HFP-SK1 is a premium OEM replacement in-tank fuel pump strainer kit engineered to restore primary filtration integrity and guard the high-pressure fuel pump on Arctic Cat and Ski-Doo snowmobiles. Serving as a direct-fit replacement for factory number 861302400, this high-capacity intake filter sock snaps onto the base of the stock internal fuel pump module. It features precise application compatibility across an extensive range of two-stroke electronic fuel injection (EFI/SDI) and four-stroke sled platforms spanning the 2003 through 2012 model years, including the Arctic Cat Firecat (500/600/700), Sabercat, Crossfire / CF / CFR (500/600/800/1000), M-Series (M5, M6, M7, M8, M1000), as well as the Ski-Doo GSX 600 SDI, MX Z 600 HO SDI, Expedition (600 HO SDI, V-1000, V-1300, V-800), and Skandic (SUV, SWT) lines. It systematically resolves critical fuel starvation bugs caused by clogged or collapsed intake filter socks, such as high-RPM engine bogging, lean-burn popping under heavy load, hard cold starting, and fuel pressure drops in deep powder or trail riding conditions.

Snowmobiles operate under intense temperature swings, high chassis vibration, and long periods of off-season storage. During summer layups, moisture condensation forms inside the fuel tank, causing fuel phase separation and releasing tank scale, silt, and varnish. These contaminants sink to the bottom of the fuel cell where the primary intake strainer sits. Over time, the original factory strainer becomes choked or structurally degraded, starving the fuel pump core and forcing it to run hotter and pull higher electrical amperage, which can lead to complete pump failure in remote backcountry trails.

HFP-SK1 cures these suction restrictions by providing a fresh, high-flow first line of defense for your sled's fueling module. Manufactured with an advanced multi-layer gradient woven mesh design, this intake filter sock captures microscopic debris, ice crystals, and tank scale before contaminants can enter the pump impeller cavity or damage downstream precision fuel injectors. The structural frame and internal attachment collar utilize high-performance synthetic rubber seals and chemical-resistant polymers engineered to remain flexible and crack-free when continuously submerged in modern pump gas, high-octane race fuels, winter storage stabilizers, and ethanol-blended fuels.

Features & Benefits:

• First-Line Intake Protection: Traps silt, rust scale, and fine tank debris before it can enter the electric pump core, preventing cavitation and pump wear.
• Gradient Multi-Layer Mesh Design: Engineered for maximum surface area and high fuel flow rates to eliminate mid-range hesitation and high-RPM fuel starvation.
• High-Performance Synthetic Rubber Collar: Built with an industrial-grade FKM mounting interface that resists swelling, hardening, or cracking under freezing sub-zero trail conditions.
• Extends Fuel Pump Lifespan: Maintains uninhibited fuel intake flow to keep the pump motor cool, reducing electrical current draw and protecting the stator system.
• Exact Baseplate Geometry: Meticulously dimensioned to snap directly onto the factory internal fuel pump inlet barb for a secure, leak-free mechanical lock.
• Cost-Effective Maintenance Solution: Replaces the high-wear intake filter element during routine servicing without necessitating the purchase of a complete, expensive fuel pump module.
