How's it going y'all. I've got an 04 Monte SS Supercharged that has a vacuum leak. Has anyone had any experience using this vacuum line kit from HPSI?. The T fittings on mine cracked once again. I'm hoping the fittings on their kit are made of better material compared to the dorman brand ones. I was even looking into the zzperformance vacuum kit as well. Any advice is greatly appreciated. Thank you

 

Never heard of this place, but to me it looks no differnet than the dozens of places out there that offer generic Chinese silicone tubing in all kinds of sizes. I wouldn't expect it to be anything special.

Dorman and a few other places make brass Ts for like $5 if you keep breaking them for some reason. I strongly suspect that's what ZZP uses for their "kit" at a grossly inflated price.
