Do you repair marine fuel pumps on-site?

Yes – we provide on-site fuel pump diagnostics and replacement for both inboard and outboard engines. Whether it’s a mechanical pump, electric pump, or high-pressure EFI unit, we’ll get your fuel system running smoothly again.

What are the signs of a failing fuel pump on a boat?

Engine sputtering, difficulty starting, sudden shutdowns, or lack of power under load are common symptoms. If your engine stalls after running for a few minutes, your fuel pump may be failing or clogged.

Do you work on diesel and gasoline fuel systems?

Yes, we service both gasoline and diesel marine fuel systems. We handle low-pressure lift pumps, high-pressure injection pumps, filters, lines, and fuel/water separators. All work is done to marine safety standards.

Can you diagnose fuel delivery problems at the dock?

Absolutely. We perform pressure tests, fuel line inspections, and flow checks to find clogs, air leaks, or failing components. Most issues can be diagnosed during a single visit.

How much does marine fuel pump repair cost?

Basic fuel pump repairs or replacements usually cost $250–$600, depending on the engine and accessibility. EFI or diesel injection pump services may range from $700 to $1,500+. We provide quotes after diagnosis.

Do you use marine-rated parts during repairs?

Yes – we only install marine-rated, Coast Guard-approved parts for all fuel system repairs. Using proper components ensures safety and compliance with U.S. marine standards.

Do fuel pump repairs come with a warranty?

Yes, our fuel system repairs come with a 3–12 month labor warranty. New pumps and filters include manufacturer warranties. You’ll receive full documentation for your maintenance records.

Engine Heartbeat

Restore Your
Full Power.

If your boat bogs down at full throttle or struggles to start, your engine is starving. We diagnose and replace failing fuel pumps with USCG-certified marine units, ensuring consistent pressure and reliable performance.

Pressure Testing

Guessing is expensive. We hook up a digital pressure gauge to your fuel rail or Schrader valve to measure PSI under load. This confirms if the pump is weak or if there is a blockage elsewhere.

Mechanical & Electric

Whether you have an older carbureted outboard with a diaphragm pump or a modern fuel-injected inboard with a high-pressure electric cell, we service both systems expertly.

USCG Compliance

Never use auto parts on a boat. Automotive pumps can spark and cause explosions in a boat's bilge. We strictly install ignition-protected, marine-grade pumps that meet US Coast Guard safety standards.

Diagnostic Steps.

Finding the starvation.

Load Test

A pump often works fine at idle but fails at speed. We sea-trial the boat or use a dyno to test fuel pressure when the engine is demanding maximum flow.

Vacuum Check

Sometimes the pump is fine, but the line is clogged. We test for "High Vacuum" on the inlet side, which tells us if your anti-siphon valve or fuel tank vent is blocked.

Electrical Audit

For electric pumps, we check voltage drop. Corroded wires can starve the pump of electricity, causing it to run slow and burn out prematurely.

Installation

We replace the pump, gaskets, and O-rings. We also inspect the VST (Vapor Separator Tank) filter, which is often the hidden culprit in modern outboards.

Common Questions

Can I just replace the diaphragm?

On older 2-stroke outboards, yes. We can rebuild the mechanical lift pump with a new rubber diaphragm kit, which is cheaper than buying a whole new assembly.

Why is my electric pump whining?

A loud whine usually means the pump is working too hard (clogged filter) or the internal bearings are failing. It is an early warning sign that failure is imminent.
