I have recently bought a LS3 intake setup that came with a FAST 90 TB. My question is where do I get the tube that goes into the top passenger side of the throttle body. A Hose connects from that and goes into the passenger valve cover. I hear it tells you in the instructions but I don't have those. Any help would be greatly appreciated and I did try to search.

 

Anybody know... Out of all the people that are running a FAST TB nobody knows...

 

I don't have a FAST TB but failing all else, I'd go
looking for a 1/8" pipe - 5/16 barb fitting (like
come with cheapo pancake fuel pressure regulators,
those are nice and short), overdrill & tap the hole
and there you go.

Not sure whether the hole is the same size as stock
TBs. If so, take your stocker, put a #2 philips up the
fitting as far as it'll go, work it loose, swap it over.
