You're the owner of a luxury line that's the pride of Toyota Motor Co. What kind of Lexus do you drive? Car or SUV? Sport or luxury? Straight gas or hybrid? All Lexus vehicles use fuel injection technology, with a high pressure system consisting of a tank, lines, a pump, filter, and injectors. Pressures inside the fuel system of your Lexus can reach anywhere between 50-100psi. Every component relies on the other for maximum performance – when one part goes it can trigger a chain reaction making the other parts of the system work harder than they should. Even something simple like a faulty gas cap seal can wreak havoc on your vehicle's performance.

Replace your gas cap seal today for under $20. Better safe than sorry, right? Mark Automotive makes quality OE gas cap seals that will last until the next scheduled change. This particular seal needs to be inspected and/or replaced at least every 90,000m – or once every 5 years. Don't worry, we carry all the big important parts for your Lexus's fuel system too! Need a new pump? Purchase a brand new fuel pump from Pilot. Pilot's OE fuel pumps are some of the least expensive units in the industry, but last just as long as the original manufacturer parts would. All parts sold here are direct replacement components that require no modifications or retro-fitting to install.

      What is a Fuel System 'Throttle Body'?
      A throttle body assembly is an integral part of a fuel-injected engine's air intake system. Its function is to regulate the amount of air that flows into the engine - accounting for factors such as throttle (gas pedal) position, idle speed, cold start warmup, and more. To perform these critical tasks, the throttle body is bolted in place between your engine's intake manifold and air filter housing. A hinged metal plate inside the throttle body (known as a butterfly valve) opens to let more air in as the gas pedal is depressed. Because fuel injection systems are inherently computer controlled, information from various sensors mounted on the throttle body allows the vehicle's engine management system to determine the optimum fuel flow rate as based on multiple conditions.

      Does My Vehicle Have a Mechanical or Electric Fuel Pump?
      From the earliest days of the automobile, fuel pumps have existed to draw fuel out of the fuel tank and move it into your engine's combustion area. (A note for the purists: some very early cars, like the Ford Model T, used "gravity feed", which required the fuel tank to be mounted higher than the engine. These cars could only climb steep hills by ascending them in reverse!)

      How To Replace An In-Tank Fuel Sending Unit
      A Fuel tank sending unit is a term for the mechanical assembly inside your fuel tank which measures the level of liquid in the tank, then reports its findings to the fuel gauge on your instrument cluster. All sending units contain a "float" piece which does just what it describes - floats atop the surface of the fuel. Many automakers design the float piece as an attachment on a hinged arm that pivots as the level in the tank rises or drops. Others design the float piece as a cylinder that rides up and down around a metal shaft.

      How To Replace Fuel Injectors
      Fuel injectors spray fuel directly into your engine’s cylinders during the intake stroke when a piston moves down to allow air and fuel to fill the cylinder chamber. When injectors are malfunctioning, leaking, or have failed completely, they will cause rough engine performance, poor idle, reduced power and economy, and exhaust that’s rich enough in unburned fuel to damage expensive exhaust parts such as oxygen sensors and catalytic converters.
