2007 Suzuki Boulevard C50 Fuel Pump Assembly: The Complete Replacement Guide

The bottom line up front: If your 2007 Suzuki Boulevard C50 is hard to start, sputters at highway speeds, or stalls unexpectedly, the fuel pump assembly is almost certainly the culprit. The 2007 model year uses Suzuki part number 15100-41F30, and replacing it with a quality aftermarket assembly will cost between $30 and $80, compared to over $200 for an OEM unit from a dealer . This guide walks you through everything you need to know, from identifying the correct part to step-by-step installation, so you can get your cruiser back on the road with confidence.

What You Need to Know About the 2007 C50 Fuel Pump

The 2007 Suzuki Boulevard C50 (VL800) uses an in-tank electric fuel pump assembly. This is not just a simple pump—the entire assembly includes the electric motor, the fuel strainer, and in some versions, temperature sensors that monitor fuel temperature inside the tank .

There are two main OEM part numbers you need to be aware of:

  1. 15100-41F20 – Used on 2006 model year C50 motorcycles (sometimes called K6 models)
  2. 15100-41F30 – Used on 2007 through 2011 models, and again on 2013 through 2022 models

Since you own a 2007, the correct replacement number is 15100-41F30 . However, many aftermarket suppliers sell kits that fit both numbers, and some aftermarket pumps are designed to replace all three variants: 15100-41F10, 15100-41F20, and 15100-41F30 .

One thing to pay close attention to: the 2006 model year assembly (15100-41F20) has two temperature sensors, while the 2007 and later assembly (15100-41F30) has one temperature sensor . If you buy the wrong version, your fuel gauge or check engine light may not function correctly. Check your current unit before ordering.

First Signs Your Fuel Pump Is Going Bad

A failing fuel pump rarely fails without warning. Here are the most common symptoms owners report:

  1. Hard starting – The engine cranks longer than usual before firing up. This happens because the pump cannot build enough fuel pressure quickly.
  2. Sputtering under acceleration – When you twist the throttle, the engine hesitates or stumbles. The pump cannot keep up with the fuel demand.
  3. Stalling at highway speed – The engine cuts out completely, then restarts after a few minutes. This is a classic sign of an overheating or failing pump motor.
  4. Whining noise from the tank – A healthy pump makes a faint hum. If you hear a loud whine, the pump is working too hard and may be close to failure.
  5. No sound at all – When you turn the key to "ON," you should hear the pump prime for about two seconds. If you hear nothing, the pump motor may be dead.

If you experience any of these symptoms, do not keep riding. A failing fuel pump can leave you stranded, and in rare cases, a shorted pump can blow the main fuse or damage the ECU.

Which Fuel Pump Assembly Fits Your 2007 C50?

The 2007 Boulevard C50 belongs to the VL800 family. The same fuel pump assembly fits several related models, which is great news for availability. Based on compatibility data from multiple suppliers, the 15100-41F30 assembly fits:

  1. 2007-2011 Suzuki VL800 Intruder C800 / Boulevard C50
  2. 2007-2011 Suzuki VL800C Intruder C800C / Boulevard C50C
  3. 2007-2011 Suzuki VL800T Boulevard C50T
  4. 2013-2021 Suzuki VL800 Boulevard C50
  5. 2013-2022 Suzuki VL800T Boulevard C50T
  6. 2014-2015 Suzuki VL800B Boulevard C50 B.O.S.S.

Some aftermarket manufacturers also list compatibility with 2005 models , but you should double-check your specific VIN before ordering. When in doubt, remove your old pump and compare it visually with the pictures provided by the seller .

OEM vs. Aftermarket: What Riders Are Paying

Here is a quick look at current pricing from different sources:

  • OEM Suzuki part 15100-41F30 from a Japanese parts supplier: approximately $227
  • Aftermarket fuel pump kit (pump with filter, no housing): $29.99 to $79.98
  • Aftermarket fuel pump assembly (complete unit with housing and sensors): $35.50 to $79.39

For most riders, the aftermarket route makes sense. A complete assembly with housing at around $35 to $80 is a fraction of the OEM price . Just understand that aftermarket parts may require slight modifications for perfect fitment . Read reviews carefully and choose a seller with a solid return policy.

Step-by-Step Replacement Guide

Replacing the fuel pump on a 2007 Boulevard C50 is a DIY-friendly job. Expect to spend about one to two hours. Here is how to do it:

Step 1: Prep the bike

Work in a well-ventilated area, away from open flames. Disconnect the negative battery cable first. Remove the seat to access the fuel tank mounting bolts.

Step 2: Remove the fuel tank

You do not need to drain the entire tank, but it helps to run the bike until it is low on fuel. Disconnect the fuel line and the electrical connector at the tank. Unbolt the tank from the frame and lift it off. Place it on a clean workbench.

Step 3: Access the fuel pump

The fuel pump assembly sits inside the tank. Remove the retaining ring (or bolts) that hold the pump flange in place. Carefully lift the entire assembly out of the tank. There may be residual fuel in the assembly, so have a rag ready.

Step 4: Compare old and new

Place your old unit next to the new one. Check the number of wires, the number of plugs, and the physical dimensions . A mismatch here is the most common reason for fitment issues.

Step 5: Install the new pump

Transfer any rubber cushions, holders, or bands from the old unit to the new one if they are not already included . Insert the new assembly into the tank, align the flange, and tighten the retaining ring or bolts to spec. Reconnect the fuel line and electrical connector.

Step 6: Test before reassembly

Reconnect the battery. Turn the key to "ON" and listen for the pump prime. Check for fuel leaks at the flange and fittings. If everything looks good, reinstall the tank and seat.

Step 7: Road test

Take a short ride. Accelerate hard, cruise at highway speed, and check for any hesitation or warning lights.

Common Pitfalls and How to Avoid Them

Many riders make avoidable mistakes when swapping fuel pumps. Here is what to watch out for:

  1. Buying the wrong sensor configuration – The 2006 pump has two temperature sensors; the 2007 and later pump has one . Verify before you buy.
  2. Forgetting the strainer and filter – Some aftermarket kits include the strainer, some do not . A clogged strainer will starve the new pump and shorten its life.
  3. Overtightening the retaining ring – This can crack the tank flange and cause a leak. Follow the torque spec in your service manual.
  4. Installing without checking the electrical connector – If the new pump has a different plug, you may need to adapt the wiring harness. Some aftermarket pumps come with adapters; others do not .
  5. Skipping the pressure test – After installation, verify fuel pressure if you have a gauge. Most VL800 pumps should deliver around 43 psi at idle. Incorrect pressure can cause rich or lean running conditions.
