Learning How to Replace Fuel Injection In-Tank Fuel Pump
Replacing the fuel pump can be intimidating because you have to drop the gas tank, and of course, gas is flammable, which makes everyone nervous. Back in the day, most vehicles featured carbureted fuel systems, which were later replaced by the overwhelmingly popular electronic fuel injection systems. This changed the process of removing and installing a fuel injector because this shift changed the location of the fuel pump. So if you have an older vehicle, and you are unsure of the type of fuel system you have, get a hold of your vehicles’ car repair manual and use the diagrams to determine which one is equipped in your vehicle. Do this before you attempt to disassemble your vehicle or you might find yourself in dangerous trouble instead of performing quick car repairs.
Prepare the Vehicle- And Yourself- For The Ultimate Drop
In quick car repairs, especially one like this, it is very important that you follow each direction carefully, and that includes making the full and proper preparations for the removal of the fuel pump. First, you have to relieve the pressure in the fuel system. To do that, remove the fuel pump fuse from the fuse block and then start the car, letting the engine run until the car runs completely out of gas. Start the car again and make sure it cuts off to ensure all the gas has been consumed. Next, drain the gas tank. This can be done by suctioning most of the fuel through the filler neck, then lifting the car high enough to access the bracket connection. Use the opening found there to drain as much gas as possible from the tank. This will help you to avoid an injury or spill when the tank is completely removed.
Removing The Old Fuel Pump
Now, in order to get to the fuel pump, you have to remove the fuel tank, which you cannot do by yourself. You will require some assistance from another person in order to do this properly and safely- and no matter how strong and muscular you are- do not attempt to remove the tank by yourself. It is vitally important to refer to the car repair manual at this step of the process to check for manufacturer specifications and recommendations for removing the fuel tank. Disconnect the electrical connector that runs from the main harness to the fuel tank, and then disconnect any hoses that are connected and the fuel filler neck.
While supporting the tank, remove the straps that are holding the tank to the vehicle, and then remove the tank completely. Afterward, remove the brackets from the fuel tank you are disposing of, and attach them to the tank you are using as the replacement. Now you can remove the old fuel pump and filter and proceed successfully with these car repairs.
Installing the New Fuel Pump
Follow the repair manual instructions to install the new fuel pump. It is as simple a putting the new pump in the same place, and in the same manner, as the old pump was situated. Still, it is important to ensure the parts are installed correctly based on your vehicle’s model manual instructions.
Next, place the fuel tank seal o-ring in the fuel tank opening groove, and insert the bracket assembly into the tank without twisting the filter. Install the bracket retainer then attach the fuel tank. Once the tank is installed, and the tank support strap bolts are tightened, reconnect the hoses and lines, ensuring they are correctly attached and secure.
Double check to make sure all mounting brackets, bolts, and connections are secure. Once you are satisfied, you are done. Just install the fuel pump fuse then connect the negative terminal to the battery. Check for any leaks and clean up any spills before you start the ignition. Once you start the car, let the fuel run back through the line for a few minutes before hopping into the driver seat and getting back on the road. Now your quick car repairs are complete!
