Fuel System Parts

The fuel system keeps a steady flow of clean fuel going to the engine based on its requirements, ensuring optimal performance and reduced emissions. This constant supply of the exact amount of fuel at the right time is ensured by a well-coordinated network of components. The filler neck is a starting point; the fuel travels through a pump and filter, is precisely metered by injectors, and finally, arrives in the combustion chamber.

Keeping this process going smoothly isn't merely about avoiding costly repairs down the line. It's about ensuring safety and keeping the high standard of vehicle performance. Whether it’s carrying out regular maintenance, replacing faulty fuel system parts, or making horsepower-increasing mods, we have a wide range of components to meet the specific needs of your engine.

Fuel Tank

This component is not just a storage container for gasoline or diesel. Inside, you'll typically find the fuel pump and possibly valves and sensors associated with EVAP. Fuel tanks and retaining straps could suffer from corrosion or physical damage leading to leaks. If you're on the hunt for high-quality replacements, your search ends here in our store. Our inventory is packed with top-tier products, making sure your car not only performs properly but also aligns with safety norms.

Switching to a bigger or sturdier tank can increase your driving distance and reduce leak risks. If you have your sights set on tackling rough trails or hitting the road for extended journeys, this could be a worthy upgrade. Racing challenges may call for a fuel cell, a safer option compared to a regular tank, which is designed to resist puncturing and spilling gasoline upon impact.

Fuel Pump

Older carbureted cars used a mechanical pump driven by the camshaft. Modern-day fuel injection vehicles feature an electric fuel pump. It is usually located inside the tank, which ensures cooler operation and reduces the risk of ignition if a leak occurs. The pump is part of a module or hanger assembly that incorporates a float and a sending unit, which provides fuel level data to be shown on the instrument panel. A bad fuel sending unit may cause your gauge to act erratically showing an incorrect gas level or being stuck on empty or full.

An attached strainer catches contaminants in the fuel before it flows into the pump. If this strainer fails or becomes blocked, it can potentially result in pressure related issues, damaging the pump and causing drivability problems. The pump can fail due to electrical issues, contamination, or simply wear over time, which can starve your engine of gas and cause it to stall. When replacing it, it's also advisable to change the fuel filter and tank seal. We have all your fuel pump replacement needs, whatever the application. For diesel powerplants, we carry high-pressure fuel pumps and special diesel fuel injectors.

When it comes to power-adding upgrades, it’s quite clear that the more power the engine makes, the higher fuel volume and pressure it needs. Here in our superstore, you’ll find high-performance pumps that provide higher flow rates, making sure everything runs smoothly every time.

Fuel Filter

Some cars rely solely on the strainer for filtering fuel. But for most vehicle models, an inline fuel filter is standard. Since you can't visually inspect it for dirt, it’s wise to swap it out based on the automaker's schedule. How often should you change your filter? It varies, but a rule of thumb is every 30,000 to 40,000 miles. For specifics, consult your vehicle's manual. A dirty filter can mimic the signs of a clogged injector, like reduced gas mileage, starting issues, engine sputters, or power loss. We have replacement filters providing OE levels of filtration as well as their performance-oriented counterparts, designed to provide superior filtration while ensuring the necessary fuel capacity.

Fuel Injectors

Fuel injectors work in sync with the Engine Control Module (ECM) to deliver pressurized fuel into the engine. Over time, they can get clogged with deposits or start leaking due to a faulty seal or a cracked body. This may cause a rich or lean condition, leading to poor engine operation and worse mileage. The lifespan of injectors depends on the quality of gas or diesel as well as the vehicle owner’s maintenance habits. It’s safe to say they might require replacement after approximately 100,000 miles.

The need to swap out one or all injectors is determined by the condition of the rest. If they are in good shape, you may only need to change the faulty one. Yet, if all of them seem aged or have visible wear, it's probably wise to change them all together to prevent upcoming issues. We carry injectors cleaners and replacement injectors that provide OEM quality and function.

If you’ve made upgrades that feed significantly more air to the motor, like installing a larger turbocharger, you need to compensate for a big boost in airflow to maintain the ideal proportion of gas and air. Our selection is rife with performance injectors that deliver higher flow rates and optimized spray patterns and atomization.

Fuel Pressure Regulator

If your powerplant is fully stock, the factory regulator usually does the trick. But when you ramp up to a modified or high-power engine, with performance fuel systems to match, that standard unit might fall short in managing increased fuel flow needs. That’s where our adjustable regulators step in. They allow you to achieve precise tuning when it comes to your vehicle’s fuel pressure, letting you tweak according to your high-performance fuel pump’s peak capacity.

Carburetor

Before fuel injection systems took the spotlight, carburetors were the primary method of delivering gas. As engine demands change with different driving conditions, the carb adjusts the fuel-air mixture, ensuring smooth engine operation. It's essentially a tube that allows air and gas into the engine via valves, with a small opening – the venturi – where the blend is formed, “though various other components are also used to provide extra fuel or air in specific circumstances.” The simplicity of the design contributes to its robustness and long life.

Over time, a carburetor may become clogged due to deposits or impurities in gasoline, leading to poor engine operation or starting issues. Another common problem is the malfunctioning of the float, which regulates the flow of gas into the system, causing an incorrect mixture.

When you bump up to a high-performance carburetor, you get superior control over the fuel-to-oxygen mixture. It can provide increased airflow and more precise fuel metering, leading to improved throttle response and more horsepower, especially beneficial for classic cars or performance-oriented vehicles. Discover our selection of performance and racing carbs, tailored for those with a thirst for power. Ideal for demanding applications, our range ensures your engine gets the precise mixture it requires to deliver peak performance every time you hit the road or track.

What Is a Fuel System Cleaner?

With time and use, the fuel delivery system and combustion chamber can accumulate deposits from gas, which could hinder your vehicle's performance and emission control. This is how a fuel system cleaner works: it contains powerful detergents designed to remove these deposits from the pump, injectors, and lines. The regular use of this additive for fuel system cleaning (approximately once in 3000 miles) can help restore your car's or truck's fuel efficiency and power and extend the lifespan of your engine. We carry trusted brands that supply high-quality fuel additives, including the popular Lucas fuel system cleaner that is formulated for deep cleaning of the entire system and combustion chambers without the use of chemicals harmful to an engine.

A fuel injector cleaner is a targeted solution for dirty or clogged injectors, which could be a potential cause for a misfire. It is designed to dissolve the deposits and residues that build up inside the components over the course of time, disrupting the spray pattern. Our wide selection of cleaners includes a widely-favored product, the STP fuel injector cleaner that uses concentrated detergents, removing residues and restoring performance after just one treatment.
