POHIR 3/8" Marine Fuel Line Hose 10 ft — 300 PSI, SAE J1527 Type A1-15 V-0 flame retardant

POHIR 3/8" Marine Fuel Line Hose is a 10-foot, SAE J1527 Type A1-15 rated feed line built for boat fuel systems, offering 300 PSI working pressure, V-0 flame-retardant outer construction, and compatibility with gasoline, diesel and E85.

Designed for marine and recreational power applications, this fuel hose combines reinforced construction, low permeation performance and a wide temperature range to meet the demands of on-board fuel delivery. Its 3/8" inner diameter and 5/8" outer diameter provide a common fit for small engines, fuel pumps, filters and tanks on pleasure craft. The hose is engineered to resist UV, weathering and common fuels while delivering consistent flow and safe containment under typical operating conditions.

How strong and temperature-resistant is this fuel hose?

The POHIR marine fuel line is engineered for reliability under stress: a maximum working pressure of 300 PSI with a bursting pressure around 900 PSI, and a usable temperature window from -22°F to 212°F. These parameters ensure it maintains integrity across cold starts and warm running conditions found in marine environments.

• Working pressure: 300 PSI
• Burst pressure: ~900 PSI
• Temperature range: -22°F to 212°F
• Inner/outer size: ID 3/8" / OD 5/8"

What materials and safety features does the hose include?

This fuel line uses a three-layer build: an NBR (nitrile butadiene rubber) inner tube for fuel resistance, a polyester fiber braid reinforcement for pressure handling, and an NBR+PVC outer cover formulated to meet V-0 flame-retardant performance. The outer compound also improves abrasion and UV resistance for long-term marine exposure.

• Inner: fuel-resistant NBR for low permeation
• Reinforcement: polyester fiber braid for strength
• Outer: NBR+PVC rated V-0 flame retardant
• Weather and UV resistant outer cover

Which fuels and applications is this line suited for?

The hose supports common marine fuels including gasoline, diesel and ethanol-blended fuels like E85, making it versatile for outboard engines, inboard systems, generators and auxiliary equipment. It meets SAE J1527 Type A1-15 standards which are specified for pleasure craft fuel lines with very low permeation performance.

• Compatible with gasoline, diesel, E85 and similar fuels
• Fits fuel pumps, filters, tanks, engines, and small generators
• Designed to meet SAE J1527 Type A1-15 requirements
• Low fuel vapor permeation for environmental and safety benefits

How do I install and maintain the POHIR marine fuel hose?

Installation follows common marine fuel-line practices: cut squarely, secure with approved clamps or fittings, and avoid sharp bends or kinks. Regular inspection for chafing, cracks or hardening and replacement every few years or per regulatory guidance will help maintain safe operation.

• Cut clean and use compatible fuel fittings and clamps
• Avoid pinching, tight radii and rubbing against hardware
• Inspect periodically for wear, leaks and hardening
• Replace if damaged or after service-life recommendations
