While you never really see much of it, the fuel tank is perhaps the second most important part of any vehicle (the first being the engine). It's where fuel is stored, and as we all know, every car needs fuel. But the tank itself is only a part of the fuel dispensing system, a complex system that sprawls from the tank to the engine cylinders, where the air-fuel mixture is ignited to create power for driving your car. To understand how it all works and how to care for it, let's start by taking a closer look at the tank.
Usually, a car fuel tank has two main pipes connected to it: an outlet pipe and a filler pipe. The outlet pipe has a fitting for a fuel line connection; through it, the pump draws fuel. It sits a couple inches just above the tank's bottom, preventing sediments from being pumped out of the tank and into the fuel lines-a safety measure. Meanwhile, the filler pipe is exactly what it sounds like; it connects to the outside gas cap, allowing fuel to enter the tank when you're loading up.
Additionally, fuel tanks also contain a drain plug at the bottom so that they can be cleaned and drained when and if necessary. Why? Because despite the tanks being made from the highest-quality, and most corrosive-resistant metals, they're still susceptible to deterioration from corrosive agents in the fuel. They're also susceptible to rust as the tank ages. Corrosion, rust, and regular wear and tear can deter a tank from performing and functioning as well as it did when you first bought your car. If left unchecked, even the most minor holes and leaks may escalate into major maintenance problems for your fuel sending system as well as your engine.
How do you avoid all this with your car fuel tank? Simple: regularly do a visual check-up on it to inspect for any type of damage. And while you're at it, check out some of the fuel sending system's parts that also need regular inspection, like the fuel sending unit, the fuel pump, and the relay. Why? Because these parts work in sync with one another, and if one part is either broken or close to failure, again, you're risking damage to both tank and engine. And you certainly don't want to have to handle those expensive and daunting maintenance issues.
Besides regular inspection, there's another thing you can do to ensure that your fuel tank is working at optimum condition. In the first place, your car should be installed with a high-quality tank-which coincidentally, is available right here at Parts Train.
