1/8th matches the original 3.2mm spec basically exactly (whereas most silicon hoses are 3, 3.5, 4mm). It’s also fuel, oil, and UV resistant so can be used for the PCV to throttle hose (carries oil residue). It’s also a pretty damn cool yellow lol 😎 (stock black and yellow engine bay?).
Ordering it from US Plastic also allows me to snag high quality kynar/viton valves for next to nothing.
