AN PTFE Reusable 90 degree swivel hose end - AN6, AN8, AN10
Anthony Vogel

Great quality. I ordered some other brand from Amazon and put it side by side with Hot Rod AN lines. The HoT Rod AN fittings have a much thicker side wall and feel more solid. Great product at a great price.

Top Notch Service

Ordered a fuel tank and FedEx lost it. After a frustrating call with FedEx customer service, I emailed Hot Rod Fuel Hose and they were ON IT! They took FedEx to task and I suddenly got shipping updates. Great products and even better service.

I am doing a 5.9 efi swap into a 65 dodge sweptline. I called and told them what I wanted to do with fuel lines. they asked a few questions and told me what I needed, so I ordered. shipping was fast and to my surprise it was exactly what I needed to complete the fuel lines. kudos to our freinds north of the border. wouldn't hesitate to use you again.

How Hot Rod AN LLC started

The Origin of Hot Rod AN LLC – Built from Experience, Driven by Passion

Our journey began with a rough but promising Chevy C10 project truck. Like many builds, it demanded more time and money than expected—but it also sparked an idea. During the EFI conversion, we realized how overpriced and limited the options were for high-quality AN PTFE braided hose and AN fittings for performance fuel systems.

That frustration led to the original launch of Hot Rod Fuel Hose. We sourced manufacturers, ordered samples, and rigorously tested products to ensure reliability, safety, and compatibility with modern automotive fluids. The goal? Offer high-performance AN hose and fittings at a price that makes sense for everyday builders, racers, and enthusiasts.

After Hot Rod Fuel Hose ceased operations, the mission didn't end—it evolved. Hot Rod AN LLC was born to carry the torch and deliver even better service, product selection, and support for the DIY and professional automotive community across the USA and Canada.

We’re proud to serve customers who are building EFI systems, fuel delivery setups, and complete AN plumbing solutions with confidence. Whether you're working on a classic truck, performance car, or race vehicle, Hot Rod AN LLC is your trusted source for PTFE braided hose, AN fittings, fuel system kits, and more.

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.

The Hot Rod AN Difference

You don’t have to be a fabricator or shop owner to build a clean fuel system. We cater to both weekend wrenchers and professional installers with easy-to-use products, detailed install guides, and custom system planning. Need help figuring out what fittings or hoses you need?
