

Ditto, that was me that said they were not cheap.

Despite these parts may be not expensive at dealership, you can buy a few feet of a vacuum hose of appropriate diameter from Adavance or whatever parts store. Thats what I did to replace the plastic vacuum lines with cracked elbows.

I would think, please keep in mind I am no expert, that if you used regular vacuum hose and tried to put it at a 90 degree angle it might kink and restrict air flow. Although, that is an inexpensive option that I may resort to if the dealership price is just outrageous.

It is up to you, but there is plenty of room for the vacuum hoses, so no kinking at all.

Use the appropriate OD copper pipe at the bends.

Fill the copper pipe with sand before you form the bends to prevent the copper from collapsing.

Whatever works.

You could use brake line for the bends. ADAP and others sell hand-held mandrels for bending bulk brake line that can be used to make small sections of vacuum line.

I recently had to repair a section of windshield washer fluid line on a 1999 Silverado truck. The lines were the molded plastic, very similar (if not identical) to the vacuum lines on most engines. These lines turned out to be very near 1/4" O.D. So using some 1/4" I.D. rubber hose from the car parts store worked perfectly. Just slip the new rubber hoses over the remenants of the old plastic ones and you have a permanent repair....no leaks. Buy small spring clamps if they don't fit tightly.
