Continental marine fuel fill/exhaust hose 1.5" ID x 48" — USCG fire‑resistant nitrile construction

The Continental 58524 is a 1.5-inch inside-diameter, 48-inch marine hose engineered for fuel fill, tank venting and exhaust use with gasoline, methanol, ethanol and diesel.

Built for boat and small-craft fuel systems, this hose combines a fuel-resistant nitrile inner tube with a reinforced, wire-spiraled construction and a durable chemivic outer cover. It meets US Coast Guard fire-resistance and AE J1527 standards for marine fuel applications, and is rated to handle a broad operating temperature range for reliable seasonal performance.

What materials and construction make this hose suitable for fuel applications?

The hose uses a black chemigum (nitrile) inner tube that resists permeation and degradation from common fuels. That tube is covered by two synthetic plies plus a helix wire reinforcement to maintain shape and prevent collapse under vacuum or pressure. The external chemivic (nitrile/PVC) wrap protects against abrasion, oils, and UV exposure.

• Nitrile inner tube for fuel resistance
• Two synthetic plies for mechanical strength
• Helix wire to resist kinking and collapse
• Chemivic outer finish for weather and abrasion protection

Which fuels and marine roles is the Continental 58524 approved for?

This hose is intended for use with gasoline, methanol, ethanol and diesel in marine service, making it versatile for fueling, filler necks, tank vents and some exhaust connections. It complies with AE J1527 and USCG CFR33 183 Subpart J for Type A fire resistance, so it’s specified for many regulated fuel-fill and vent scenarios.

• Gasoline, methanol, ethanol and diesel compatible
• Suitable as a fuel filler neck or fuel tank vent hose
• Meets USCG fire-resistance and AE J1527 requirements

How does temperature and durability performance look for seasonal boating?

The hose operates from -25°F to +212°F (-30°C to 100°C), covering freezing winters and summer engine-room temperatures. The reinforced build and protective cover provide good resistance to abrasion, flexing and common marine contaminants so it holds up through routine use and storage cycles.

• Operating range: -25°F to +212°F (-30°C to 100°C)
• Reinforcement reduces risk of crushing or kinking
• Outer cover resists abrasion, oil and UV exposure

Are there installation or compatibility cautions to know before fitting?

Install using clamps and fittings rated for fuel systems and sized to the 1.5" inside diameter. Do not attach reducers to this hose unless those reducers meet equal fuel-resistance specifications to avoid weak points in the system. Follow USCG and local marine codes for routing and securing fuel hoses.

• Use clamps/fittings sized for 1.5" ID
• Avoid reducers unless they share the same fuel-resistant rating
• Route and secure per USCG and manufacturer recommendations

Who is this for? The Continental 58524 suits boat owners, marine technicians and shipyards needing a compact, approved hose for fuel fill lines, tank vents or certain exhaust duties on small craft. It’s a practical selection when you require a USCG-compliant, fuel-resistant hose with reliable reinforcement and a durable outer cover for seasonal or year-round use.
