Fuel Systems 101: Everything You Need to Know
What Types There are
There are four different configurations, generally: in-tank pumps with a sucking a jet pump, in-tank pumps without one, semi-in-tank pumps, and pump sets.
A fuel tank, plus a fuel pump, a fuel filter or filters, and either a carburetor (in older Lexus models) or fuel injectors (in newer ones).
What They Do
They work together to help keep gas flowing to the engine.
How They Work
It's relatively simple. The tank holds gas, while the pump draws it out and sends it to the engine. The fuel filtration system captures byproducts in the gas, along with other impurities, and keeps them from entering the engine. The carburetor or injector system works with the pump, oxygen sensors, and an emissions control system to manage what gas gets sent to the motor.
Signs of Problems with One
Whichever your Lexus model has, it isn't permanent, unfortunately; its parts can wear out and/or fail entirely, usually after a long life of use. To help prevent trouble moving gas, be sure you inspect for issues regularly. Look for:
- Stalling and problems starting
- A sputtering engine and sudden loss of power (especially when towing or driving uphill)
- A whining noise coming from the fuel tank
- Worsening gas mileage
- A temperature gauge that reads hot
- Random surging
See any of these, and you should do that fuel system inspection. Replace any parts that its results indicate. Before you buy any, however, be sure they're genuine.
