What It Is

This is a replacement cap for 5-gallon racing fuel jugs, specifically designed for Scribner, EGS, and similar rigid plastic fuel containers used in motorsports, lawn equipment, and off-road vehicles. It seals the jug opening to prevent leaks and spills.

Fitment & Compatibility

Before buying, confirm your jug brand and cap size. This cap fits Scribner and EGS 5-gallon jugs with a standard 2-inch threaded opening. It will not fit most consumer gas cans (e.g., Blitz, VP Racing) or metal cans. Measure your jug’s neck outer diameter: if it’s roughly 2.5 inches, this cap likely fits. Check for a flat sealing surface—some older jugs have warped threads that cause leaks. Not compatible with vented or push-button caps.

Key Things to Know

• Material: Made from durable, chemical-resistant plastic, but may crack if overtightened or dropped in cold weather.
• Installation: Simple hand-tighten; no tools needed. Avoid using a wrench—over-tightening can strip threads or damage the seal.
• Leak potential: The gasket is effective for upright use, but tipping the jug on its side may still leak. Not spill-proof for transport.
• Common gotcha: This cap lacks a built-in vent. If your jug requires venting for pouring, you’ll need to add a separate vent cap or loosen the cap slightly.

Should You Buy It

Buy this if you need a direct replacement for a lost or broken cap on a Scribner or EGS racing fuel jug and don’t require a vented or spill-proof design. It’s a budget-friendly, functional fix for garage or pit use, but skip it if you need a cap for a different brand jug or demand leak-free transport.
