ordered 2' of 1" ID silicone pipe, 8' of vac line, and two worm clamps. Also gave up on finding barbed fittings for my vibrant block, I have been to home depot, loews, autozone, pep boys, advance auto, napa, local hardware store and no luck finding a fitting that screws in. I have been looking for the 1/8" NPT thread fittings but it only goes in for two threads then stops, 3/16" is too big too and I cant find anything smaller. so im just gonna buy a brass T fitting for the brake booster until i finally find the barbed fitting for my vac block. oh well
