Pretty sure I have a boost leak, I'm gonna take apart the front bumper and change out the original worm clamps, I couldn't get the t-bolt clamps on originally when I installed my fmic last year.

I tied to use a 67-72mm which I thought was 2.5" (maybe they were more like 2.25") but it was too tight, so I gave up and re-used the stock clamps... my mistake!

What size t-bolt clamps should I use? 2.5" or 2.75"?

HPS (SSTC-76-84) 76mm - 84mm Stainless Steel T-Bolt Clamp for 2-3/4" Hose https://www.amazon.com/dp/B0058W7X0A/ref=cm_sw_r_cp_api_UYkvybQD3H90C

2.75. The inlet/outlet pipes are 2.5, after the hose is on you'll need a little more room. The 2.75 will tighten down just fine.

HPS Stainless Steel T-Bolt Clamp 70 millimeter-78 millimeter (2.76 inch-3.07 inch) for hose with 2-1/2 inch (63 millimeter) inside diameter. I was basing it off of the outer diameter after researching the ID requirement..

Works well.

Looks like I'm just gonna buy both sizes from Pepboys and return whichever one doesn't work!
