2004 4.0 liter!

Does anyone know where I can find a supply of elbows for the three (3) vacuum lines that attach to the side of the intake manifold? See the attached image.

Good question... I put tiny hose clamps around mine to snug em up last year.

Would these work

Silicone stays pliable even with turbocharger level under hood heat and lots is size and color choice

The problem is that the elbows fit over a 3/8" diameter nipple on the intake manifold, but connect to a .325" outside diameter vacuum line/hose on the other end. They are basically reducing elbows and I was unable to find a direct replacement. One of mine was rotting away; I eventually purchased the entire vacuum line from mopar for about $45.

Wrong Sizes!

I it looks like I may have to jury rig something up! I've been told by Mopar they have discontinued those lines!

The silicon ones do not offer the sizes needed!

Use some 2" sections of 5/16 hose

Silicone is more stretchy so can often use a little smaller then fitting size

Let us know what you come up with, I'd like to replace mine with something.

Someone on this forum said there's a Gm cross reference for those elbows sucks have them on my 4.0 tj

Here is what I have found for those elbows:

Front 1/4 port to 5/16 tube (to evap canister in rear) GM # 10124635 ($9.67) Dorman # 47038 ($5.99)
Mid 3/8 port to 5/16 tube (to purge valve) GM # 10124635 ($9.67) Dorman # 47038 ($5.99)
Rear 3/16 port to 5/32 (to cruise & A/C-heater) Dorman 766330 ($2.99 + frt)
Purge valve 5/16 tube to 5/16 port GM # 10124635 ($9.67) Dorman # 47038 ($5.99)
Edited, as spreadsheet lost formatting when pasted.

The front elbow requires a 5/16-3/8 hose clamp to secure.

A 5/16-3/8 hose clamp is also used on the middle to reduce the chance of cracking from expanding 5/16 over 3/8 (easy fit).

The GM part number came from this forum. I used one (on the front), then purchased Dorman from O'Reilly for the others.
