ATRACYPART Tecumseh Gas Fuel Tank Replacement 36863 — Fits 4.5–6.5 hp OHH50/OHH60 Engines, High-Density PE with Screw Cap

ATRACYPART 36863 is a direct-fit replacement gas tank with cap engineered to restore leaking or damaged tanks on Tecumseh 4.5–6.5 hp engines (fits OHH50, OHH60 and related models).

If your mower, generator, or other small engine powered equipment is losing fuel or showing brittle, cracked plastic around the original tank, swapping in a robust aftermarket tank is a fast way to get back to work. This 36863 fuel tank from ATRACYPART is molded from high-density PE polymer, shaped to match Tecumseh mounting points, and supplied with a screw cap so you can install the part immediately. It replaces OE numbers 36863 and 36752 and lists compatibility with a broad set of Tecumseh models including OH195EA/EP/SA/XA, OHH45/50/55/60/65, OHSK55 and others.

How does this tank prevent leaks compared with older OEM tanks?

The tank is manufactured from a reinforced polyethylene blend that resists fuel swelling and vibration fatigue better than many original units. Mold tolerances are optimized to align with factory mounting holes and seals, reducing stress points that cause cracks. You’ll notice fewer flex lines and a smoother surface where seals and screws meet.

• High-density PE polymer construction for chemical and vibration resistance
• Improved molding around mounting points to lower stress fractures
• Includes screw-on cap for a secure seal out of the box

Will this part fit my Tecumseh engine model?

This fuel tank is designed to be a drop-in replacement for specific Tecumseh engines and matches the OE part numbers 36863 and 36752. It fits a wide range of overhead valve and horizontal shaft models commonly used on walk-behind mowers and small equipment. Double-check your engine model stamp or the original part number to confirm compatibility before ordering.

• Compatible with OH195EA, OH195EP, OH195SA, OH195XA and similar OH195 variants

How easy is installation and what tools will I need?

Installation is straightforward for anyone comfortable with small-engine maintenance: remove the old tank, transfer the fuel lines and mounting hardware, and bolt the new tank in place. No specialized tools are required—basic wrenches and pliers are typically sufficient. If the cap or vent hose needs replacing, those items can usually be swapped in during the same service.

• Simple bolt-on replacement—matches factory mounting holes
• Basic hand tools (wrenches, screwdrivers, pliers) are all that’s needed
• Transfer existing fuel lines and cap or use supplied cap if included
