fuel not getting through line. Look at all lines and see where it stops. I'm not sure if the line may be clogged or if I need to get a fuel filter. Trying to figure out how to unclog it or how to determine if it's the filter. It's my wife's car and she needs it for work. I would appreciate any help. Thanks

Hello, I'm Danny.

The fuel filter on your vehicle is non-serviceable. The filter is incorporated into the in-tank fuel pump and will only be serviced when the fuel tank is dropped and the fuel pump is replaced. Since you mentioned you are not getting adequate flow through the line that might indicate a weak or failing fuel pump. I would suggest first performing a fuel pressure test. If you don't have access to a pressure tester most auto parts stores have a tool loaner program and can rent you one. Here is a tutorial showing what is involved for testing:

The fuel pressure specification for your car is 51 psi at idle. Hope this helps and thanks for using 2CarPros.
