attwood High-Output Marine Fuel Primer Bulb for 1/4" Fuel Line — 93014LP7, ethanol-resistant low-permeation design

The Attwood 93014LP7 is a high-output, low-permeation primer bulb that quickly primes 1/4-inch marine fuel lines while resisting ethanol, collapse, and excessive fuel evaporation.

Designed specifically for marine outboard engines and portable fuel systems, this primer bulb combines multi-layer construction with high-efficiency internal check valves to speed priming and maintain steady fuel flow. Built to meet EPA and CARB standards and assembled in the USA, the 93014LP7 works across a wide temperature range and is formulated to resist the effects of ethanol blends commonly used in modern fuels. Its robust design reduces pumping effort and helps prevent the common failures seen in lower-quality bulbs.

How does this primer bulb improve starting and fuel flow?

The 93014LP7 uses optimized internal one-way valves and a multi-layer bladder to establish a reliable suction and push action that moves fuel faster with fewer pumps. That means quicker engine cranking and fewer interruptions from air pockets.

• High-efficiency internal check valves for faster priming
• Multi-layer construction resists collapse under vacuum
• Designed to minimize air ingestion and reduce stalling

Is the Attwood primer bulb suitable for ethanol-blended fuels and harsh marine conditions?

Yes — the 93014LP7 is engineered with ethanol-resistant materials and low-permeation layers to limit fuel vapor loss and inner-layer delamination. Its construction helps preserve flexibility across temperature extremes so the bulb performs reliably whether stored cold or used in hot summer conditions.

• Ethanol-resistant inner materials prevent swelling and breakdown
• Low-permeation layers reduce evaporation and odor
• Temperature-tolerant design maintains functionality in varied climates

What size hoses and systems is this primer bulb compatible with?

The 93014LP7 is made for 1/4-inch inner diameter fuel hose commonly found on small outboards and portable tanks. It is suited for typical marine fuel line setups where reliable priming and regulatory compliance are required.

• Fits 1/4" ID fuel hose without adapters in most installations
• Works with outboard engines and portable fuel systems
• EPA- and CARB-compliant for use in regulated regions

How durable and serviceable is the primer bulb over time?

Attwood designed the 93014LP7 to resist common failure modes like collapse under vacuum, ballooning under pressure, and inner-layer delamination from ethanol exposure. Routine inspection is recommended, but its reinforced construction extends service life compared with generic bulbs.

• Multi-layer construction reduces risk of collapse and bursting
• Assembled in the USA with quality control standards
• Simple inline replacement — no special tools required

Who is this for: The Attwood 93014LP7 is aimed at anglers, weekend boaters, and marine technicians who need a dependable primer bulb for small outboard motors and portable fuel systems. It’s a strong choice when you want a compact, ethanol-resistant, and regulator-compliant priming solution that reduces pumping effort and helps maintain consistent engine starts.
