Do you repair marine fuel pumps on-site?

Yes. We diagnose and replace fuel pumps on inboard and outboard engines at your slip, dock or storage yard, or at our San Pedro shop: mechanical pumps, electric pumps and high-pressure EFI pumps. We test pressure, vacuum and voltage first, so you know what has failed before anything is replaced.

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?

Labor is $150 an hour, plus a one-way trip fee by distance for work at your boat ($30 in San Pedro up to $110 in Newport Beach). Most fuel pump replacements take 1 to 2 hours plus the pump itself; EFI high-pressure pumps and diesel injection pumps cost more in parts and are quoted after diagnosis. You get a written estimate before any work starts.

Do you use marine-rated parts during repairs?

Yes. On gasoline boats we install only marine-rated, ignition-protected fuel pumps and fuel hose that meets Coast Guard rules, never automotive parts, because a spark or a fuel leak in the engine compartment can start a fire or an explosion.

Do fuel pump repairs come with a warranty?

Yes. Our workmanship is warranted for 90 days from the invoice date; new pumps and filters carry their manufacturer's warranty. The invoice lists the work done and the parts installed, for your maintenance records.

Marine Fuel Pump Diagnostics & Replacement

Marine fuel pump diagnosis and replacement at your slip, dock or storage yard from Marina del Rey to Newport Beach, or at our San Pedro shop. We test fuel pressure, inlet vacuum and pump voltage to find out whether the pump or a clogged filter, blocked vent or corroded wire is at fault, and we quote any replacement before the work starts.

We work on mechanical diaphragm pumps on older carbureted engines and on high-pressure electric pumps on fuel-injected engines. On gasoline boats we install only marine-rated, ignition-protected pumps, never automotive parts. Our workmanship is warranted for 90 days from the invoice date; parts carry their manufacturer's warranty.

About this service

Engine Heartbeat

Restore Your
Full Power.

If your boat bogs down at full throttle or struggles to start, your engine may be starving for fuel. We diagnose and replace failing fuel pumps with ignition-protected marine pumps that meet US Coast Guard rules, for steady fuel pressure and reliable running.

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. Unlike marine pumps, 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 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 an electric fuel pump, 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 boat fuel 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 outboard fuel pump (the 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.

Full Throttle Ahead.

Have your fuel pressure tested.

Choosing the Right Marine Fuel Pump

A marine fuel pump is not interchangeable with an automotive part. Marine fuel pumps are ignition protected (SAE J1171), so they will not spark in a bilge where fuel vapors can collect. Whether your engine uses a mechanical diaphragm pump or a high-pressure electric pump, the replacement must match the OEM pressure and flow specification for your engine.

Our marine pump service and repair starts with measurement, not guesswork: pressure testing under load, a vacuum check on the inlet side and a voltage drop test on electric pumps. That tells us whether the pump itself has failed or whether a clogged filter, blocked vent or corroded wire is the real cause. To help us prepare, note the engine make and model, and whether the problem appears at idle, at full throttle or when starting.
