I need to get a reading on the Tb seat and Maf your note about a hose reducer might work. It has about 1/2 inch or so to grab on the bottom off the TB. A clamp is now on there and would hold a hose in place. Welding a tab would be plan B or C or you know. Too me this is a weak link at best.

Tim,
It' not that it will pull out, it's together tight but as it sits in the intake it moves around just a tad. This will cause the top rubber ring to move enough to create an air leak. This was an issue with the old air box getting it just right as to not **** it sideways. I do not think this can be placed to be rock steady this is my big concern on this whole project "besides the chip". I'm almost done the install but do not want to leave this way and have to take everything apart again. Any word on the restrictor ?

I see you have an o-ring on the MAF and I do not think it belongs there. There is an o-ring inside the cast aluminum where the MAF slips in and that is all that is needed to seal that area up. Take off the o-ring wrapped around the MAF and I believe you will get a firmer fit.

Tampa,
I responded to the other thread you revived from Imre (Imo000) but here's the setup he uses, I'm pretty sure it's just a hose clamp and the two pieces of fabricated metal on the sides.

For the o-rings, I'm pretty sure there's one thin one that goes around the base of that shoulder on bottom of the MAF and then there's a thick one that fits into a recess in the throttle body. I recently replaced both on mine.

Down where the MAF fits int the intake - there is an o-ring inside a grove. Same exact setup on the 80-84 US L-Jet cars (just a smaller opening). Seals up just fine under 17psi on my car.
I do not have PET at the moment to look into this, but it seams unnecessary. The one large o-ring down in the recess is more then enough to seal the MAF.

I had a closer look at the picture (very nice by the way) and just want to clarify the way the MAF is secured.
The two T bolt clams hold the tie strap, and the tie strap holds the MAF in place, right? The tie strap at the bottom is sitting over the casting of the J pipe, right? The bottom clamp is also sitting on the J pipe but before the end of the tie strap? Looks like a much simpler setup of what I built. Its nice to see a different variation of the same thing.
