Sierra 18-7801 379777 Johnson/Evinrude Fuel Pump Kit Product Description

Keep your Johnson or Evinrude outboard running smoothly on the water with this reliable fuel pump kit. Designed as a direct replacement for the original equipment, it tackles common issues like inconsistent fuel delivery that can leave you stranded mid-trip. Boat owners swear by its durable construction, which stands up to the harsh marine environment, from salty ocean spray to freshwater lakes.

Essential Features for Peak Performance

This kit isn't just a pump—it's a complete assembly that includes the diaphragm, gaskets, and hardware needed for a seamless swap. Crafted with precision-machined components, it delivers consistent pressure to ensure your engine gets the fuel it craves, even at high RPMs. The corrosion-resistant materials mean fewer worries about rust or wear over seasons of heavy use. Unlike flimsy generics, this setup mimics OEM specs for plug-and-play reliability, helping prevent vapor lock and hesitation during those critical moments.

  • Direct-fit replacement for hassle-free installation
  • High-quality diaphragm for optimal fuel flow
  • Reinforced fittings to handle vibration and pressure
  • Complete kit with all necessary seals and screws

Perfect Fit for Your Outboard

Engineered specifically for a wide range of Johnson and Evinrude models, this fuel pump kit restores factory-level performance. It's ideal for 2-stroke and 4-stroke engines where fuel system reliability is non-negotiable. Check your engine's service manual to confirm compatibility, but it's a go-to for classic powerheads that demand authentic parts without the premium price tag. Whether you're prepping for fishing season or trailering to the next adventure, this ensures your motor starts on the first pull every time.

Step-by-Step Installation Tips

Swapping out a faulty fuel pump doesn't have to be a dockside nightmare. Start by relieving system pressure—clamp the fuel line and disconnect the battery. Remove the old pump by loosening the mounting screws and detaching the hoses, then clean the mating surfaces thoroughly. Install the new kit in reverse order, double-checking torque specs to avoid leaks. Prime the system with a few bulb squeezes before firing up. Pro tip: Inspect the fuel lines and filter while you're in there; replacing them together extends the life of your entire system and prevents future headaches.

"Replaced my old pump on a '90s Evinrude, and it fired right up. No more bogging down at WOT. Solid kit!" – Experienced angler feedback.

Long-Term Maintenance for Reliability

To maximize lifespan, run your engine with fresh fuel stabilized for storage, and add a fuel separator if operating in humid conditions. Listen for unusual whining or sputtering—these early signs mean it's time for inspection. Regular checks during annual servicing catch wear before it worsens, keeping you on plane instead of troubleshooting. This kit pairs perfectly with upgraded fuel filters for a bulletproof setup that handles ethanol-blended gas without complaint.

Why Boaters Choose This Over OEM

In the world of marine repairs, aftermarket doesn't mean compromise. This Sierra kit offers the same ruggedness as factory parts but with broader availability and easier sourcing. It's battle-tested by mechanics and weekend warriors alike, delivering value that pays off in reliable outings. Skip the downtime and get back to what matters: chasing horizons and big catches.
