Why do gas caps click?
This part is located inside the gas cap and is what allows small amounts of pressure to be released from the cap in cases where the tank is building excessive pressure. In many cases, the “clicking” sound you are hearing is caused by this pressure valve resetting itself.

Does a fuel return line have pressure?
Thanks! Since the fuel pump is always moving fuel, that fuel it has to go somewhere. That somewhere is either to the injectors or back to the fuel tank. That advantage is a return line provides nearly constant pressure to the injectors regardless of what their actual demand is.
What are the symptoms of a bad fuel line?
Usually a bad or failing fuel hose will produce a few symptoms that can alert the driver of a potential problem.
- Fuel odor. One of the first symptoms of possible issue with fuel injection lines is a fuel odor coming from the vehicle.
- Engine misfires, hard starting, and stalling.
- Fuel leaks.
What lines or pipes connect the engine to the fuel tank?
For example, take your car’s fuel hose — aka fuel line — they’re rubber, metal or plastic pipes through which gasoline passes from the fuel tank, where gasoline is stored, to the fuel pump. From there, fuel is squirted into the engine’s combustion chamber via fuel injection or a carburetor.

Too high of pressure may result in over fueling of the engine. As a result, This can lead to a rough running engine; poor fuel mileage, and black smoke coming from the exhaust. If your regulator is going bad, your car could display several different symptoms.
What happens if your fuel pump is too big?
Too big of a cam for your combination will cause a loss of low end torque and make drivability suffer. Such is the case with fuel pumps, to some degree. The remaining fuel returns back to the tank, but the fuel pressure regulator acts as a restriction to the return line.
