Fuel-Tool: Specialty Fuel System Tools for Fuel-Injected Harleys

Fuel-Tool is a specialty tool brand focused on a very specific problem: making fuel system service and fuel transfer simple on fuel-injected Harley-Davidson motorcycles. Rather than offering a broad catalog, Fuel-Tool concentrates on a handful of purpose-built tools and the replacement parts that keep them working, and the brand's own site, fueltool.com, shows the same narrow focus. The line is built around the factory quick-disconnect fuel fittings found on 2001 and newer fuel-injected Harleys.

Fuel Pressure Diagnostics

When a bike hesitates, stalls, loses power or returns poor fuel economy, fuel delivery is often the culprit. Fuel-Tool's Harley fuel pressure gauges, such as the MC800 with its 100 PSI gauge, 16-inch flexible hose and swivel magnetic mount, tie into the fuel line through quick disconnects so you can read pressure under static and load conditions. For riders and technicians who want to pinpoint a problem before replacing parts, the Fuel-Tool diagnostic scan tool listing is the place to start.

Fuel Sharing and Siphon Tools

Traditional siphoning means hoses, spilled gasoline and the risk of swallowing fuel. The Fuel-Tool MC100 Motorcycle Fuel Sharing System replaces that routine with a no-tools, no-modification connection that installs in seconds. A fuel-injected Harley acts as the host bike, and fuel can be transferred to any motorcycle that has run dry. It is also useful for draining a tank before seasonal storage or maintenance. Browse the Fuel-Tool siphon options to see how it works.

Check Valve Repair Kits for Harley-Davidson

The factory fuel line check valve and its O-rings can dry out or degrade over time, and ethanol-blended fuel is a common cause of leaks at the quick disconnect. Fuel-Tool addresses this with rebuild and replacement items, including the MC400 check valve rebuild installation tool, MC450 replacement hooks, MC900 replacement collar kit, MC200-5 check valve O-rings, and the MC600 fuel line male end rebuild kit with MC600-5 O-ring packs. Rebuilding the check valve can avoid the labor of pulling the fuel pump from the tank just to replace the whole assembly. These parts are gathered under Fuel-Tool motorcycle products.

What to Consider When Shopping

• Model compatibility: Most Fuel-Tool products are designed for 2001 and newer fuel-injected Harley-Davidson models, so confirm your year and model before ordering.
• Match the kit to the job: Gauges diagnose, rebuild kits repair, and replacement O-rings keep tools and fittings sealing properly.
• Keep spares on hand: O-rings are consumable, and fresh ones help prevent leaks at the fuel line connection.
• Fuel safety: Work away from sparks and open flame whenever you handle gasoline.

For owners who do their own wrenching and want to diagnose and repair fuel delivery issues accurately, Fuel-Tool offers a focused set of tools designed around one platform.
