🌟 🌟 🌟 🌟 🌟 5 star review from 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.

PTFE Hose Specs that actually matter for LS swaps
• Construction: PTFE core → stainless braid (all versions) → optional nylon jacket for abrasion resistance
• Temp range: −76°F to +392°F (stable pressure/flow hot or cold)
• Permeation: PTFE liner is ethanol-safe and E85-ready with virtually zero fuel smell

Size/Ratings (ID · OD · Working · Burst · Min Bend)
• AN6 — 0.320” · 0.478” · 2500 PSI · 10,000 PSI · 2.5”
• AN8 — 0.420” · 0.550” · 2000 PSI · 8,000 PSI · 3.5”
• AN10 — 0.500” · 0.650” · 1500 PSI · 5,000 PSI · 4.5”

LS swap notes
• GM LS rails target ~58 PSI—our working ratings give massive headroom for EFI stability.
• Typical feeds: AN6 for stock→mild builds and most return-less setups; AN8 when fuel demand rises (boost/long runs); AN10 for high-flow return-style or dual-pump systems.
• Pair with a Corvette-style filter/regulator for clean 58 PSI control; our version uses built-in AN-6 male fittings for simple plumbing.
• Use the bend radius numbers above to route around frames/crossmembers without choking flow.

Lifetime warranty. Built to handle real fuel system pressure, not just look pretty.

AN vs. ORB vs. NPT vs. NPSM — stop guessing, stop leaks.

• AN (37° flare): No tape.
• ORB: O-ring seals the boss. No tape.
• NPT (tapered): Use thread sealant.
• NPSM (straight): Washer seal. No tape.

We break down where each fitting belongs, how they seal, and the gotchas that cause most fuel/EFI headaches. Read the full guide — link in bio .
