Noticed after seeing a lean condition that this port on the back of my L92 truck intake is "broken" where it connects to the brake booster. After a bit of digging, there doesn't seem to be a replacement for this part available (only the part that goes into the push lock), which is weird because there is an o-ring on this part... Any advise on how to fix this short of gluing it in? Or, am I now in the market for a new intake?
Tap the hole with a pipe tap and screw in a hose barb.
This is a great time to take that intake and throw it in the garbage and get a LSXRT intake for it. Just saying, the power difference is huge. If you are on a budget, just follow what WTD said.

Thanks Dave.
My hesitation on changing out the intake is because I don’t really want to give up the low end torque. I’m not chasing dyno numbers, and all the data I’ve seen suggests that the truck intake is one of the best choices for torque. I’d be happy to spend the $ for something that would be an improvement, but spending $ on something that would make my car feel more sluggish isn’t what I’m after.
Is my logic flawed here?

Really? The power difference is huge? You obviously haven’t seen the data. Fast intakes are over rated, expensive and heavy. The factory L92 intake outperforms the LSXRT.
Ok, so, I'll work on getting this one fixed!
Thanks!
Nothing to fix. Again, the barb that’s broken is a removable piece. You slide the red collar toward the intake, and the barb pops out. It’s a quick release mechanism. You could pull the piece at a junkyard in like 2 minutes. Easy peasy. I might have one here. I’ll check tonight. If so, I’ll PM you and send it to you for free.

Thanks man. Yea, let me know. Take a look at my pics again. The removable piece that fits into the red push lock connector isn’t my issue. It’s the housing that the red push lock connector lives in that appears to be broken and now just wobbles inside the intake. It’s this housing, that I haven’t been able to find a replacement, and mine is the only one I’ve ever seen detach from the intake.

JB QUIK works great on many repairs so i would JB QUIK it to piece back.

Thatks false, completely. The Fast LSXRT will make substantially more power than an L92 or a ported stock LS3 car intake. The L92 will always have a choke point on #8 cylinder just from the design. Dont be an internet jockey, I actually build motors.
Thanks Dave.

Dont be afraid of losing torque w/ the LSXRT. It's a long runner similar to the L92, not a car intake. If anything, you'll gain some everywhere. The square port heads want big long runners to help the air speed w/o choking. The regular Fast LSXR car intake would lose some low end, that T at the end makes a difference.i have had in hand several ported L92 intakes and have seen pics of radically home ported ones and it's not worth it. The Fast just makes more power w/ better design and is port-able for even bigger power.
Thanks guys. A short while ago, I watched a video where they tested and reported the numbers on 18+ intakes and remember thinking how well the LS3 and L92 intakes did against the aftermarket. Now, I'm sure there are better aftermarket intakes available now days (LSXRT potentially) but this video supports my view that the $1k+ cost of an intake may not be the best bang for the buck. Here's the vid if anyone is interested.
Richard Holdener (I'd say, pretty qualified) has been the one to aggregate a lot of the data I've consumed on this subject, though, to your point, I've haven't built a lot of motors myself.
Here's another one where that point is again made:
I'm open to anything, but again, I'm not a drag racer, and power above 6k rpm isn't what I'm after (I'm after good throttle response and great street manners for my heavy car, thus, I like to see a nice flat torque curve under 6k) I'm yet to be convinced that the cost benefit is there for a fast over my stock setup.
If you have the L92 intake AND it can be fixed, use it! As you've seen, it works well. Would a FAST do more? Yeah. BUT at what cost? And the gains are MOSTLY up the scale. Would your butt-dyno feel it? Maybe, or not. As you sit, you WILL have a good torque curve.
