Fuel System Parts and Air Intake System Components

Why CBT Auto Parts Is Where Serious Owners Buy Their Fuel System Parts

CBT Auto Parts stocks fuel system components for everyday commuters, work trucks, and diesel fleets alike, and every listing is built around the same standard: it has to match what the manufacturer originally fitted, or beat it. That approach is what separates a genuine car fuel system upgrade from a part that merely looks right in a photo.

Buyers come back for three reasons:

• Fitment first. Every part is checked against make, model, and engine code before it goes live, so you are not left guessing whether a listing actually suits your vehicle.
• OEM quality as the baseline. Aftermarket does not mean a compromise here. Components are sourced to meet or exceed the tolerances of the original fuel and air intake parts they replace.
• Global reach. Orders are packed and shipped to addresses worldwide, with tracking provided from the moment a part leaves the warehouse.

Whatever sits under this fuel system parts collection, from a small PCV valve to a full common rail assembly, the same fitment and quality checks apply.

Fuel Delivery and Storage: Keeping Fuel Moving From Tank to Engine

These are the components that store fuel and physically push it toward the engine, and they take the most wear over a vehicle's life.

Fuel Pumps

A failing fuel pump shows up as hesitation under load, hard starts, or a car that simply will not crank. This range covers standard and high-pressure fuel pump options for petrol and diesel applications, including inline units and popular fitments for Ford, BMW and Mini platforms. Pairing a new pump with a fresh fuel filter is the cheapest insurance against repeat failure.

Fuel Tanks

Whether the original tank has corroded through or you are fitting a long-range tank for a touring build on a Hilux, Ranger, D-Max, Jimny or BT-50, this section carries both OEM replacement tanks and aftermarket long-range options built for extended range off the beaten track.

Fuel Lines

Cracked, brittle, or leaking fuel lines are a safety issue, not just a performance one. This range includes braided fuel line, OEM rubber and metal line, and fittings for classic builds, daily drivers, and heavy trucks, so the line running from tank to engine stays sealed under pressure.

Fuel Pressure Regulators

Performance builds or dies on fuel pressure. This category stocks adjustable regulators from Turbosmart, Holley and Aeromotive alongside OEM replacement units, giving tuners and daily drivers alike the ability to dial in consistent pressure under boost or load.

Diesel Lift Pumps

Duramax and Powerstroke owners running LB7, LBZ, LML, or 6.0 platforms rely on a lift pump to feed the injection pump at the correct pressure. This section covers replacement and upgraded lift pump options built specifically for that demand, protecting far more expensive injection components downstream.

Filtration: Protecting the System From Contamination

Nothing shortens the life of a fuel system faster than unfiltered fuel or air reaching the engine, which is why filtration sits at the center of this collection.

Fuel Filters

This is one of the most searched categories in the entire range, and for good reason: a clogged fuel filter causes stalling, poor acceleration, and eventual pump failure. Coverage spans passenger vehicles like the Mazda3 and Falcon through to Hilux primary and secondary filters.

Fuel Water Separators

Diesel engines are especially vulnerable to water contamination, and this range is built for commercial and heavy-duty applications, with coverage for Volvo, Hino, Kenworth, Freightliner, and Isuzu NPR trucks that need a dedicated water separator ahead of the fuel filter.

Air Filters

The engine air filter here is a different product from a cabin air filter, and this section keeps that distinction clear. Replacement elements are listed by make and model, including popular Hilux fitments, to keep unfiltered air and debris out of the intake.

Air Cleaner Assemblies

Classic trucks, hot rods, and heavy commercial vehicles often need the full housing, not just the element inside it. This range covers custom and OEM air cleaner assemblies for Mack, Hino, Freightliner, F100, and F150 builds where the housing itself is part of the restoration.

Injection and Common Rail: Precision Fuel Delivery for Diesel and Petrol Engines

Modern injection systems run on tight tolerances, and a worn nozzle or pump throws the whole system out of balance. Full injector assemblies are catalogued separately under the Engine and Powertrain section, while this collection focuses on the surrounding components that support them.

Injector Nozzles

Precision matters more here than almost anywhere else in the system. This range covers Bosch, Delphi, and Perkins nozzles for common rail applications, sized correctly for diesel platforms including the 2KD engine family.

Injector Pumps

Strong demand here comes from 4WD diesel owners running 4JB1, TD42, and VP44 platforms. This section stocks both mechanical and electronic injection pump options, built to restore correct fuel timing and pressure on older diesel engines.

Common Rail Components

Acting as an umbrella for the wider common rail system, this range includes Cummins and Bosch common rail injectors, along with supporting fuel pump components for VW, Cummins 5.9 and ZD30 diesel platforms.

Airflow, Sensors, and Intake Control: Reading and Regulating What the Engine Breathes

Air intake system performance depends on sensors reporting accurate data as much as it depends on physical airflow. Intake manifolds, which route that air into the engine, are catalogued under Engine and Powertrain, while the components below sit downstream of that manifold.

Throttle Bodies

A dirty or failing throttle body causes rough idle and hesitation on acceleration. This range covers replacement throttle bodies and throttle position sensors, including common BMW X5 fitments, for both cleaning and full replacement jobs.

Mass Air Flow Sensors

Few components in this collection see more search demand than the MAF sensor. This range covers replacement sensors across most makes, and it is worth noting that "mass air filter" searches are usually looking for this sensor rather than a physical filter element.

MAP Sensors

Working alongside the MAF sensor, the manifold absolute pressure sensor reports intake pressure rather than airflow volume. This section carries replacements for both petrol and diesel applications where a MAP sensor, not a MAF sensor, is the correct fix.

Air Intake Hoses

Silicone and turbo intake hoses connect the intercooler to the throttle body under boost, and any leak here costs power immediately. Coverage includes popular hot hatch fitments such as the Golf R, MK7 GTI, and Abarth.

Turbo Actuators

Wastegate and VNT actuators control boost pressure directly, and failure here often mimics a failing turbo. This is a smaller, more specialised range built for diesel and performance petrol applications where actuator failure is the actual root cause.

PCV Valves

A stuck or worn PCV valve drives rough idle, oil leaks, and rising oil consumption, and it is one of the more commonly searched fixes in this entire collection. This range covers popular fitments across Kia, Subaru and Volkswagen platforms.
