If you look at the side of a fuel hose, you will see the letters "SAE" followed by the number 30 (some will have a J first). Next in the sequence will be the letter "R" followed by a number. The number after the "R" refers to the section of the performance standard it pertains to. The criteria are typically permeation, chemical resistance, construction, temperature range and kink resistance. The higher the standards go, the more criteria that must be met.
"R" numbers in some cases do not determine the pressure rating for the hose. Hose manufacturers typically print on the hose if it is intended for use on fuel injection systems. Also, you should check with the manufacturer of the hose to see if it is compatible with fuels like E85 or biodiesel.

SAE 30R6 hoses are designed for low-pressure applications like carburetors, filler necks and connections between tanks. In most markets, SAE 30R6 has been replaced by SAE 30R7
SAE 30R7 hoses are designed for fuel. These can go under the hood and are typically used for low-pressure applications like carburetors or a fuel return line. It can also be used for PCV connections and emissions devices.
SAE 30R9 hoses are designed for high-pressure applications like fuel injection systems. Often SAE J30R9 is also CARB approved meaning it is EPA certified to a low permeation standard. This means the hose is designed to contain fuel evaporation through the cover.
SAE 30R10 includes hoses that are submerged in fuel. This type of hose is used inside the fuel tank and typically on the fuel pump module. This type of hose uses a special layer on the inside and outside to prevent the core layers from being saturated in fuel. But, don't use it under the hood. R10 hoses can't stand the heat.

Disc Brake Hydraulic Hose
Brake hydraulic hoses are the flexible hoses that connect the hard lines that run along the body or frame of your vehicle to the brake calipers. Brake hoses are unbique in the fact they are designed and sized properly to move with the suspension as it travels up and down over bumps in the road.
Since brake hoses carry hydraulic fluid as well as transfer pressure to the brake calipers/wheel cylinders it is critical to inspect these hoses regularly for any types of fraying or external cracks. Traditional rubber hoses tend to shrink over time internally restricting the flow of pressure to the brake calipers. Because of this FCP Euro recommends replacing brake hoses in matches pairs to ensure even braking performance at each corner of the axle.

To further improve the factory braking capabilities of the automotive, we created our Unplugged Performance Stainless Steel Sport Brake Line Set. For those who demand higher performance and better brake feel from their automotive, these brake lines are a must! By upgrading to the Stainless Steel Sport Brake Line Set, you'll notice a much firmer, much more responsive brake feel. The more-responsive, more-accurate feel will allow for more sensitive braking adjustments.
Brake line connects hydraulic brake actuator to trailer brakes when used with additional lines, tees, and fittings (sold separately)
Flexible design makes hose perfect for use with foldaway trailer tongues, disc brakes, and torsion axles
Stainless steel flares resist corrosion and are stronger than brass to reduce splitting
Ideal for boat trailers
Deep threads improve connection to help prevent leaks
Rubber hose meets DOT and SAE standards
Fittings on both ends are durable and rust resistant
90-Degree male swivel flare nut is great for applications with limited clearance
Bend in fitting keeps you from having to bend hose
Swivel allows flare fitting to turn without the hose twisting
Female inverted flare (FIF) fitting easily threads onto a male fitting
Double-crimped ferrules securely clamp fittings to hose
Open area on fittings lets you use a line wrench for a better grip
Minimizes the risk of stripping threads
