After a while, some of your car's parts may fail due to overuse. Because BMW engines are so reliable and work after 20 years as they did when they were first started, some of the other car parts might not be able to keep up.
A clear example is the fuel pump, which can fail either due to old age or due to some other issues like overheating, debris getting sucked into it and inadequate fuel supply. Before changing the fuel pump you should check it throughly to see if it's really the pump's fault or some other issue that is hindering your proper use of the car.
If the check reveals that the fuel pump is done you can follow this DIY and replace it yourself, it's not that complicated.
First of all order a new, original fuel pump for your car and get everything you need at hand. Here's what you need: the fuel pump, a fuel pump seal ring, a flat head screwdriver, a hammer, gloves, protective goggles, paper towels and a marker.
Step 1: Make sure the area is well ventilated in order to avoid accumulating gas vapors. Also check to see if you still have your radio code at hand, make sure there is no portable lights or anything electronic/electrical in the vicinity and make sure the gas tank isn't more than 3/4 full.
Step 2: Remove the backseat by pulling from the marked areas in photo no 1. Remove the (-) connector from the battery.
Step 3: After the seats are off, you will see a section of padding cut into a circle. That's where the fuel pump is located. The pump is covered by a metal lid held together by 4 philips screws. Loosen those to get to the fuel pump.
Step 4: The fuel pump has 2 hoses going into it (one is for outgoing one for return), a pump harness, the level sender harness and a collar ring attached to it as you can see in photo no 2.
Step 5: Disconnect the wiring harnesses.
Step 6: Disconnect the fuel hoses. When doing this make sure to have the aforementioned paper towels at hand in case you spill some gas. Do this step slowly in order to avoid getting gas in your eyes or other sensitive parts.
Step 7: Mark the way the pump was oriented in order to put the new one in place the exact same way.
Step 8: Unscrew the collar ring counter-clockwise using the flat head screwdriver and a hammer (photo no 3)
Step 9: Remove the pump by pulling upwards the whole housing. Take your time. The seal ring should come off along with it.
Step 10: Install the seal ring first and then insert the new fuel pump inside the tank.
Step 11: Tighten the seal by doing step number 8 clockwise.
Step 12: Connect the fuel hoses and make sure they are tight. Don't apply too much pressure, you don't want to deform the connectors for the fuel lines.
Step 13: Connect the wiring harnesses (photo no 4)
Step 14: Reconnect the (-) battery cable and start the car. Check to see if everything is ok.
Step 15: Put everything back together in reverse order.
ENJOY!
