Vulcan, a leading motorcycle in the motorcycle world right now, has tremendous and advanced features. Many motorcyclists desired to have Vulcan due to its solid performance and ruggedness. The Vulcan 900 series is also an incredible addition from Kawasaki that grabs the motorcyclist’s attention.

The robust engine, higher capacity fuel tank, powerful battery, and other necessary parts are pure class on this bike. Despite all these benefits, Vulcan 900 collapsed due to some common errors. Among them Vulcan 900 fuel pump problems are alarming. The common problem is frequent fuel pump failure.

Today, we’re going to highlight all the problems, symptoms, and solutions that help your long run avoid further hassles. In addition, other necessary information related to the fuel pump will be shared.

Overview Of Vulcan 900 Fuel Pump Problems

Overview Of Vulcan 900 Fuel Pump Problems

The most common issue with the Vulcan 900 fuel pump is frequent sludge buildup, which in turn causes corrosion buildup. After finishing the long mileage ride, the fuel pump is stuck with some unwanted sludge or mud. If you don’t clean them, the sludge stays on them and gradually gets corroded. Therefore, this is an initial problem with the Vulcan 900 bike.

Secondly, an unclean pump filter too fast is another typical yet concerning fuel pump problem faced by the Vulcan owner. The fuel pump gets dirty due to rough riding off-road. In addition, dirty fuel or oil causes lots of problems including bad fuel pumps.

Thirdly, cracking inside the fuel pump is another common fuel pump failure. The fuel pump fails due to electrical defects, not using recommended fuel, and contamination of fuel. Fourthly, oil pump leakage can be seen which destroys pump efficiency and regulates the pressure inadequately.

If the fuel can’t flow adequately through the pump, the engine lacks fuel which reduces engine performance. As a result, the air and fuel ratio hampers which in turn burns excessive gasoline.

Symptoms Of Fuel Pump Problems

In this section, we will give some insights into how fuel pump failure affects the entire motorcycle’s performance. However, the following are the telltale signs that tell you your Vulcan 900 bike fuel pump fails completely.

Poor Engine Performance

The first symptom of a faulty fuel pump is poor performance. It happens due to a lack of transferring adequate fuel to the fuel pump. When adequate fuel doesn’t enter the engine, the engine fails to serve better performance.

Lengthy Or Delayed Vehicle Start

A difficult or lengthy start is an intriguing sign that directly indicates Vulcan 900 bike’s fuel pump has a problem. It happens due to insufficient oil or gas supply to the necessary parts evenly and faster.

In addition, a worn pump can’t push the fuel too hard or loses pressure. As a result, the engine gets inadequate gasoline to run smoothly. And if the engine is starved of fuel which in turn causes start failure.

The Engine Gets Heated Frequently

The common engine problem is overheating. The engine overheats frequently for various reasons. Entering insufficient fuel into the engine and other engine-related components is a serious cause of engine overheating. Unfortunately, a faulty fuel pump can’t deliver the right amount of fuel which causes significant damage, and a lack of fuel causes overheating.

Decreased Fuel Economy

A better flow of fuel saves fuel ultimately. As problematic fuel pushes too much or too lean fuel to the engine and internal components, it’s common to burn more or less fuel than normal. It ultimately costs lots of gasoline and costs you more. As a result, you can’t get the expected mileage with the expected fuel. 

Engine Stalling

Usually, the engine stalls when necessary fuel can’t be delivered. We already know that reduced fuel causes engine overheating and thus, overheating causes the engine to stall and over time, misfiring.

Power Loss

Another very alarming sign of a faulty fuel pump is ultimate power loss. It is encountered especially when you drive steep inclines or drive under stress, and you suddenly experience a loss of power. And here, the fuel pump failure is considered the major culprit.

Whining Noise From The Fuel Tank

Another common yet brainstorming symptom of a bad or faulty fuel pump is harsh noise like whining noise. This sound comes from the fuel tank due to a broken fuel pump or starting to fail. 

Causes Of Fuel Pump Problems In Vulcan 900

Unfortunately, fuel pump failure or problems occur without noticing or alarming. In Vulcan 900, fuel pumps get stuck with several problems for various reasons. The most possible cause for the fuel pump problem is an electrical failure. Let’s understand the possible reasons behind this issue.

Contaminants Fuel Pump

Contamination in the fuel tank is the most typical but significant cause of fuel pump failure. Indeed, the fuel pump is located in the fuel tank. Hence, it is directly connected to the tank. Sludge, dirt, debris, and other harmful objects get stuck on the fuel pump which causes sludge buildup. And later, it produces rust to decrease the pump life. As a result, you will encounter lots of issues with the Vulcan 900 fuel pump.

Backdated Fuel Pump

When the fuel pump gets old, it suddenly creates problems. Today’s advanced motorcycle manufacturers use upgraded fuel pumps. Hence, if your fuel pump has been used for a long time and you take care of it very little, it causes different issues.

Stuck Or Clogged Fuel Filter

Over time, the fuel or oil filter gets jammed with different unwanted objects or dirt. As a result, fuel can’t go on its way with purification, resulting in the engine’s tending to misfire and the pressure being low. In the meantime, you notice poor mileage, check engine light turn on, etc.

Electrical Faults

The fuel pump has a connection to the electronic channel. Simply put, if the brushes and commutators get damaged, the motor needs to boost more current to create the same pressure. As a result, the pump damages gradually.

Fuel Deficiency

We put this reason into 5th place. Start My Car found many fuel pumps damaged due to lack of fuel or fuel starvation. We all know how crucial it is to balance the exact fuel to the engine. Engine performance mostly depends on how the fuel is delivered to the engine and other internal components.

Steps To Troubleshoot Fuel Pump Problems

We all want to face less hassle in maintaining, but problems arise now and then. Fortunately, every single issue has a solution. This is why there is a step-by-step guide to follow.

Step 1: Gather all the necessary tools to complete the project.

Step 2: Replace the fuel pump to identify the exact issue.

Step 3: You can use the fuel pressure gauge to test the exact fuel pump problems.

Step 4: Check the electronic connectors to ensure whether it is bad or not.

Step 5: Check the pump fuse and if any fuse is worn out, replace it.

Step 5: Check and replace the pump relay.

Step 6: Clean the pump filter and replace the fuel line connectors.

Step 7: Then, change the pump seal.

Step 8: And finally, fix the ECU nut to complete the process. After that, install the fuel pump in its place again.

When To Seek Professional Assistance For Fuel Pump Repairs

If you notice any inconvenience or faulty signs of the fuel pump and find it serious, take professional assistance. Otherwise, it will bother you afterward. So hire a professional if you want to eliminate further damage.


So you now know all the Vulcan 900 fuel pump problems with solutions. The fuel pump is a crucial component that directly affects motorcycle performance. Though the Vulcan 900 is a top-notch, and high-end featured motorcycle right now, it’s also caught up with fuel pump mystery. Its fuel pump gets corroded frequently with sludge build-up.

The fuel pump of this motorcycle is caused by many reasons. Among them, electronic connection faulty, using the wrong fuel, and clogged fuel filters are remarkable. However, if you are stuck on determining the exact fuel pump problems, read this guide.
