Brake booster vacuum hose question

[Nodnarb76]

In the middle of swapping a 2004 LQ4 into my 87 Suburban, I have realized the nipple on the back of the intake manifold is a different diameter than the nipple comming off my brake booster.
Assuming I'm not the first person to run into this, was wondering what the solution is?

Take a look at GM Part # 12559760. Its the adapter I used on the swap in my 72.

That looks like the same nipple I have on my manifold already. The brake booster hose is too small to fit over the end. Fists on the smaller nipple on the booster just fine.
Appreciate the help though🙂

OEM LS booster vacuum hose worked perfectly for me. That might be an option.

I went to orilyes and bought a 90* rubber elbow in the help section then used an crossover adapter barb. Made for a clean install

Yea not sure if it was a pvc elbow or what. Kinda looks like a spark plug boot. It's in bubble wrap. You should find it easy. Just look around....
