SolstitialFish Fuel Line Hose Kit 10ft (6 ID Sizes) NBR 300 PSI with 20 Clamps for Gas & Diesel

SolstitialFish Fuel Line Hose Kit provides six common inner-diameter fuel hoses totaling 10 feet, rated to 300 PSI and supplied with 20 clamps for secure gas and diesel connections.

This kit is designed to give mechanics, fabricators, and DIYers a ready set of fuel hoses and clamps for repairs, prototypes, or routine maintenance. The hoses are manufactured from NBR (nitrile butadiene rubber) for resistance to petroleum products and are offered in six sizes to match a wide range of fittings and engines. With the included clamps, you can assemble or replace fuel lines quickly without sourcing multiple individual components.

What sizes and quantities are included in the kit?

The kit contains six different inner-diameter hoses to cover common fuel line needs, plus twenty hose clamps so you can secure multiple connections. This range minimizes the chance you'll need an additional part when performing multi-point repairs.

• Hose sizes: 5/32", 3/16", 1/4", 5/16", 3/8", 1/2" ID
• Total hose length: 10 feet across all sizes combined
• Clamps: 20 metal worm-gear style clamps for adjustable, tight seals

How well does the NBR material handle gasoline and diesel?

NBR (nitrile) compounds are formulated for compatibility with hydrocarbon fuels, offering good resistance to gasoline, diesel, and many oils. While NBR resists fuel permeation and swelling better than some general-purpose rubbers, correct installation and routine inspection are still recommended to maintain performance.

• Designed for contact with petroleum-based fuels
• Durable against oil absorption and softening compared with standard rubbers
• Suitable for typical automotive and small-engine fuel systems within rated pressure

Is this kit suitable for pressure applications and how are connections secured?

The hoses are rated to 300 PSI, making them appropriate for many low- to mid-pressure fuel system tasks such as return lines, feed lines on small engines, and custom routing. Secure connections are achieved using the included worm-gear clamps, which allow fine adjustment for a tight, leak-resistant fit.

• Working pressure rating: 300 PSI (verify suitability for your specific system)
• Clamps are adjustable to fit each hose-fittings interface securely
• Proper clamp placement and hose length selection improve sealing and service life

How do I choose the right hose size and install the kit correctly?

Measure the barb or fitting outside diameter and match to the hose inner diameter for a snug slip fit; if in doubt, opt for the next larger clamp position to avoid pinch. Cut hose ends squarely, push fully onto the fitting, then tighten the clamp until the hose is compressed without cutting into the material.

• Match hose ID to fitting OD for a secure slip-on connection
• Use a straight, clean cut and avoid over-tightening clamps
• Inspect after initial run and re-torque clamps as needed

Who is this kit for? The SolstitialFish Fuel Line Hose Kit is aimed at home mechanics, small engine technicians, marine hobbyists, and anyone who needs a convenient assortment of fuel hoses and clamps for repair, maintenance, or custom projects. It’s particularly useful when you need multiple sizes on hand for troubleshooting or building prototypes. If you require hoses for high-temperature, high-pressure, or ethanol-blended fuel systems beyond typical automotive or small-engine use, consult system specifications and consider specialty hoses designed for those conditions.
