CAC Air Pipe Connector
I was checking for potential leaks in my charged air cooler system and discovered that this connector is close to failing. It's the one that connects the CAC to the air pipe (then to engine intake). One of the  automotive A/C hoses has been...

You can put  a length of duct tape around the holes to get you by till new ones found. Use a clamp to hold tape over holes, does not need to be tightened too much


 Pressure is only up to 35lbs.

Thanks for the replies. I'm going to try and find the exact flexfab replacement. I'm at home so no emergent condition. FFR, the CAC end is 4" bu the end I need is actually the intake end which is 3.5". I'll check those tabs; thanks for the tip.

John, when I had my CAC off years ago to repair holes in it I tested mine to 45 lbs over night and it was solid. I used 2 pieces of 3/4"plywood with a hole in centre of each one, I put a gauge at one end and air fitting on other then pumped air...

I ended up getting the hose from the place David recommended - Intake Hoses. It was about $35 versus $80 and up elsewhere. It turns out this size (3.5") is not common. All the hose from the turbo and through the CAC is 4" but the air pipe is...
