Fuel Lines

Fuel Lines: the plumbing that keeps fuel moving under pressure

Fuel lines carry gasoline or diesel from the tank to the rail and injectors, and on return-style systems back again. That job sounds simple until you remember it happens under constant pressure, with fuel that eats cheap rubber and heat cycles that harden it. A cracked, weeping or swollen line is a fire risk and a lean-condition risk, which is why people replace tired factory hose or step up to fuel lines that can handle more flow when they add a bigger pump or more boost. Braided line resists abrasion and heat, holds up to pressure, and lets you run proper AN fittings instead of hose clamps.

What we stock

This category shows 100 products with current prices from $31 to $1,000 - that range is what is in stock now, not a fixed offer. Across the sample there are 15 brands. Vibrant is by far the deepest with 49 products, followed by Radium Engineering (11), Gates (8), Russell (6), and smaller counts from Fleece Performance, Fragola, Snow Performance, Goodridge, Torque Solution, Injector Dynamics, COBB and others.

The mix runs from bulk hose to finished vehicle kits. Examples include the Vibrant -10 AN black nylon braided flex hose in a 150ft roll and the -8 AN version for building your own runs, plus complete kits like the Snow Performance 8AN braided stainless kit, the 10AN version, the COBB Subaru STI fuel rail line kit, and the Fleece Performance Duramax high-pressure injection line kit.

How to choose

The first split is bulk hose versus a vehicle-specific kit. Bulk rolls and AN hose give you flexibility to route and cut exactly what you need, but you buy fittings separately and do the assembly. Vehicle kits like the COBB STI and Fleece Duramax sets are engineered to bolt to a known platform, which saves fabrication time. The second split is size: -8 AN and -10 AN flow more than smaller lines, so match the size to your pump and injector demand rather than over-plumbing a stock setup. Note the price spread reflects this - a full 150ft braided roll sits near the top of the range, while individual pieces fall much lower.

What else you need

Braided hose is useless without ends. Pair it with Fittings and Adapters to terminate and transition your runs. If the reason you are upgrading lines is more fuel delivery, look at Fuel Pumps. When you have the engine bay open, Gasket Kits and Oil Filters are worth checking off. Browse the full Engine Components section for the rest.

Fitment and ordering

Fitment data is present on 20 products, covering years from 1995 to 2025 and makes including Subaru, Harley-Davidson, GM, Pontiac, Nissan and Toyota - treat this as a sample of covered vehicles, not the full list. If you are unsure a kit fits your car, call fitment help at 813-535-5801 or reach us through contact us. Every order ships free, and Affirm and Katapult financing is available.
