Allstar Performance Primer Bottle 16.9 oz — angled tapered filler tube, alcohol-fuel compatible

Allstar Performance 16.9 oz. Primer Bottle is a durable squeeze bottle with an angled, tapered filler tube designed to quickly and cleanly prime alcohol engines by fitting into carburetor fuel bowl vent tubes.

If you work on hobby race cars, go-karts, or other small engines that run alcohol-based fuels, having a purpose-built primer bottle makes starting and tuning easier. This compact 16.9-ounce bottle combines a flexible, long-lasting plastic body with a cap that includes an angled filler tube and tapered tip so you can deliver fuel right where it’s needed without spills or fumbling. The design focuses on control and reach so you can prime even recessed carburetor bowls.

How does the angled filler tube help when priming carburetors?

The angled filler tube lets you access tight or recessed vent tubes without having to disassemble the carburetor or hold the engine at awkward angles. Its tapering tip creates a snug fit in small openings, reducing spills and improving accuracy when transferring fuel.

• Accesses difficult-to-reach vent tubes with minimal disassembly
• Tapered tip forms a better seal to limit drips
• Angled shape improves line-of-sight and hand clearance

What makes this primer bottle durable and reliable?

The bottle body is molded from resilient plastic that withstands repeated squeezing and handling in workshop or pit environments. The cap and tube are secured to resist leaks, and the materials are selected to tolerate alcohol-based fuels used in many racing engines.

• Sturdy plastic resists cracking under repeated use
• Secure cap connection minimizes seepage during handling
• Chemical-compatible construction for alcohol fuels

How much fuel does the 16.9 oz capacity give me for priming tasks?

A 16.9-ounce capacity provides multiple priming operations for small-engine applications before needing to refill, reducing downtime during preparation. The size strikes a balance between capacity and portability so the bottle is still easy to stow in a toolbox or pit bag.

• Enough volume for several priming cycles on go-karts or RC setups
• Compact footprint fits most toolboxes and pit kits
• Transparent or semi-transparent plastic allows a quick fuel-level check

How should I use and maintain the bottle for best results?

Use steady, controlled squeezes to deliver small amounts of fuel and avoid overfilling the carburetor bowl. After use, rinse and dry the bottle if switching fuel types or storing it long-term to prevent contamination; keep the cap closed to maintain the tapered tip shape and prevent dirt entry.

• Prime with short, gentle squeezes to meter fuel delivery
• Rinse before changing fuel types and dry completely for storage
• Store capped to protect the tube and prevent debris buildup

Who is this for? This Allstar Performance primer bottle is aimed at racers, mechanics, hobbyists, and anyone who regularly starts or tunes small alcohol-fueled engines. If you need a compact, durable, and accurate way to add fuel directly into carburetor fuel bowls or vent tubes—especially in tight spaces—this 16.9 oz bottle offers a practical, workshop-ready solution that reduces spills and speeds setup.
