Fuel Your Build with the Best – AN PTFE Hose, LS Swap Kits & EFI Fuel System Solutions

At Hot Rod AN LLC, we specialize in helping builders of all skill levels create reliable, clean, and professional-grade fuel systems using high-quality AN PTFE hose, fittings, and fuel system kits. Whether you're working on an LS swap, upgrading from carbureted to EFI, or building a custom vehicle from scratch, our product lineup is built around one goal—getting you the right parts the first time.

We’ve taken the guesswork out of performance plumbing. From complete LS engine fuel system kits to PTFE AN hose fittings and AN hose bundles, every item we carry is tried, tested, and proven to hold up under pressure—even in high-performance and ethanol-blended fuel environments.

What sets us apart? It’s more than just quality parts. We design our kits and bundles with the builder in mind. That means fittings that seal, hoses that don’t stink up your garage, and complete solutions that save you time and frustration. We know what works in the real world because we build these systems ourselves, not just stock them on a shelf.

Built for LS Swaps, EFI Conversions & Modern Fuel Systems

Doing an LS swap on your squarebody C10, K10, or Blazer? Upgrading your classic to EFI? We offer purpose-built solutions to make those installs clean, reliable, and long-lasting. Our fuel system swap kits are built around PTFE hose to eliminate vapor smell and fuel permeation issues common with traditional rubber-based AN hoses.

We also carry components like inline and in-tank fuel pumps, high-performance fuel filters, and EFI sending units so you can complete your entire fuel system in one order. No more piecing it together from five different stores. Everything here is curated to work together—and work well.

Why PTFE Hose?

PTFE-lined AN hose is the future of fuel system plumbing. It resists modern fuels like ethanol and E85, doesn’t break down over time, and virtually eliminates fuel vapor smell. If you’re tired of cracking rubber hoses or the gas odor in your garage, upgrading to PTFE is a must. Our hose kits include everything you need to plumb your project safely and cleanly, including your choice of color, length, and fitting angles.

You don’t have to be a fabricator or shop owner to build a clean fuel system.
