REPLACEMENT PART NUMBER:MC-400 MC-300

QUICK AND CONVENIENT INSTALLATION: Specifically designed for the rapid professional installation of fuel check valves. The complete set of tools ensures a good seal and maintains pressure, and allows for the reassembly of the check valve without the need to remove the fuel tank. Simple maintenance without the need to replace the entire check valve and fuel pipeline.

THE SET INCLUDES: 10 high-temperature resistant Viton O-rings (5 large-sized, 5 small-sized), 5 corrosion-resistant stainless steel springs, 10 installation hooks (5 large-sized, 5 small-sized), and one MC-400 professional installation tool. All components are neatly stored in a sturdy and durable storage bag, making it convenient to carry and suitable for use in garages or on trips.

HIGH-QUALITY MATERIALS: Made of stainless steel, hardened tool steel and Viton O-rings, it features excellent high-temperature resistance, fuel degradation resistance and engine vibration resistance. The Viton O-rings can withstand extreme temperatures ranging from -40°F to 400°F, have a longer service life than standard rubber seals, and ensure long-lasting leak prevention protection under harsh riding conditions.

PRE-INSTALLATION TIPS: 1. Before installation, use clean oil or fuel to lubricate the O-ring and the tool tip to prevent tearing and ensure smooth sealing without leakage. 2. Carefully clean the valve body and remove all old rubber debris to prevent tiny fragments from causing the new seal to fail. 3. The new O-ring may be smaller in size than the expanded old ring that was removed. This is because under the pressure of the fuel, the new O-ring will expand, forming a tight, 100% leak-proof sealing effect.
