AC PERFORMANCE 3/4" NBR Push-On Fuel Hose 2ft Black — E85‑Resistant, -12 AN Compatible

AC PERFORMANCE ID 3/4" NBR push-on fuel hose is a 2‑foot, non-conductive nitrile rubber line designed for push‑on AN fittings and compatible with gasoline blends such as E85 and E10.

This push‑on hose combines a high‑grade NBR (nitrile rubber) inner liner with textile reinforcement and an elastomer cover to deliver a resilient, flexible fuel line for automotive and marine applications. Built to mate with 400 and 510 series push‑on hose ends, the hose handles common fuels, oils, and coolants across a broad temperature range and carries a working pressure rating suitable for many fuel‑system installations.

How does this hose perform with ethanol blends like E85?

The nitrile rubber formulation resists swelling and degradation from ethanol‑containing fuels better than many generic rubbers, making it suitable for E85 and E10 use. While compatible with common fuel blends, routine inspection and correct installation are recommended to maintain reliability.

• Material: high‑grade NBR inner liner for ethanol resistance
• Suitable for E85, E10, gasoline, oils and lubricants
• Recommended: clean hose thoroughly before first use

Will this hose fit my push‑on AN fittings and what sizes are supported?

This hose is sized for -12 AN (3/4" inner diameter) and is specifically compatible with 400 and 510 series push‑on hose ends. The outside diameter and wall construction are designed to accept those push‑on fittings without additional adapters in most standard installations.

• ID: 3/4" (19.1 mm) — matches -12 AN sizing
• OD: 1‑1/32" (26.2 mm) for common push‑on grips
• Works directly with 400 & 510 series push‑on hose ends

What are the temperature and pressure limits for safe operation?

The hose operates across a wide range, from cold starts to elevated engine bay temperatures, but should be clamped when temperatures exceed 70°C for added security. It carries a working pressure rating suitable for many fuel system applications and a high burst pressure for safety margins.

• Operating temperature: -40°C to 100°C
• Working pressure: 280 PSI
• Burst pressure: 800 PSI
• Use clamps above 70°C for best results

How should I prepare and install this hose for reliable service?

Proper preparation ensures sealing and longevity: always flush and dry new hose before installing to remove manufacturing residues, and verify push‑on fittings seat fully. Use clamps when systems run hot or where fittings may experience axial loads; inspect connections regularly for wear or leaks.

• Thoroughly clean hose interior before first use
• Push fittings fully into the hose until seated
• Use a clamp when ambient or fluid temperature exceeds 70°C
• Inspect periodically for softening, chafing, or leaks

Who is this for: AC PERFORMANCE's 3/4" NBR push‑on hose is aimed at automotive and light‑marine enthusiasts, racers, tuners, and professional mechanics who need an ethanol‑compatible, flexible fuel line that pairs with popular 400 and 510 series push‑on AN hose ends. It’s a practical choice for fuel, oil, and coolant routing where flexibility, chemical resistance, and straightforward push‑on assembly are priorities. If you require higher temperature capability or conductive lines for grounding, consider hoses designed for those specific needs.
