JMCHstore Stainless Steel Mini Bike Gas Tank 4x11" 2L — Vented Cap & Fuel Petcock

JMCHstore’s 304 stainless steel mini bike gas tank is a compact 2L (0.53 gal) replacement tank built for minibikes, go-karts and small powersports engines requiring a 4" x 11" cylinder.

This lightweight, corrosion-resistant cylinder is designed to fit popular small engines and minibike frames — including Predator 212, Coleman CT200/CT100 series, Baja, Massimo and many TrailMaster and Realtree models. Precision-assembled with argon arc welding and polished to a mirror finish, the tank pairs a vented cap and CNC vent with a fuel petcock to deliver reliable fuel flow and easy maintenance without adding excessive weight.

Will this tank fit my engine or mini bike model?

It fits a wide range of common small-engine minibikes and go-karts that accept a 4" diameter by 11" long cylinder and use a similar petcock and cap arrangement. Check your existing tank dimensions and mounting clearances before ordering.

• Dimensions: 4" (100 mm) diameter × 11" length.
• Capacity: ~2L / 0.53 gallons.
• Compatible with Predator 212 and many Coleman, Baja, Massimo, TrailMaster, Realtree, Motovox and Mototec models.
• Sold without mounting hardware — verify bracket and bolt fitment on your frame.

How durable and corrosion-resistant is the stainless steel tank?

The tank is made from 304 stainless steel, chosen for strength and resistance to rust when used with typical gasoline. Welded with argon arc techniques and polished, it resists road wear and keeps a clean appearance over time with routine care.

• 304 stainless construction for rust resistance and longevity.
• Argon arc welding for strong, leak-resistant seams.
• Polished mirror finish for corrosion protection and aesthetics.
• Vented cap reduces pressure build-up that can stress seals and welds.

How does fuel control and venting work on this tank?

The tank includes a fuel petcock for straightforward on/off/reserve control and a vented cap plus CNC-manufactured vent to maintain airflow. Proper venting prevents vacuum lock and supports steady fuel delivery to carburetors or fuel systems on small engines.

• Included fuel petcock enables easy fuel shutoff and reserve selection.
• Vented cap and CNC vent maintain pressure balance and consistent flow.
• Vent tube allows routing away from heat sources or rider areas.
• Designed for gravity-feed systems used on most minibikes and go-karts.

What comes in the package and what else will I need?

The package ships with the stainless steel tank, a vented fuel cap with vent tube and a fuel petcock. Mounting hardware, brackets, hose and hose clamps are not included, so plan to reuse or purchase fitment parts separately.

• Included: 1× 304 stainless tank, 1× vented cap with vent tube, 1× fuel petcock.
• Not included: mounting hardware, fuel hose, hose clamps, frame brackets.
• Recommended: verify hole sizes and petcock thread type to match your bike.

Who is this for: Riders, mechanics and DIY builders who need a compact, corrosion-resistant replacement or upgrade tank for minibikes, small go-karts and compact powersports rigs. Ideal for anyone running Predator 212-style engines or common minibike platforms who wants a durable 2L solution with reliable venting and a polished look — provided you can supply or fabricate the mounting hardware to suit your frame.
