Why Hot Rod AN Exists
Hot Rod AN LLC was created in 2025 to carry forward the mission that started at Hot Rod Fuel Hose: make high-quality PTFE-lined AN plumbing accessible and affordable for real-world builds across North America.
Our focus is AN PTFE hose, PTFE hose ends, adapters, filters/regulators, pumps, and swap-ready kits—backed by plain-English guides in our AN Hose 101 library.
From a stubborn C10 to a better way to plumb
It began with an EFI upgrade on a well-used C10 Squarebody (FiTech). Rubber-lined hose struggled with modern fuels. We tested relentlessly and committed to PTFE for performance, longevity, and clean garages—no fuel smell.
If you’re building a Squarebody, grab our deep-dive: Ultimate fuel system guide for 73–87 C10/K10 Squarebody.
What sets Hot Rod AN apart
PTFE-only where it counts
PTFE liners resist ethanol-blended fuels, reduce vapor permeation (no stink), and handle EFI pressures and under-hood heat when installed correctly.
Learn: PTFE vs. rubber-lined hose
Engineered kits & real fitment
Return & return-less LS layouts, hose bundles sized for common builds, and adapters that just fit—so you spend more time driving than troubleshooting.
