DIY with fuel pump replacement is also feasible, but it takes some mechanical know how along the right tools. Naturally, how difficult this is will vary based on your car. With a lot of vehicles, the fuel pump is placed within the tank and that simply makes things more difficult because most often than not the tank has to be lowered whether or not it has to even go anywhere but south! But it can be done if approached with the right preparation and focus.
Gather fuel line disconnect tools, a jack to lift the vehicle with, and a fuel pressure gauge so you can test the system afterwards. Typically replacing a fuel pump can take between 2 and 4 hours, in the case of it being a bracketed fuel pump is position dependant as well with some pumps on top and others on the bottom side of the tank.
To begin, relieve the fuel system pressure by removing the fuel pump fuse or relay and allowing the engine to stall. This allows you to disconnect the fuel lines and not have any fuel pressure, reducing the chance of them spraying fuel. Then, the battey is detached because any electrical discharge while working on a fuel line isn't safe, as this can spark an explosion.
After you've taken the pressure off, gutter removal might be needed. That necessitates unbolting the fuel tank straps and gently dropping the tank down onto a jack. The fuel pump may be accessible via a panel under the rear seat or in the trunk, however this varies from vehicle to vehicle.
Since you need to access the fuel pump, you should first remove any of the fuel lines, electrical connectors or other components attached to the pump. However, remember to annotate the orientation of these connections so that you don't mix things up in reassembly. At that point, you will be able to take out the old one and replace it with a new fuel pump estate.
Prices for fuel pump replacement range widely, but a new fuel pump generally costs $200 to $500, and its specific cost is depending on the type of vehicle you drive as well. That is why you have to spend you $400 for the labor, and this is why many people will prefer doing it themselves.
It still requires basic safety measures like working in a well-ventilated area so you don't huff too many fuel fumes and making sure there's a fire extinguisher within arm's reach. Fuel is a very flammable, and an one small error could lead to disastrous consequences.
Commenting on the precision and safety needed in maintaining a vehicle, Elon Musk said: "The devil is obviously in the details for all mechanical work." And that is excellent advice, particularly in regard to a fuel pump change --where getting it wrong could mean your car won't start the next time you try or worse — depending on how clever a fixer you are.
