DIY: Replacing the Fuel Pump

I apologize for not having pictures. I wish I'd thought of it when I did this.

http://www.realoem.com/bmw/showparts...&btnr=16_0317& hg=16&fg=15

Buy a fuel pump, a new rubber ring (p/n 16111179637), and two small hose clamps. You'll also need two golf pencils, some paper towels, a few rags, a Phillips screwdriver and a small Shop Vac.

-- run as much fuel out of your car as possible – some people recommend pulling the fuse that controls the fuel pump and cranking the car to get as much fuel out of the lines as you can, but if you follow these directions I don't believe that's necessary

-- make sure that your car is parked outside, and all the doors/sunroof are open

-- disconnect your battery

-- pull out the back seat and set it aside

-- take a Phillips screwdriver and remove the three screws that are holding the round cover on the right hand side of the car (when facing forward - it'll be the left hand side as you sit in your car facing backwards)

-- disconnect the electrical plug from the top of the fuel pump and push it aside

-- take a Shop Vac and remove as much dirt and dust that has accumulated around the top of the fuel pump as possible; wipe up what you can't vacuum with a paper towel

-- get a handful of paper towels and pack them around the two hoses that you now see coming out of the fuel pump

-- remove the two hoses, and put a golf pencil into each one, sealing it off to keep as much fuel as possible from spilling out

-- remove the large, black plastic lock ring that seals around the fuel pump, and set it aside

-- slide the fuel pump out, wrap it in a rag, and remove it from the car – use caution when pulling out the fuel pump as the rubber ring that seals it may drop off and fall into the tank

-- pull out the rubber ring that seals the fuel pump in the tank (it may remain attached to the fuel pump when you pull it out)

-- take a paper towel and wipe around the edge of the opening in the tank, removing any bits of rubber ring/dirt left behind

-- take the new rubber ring and carefully place it into the opening – it is very difficult to put the ring around the fuel pump and then slide this into the opening; you may crimp the rubber ring and not know it – just be careful that you don't drop it into the tank

-- slide the new fuel pump into the opening, making sure that it's tight against the rubber ring

-- replace the lock ring; this should be hand tight only – you can always (and should) check your work a week or so later to assure that everything is still tight

-- replace the two hoses, using the new small hose clamps

-- reconnect the electrical plug

-- wipe up as much of the fuel that you've spilled as possible

-- replace both the round cover over the fuel pump and your back seat – reconnect your battery

-- it may take a few seconds longer for your car to start, since you've drained some of the fuel from the system

That's it. This should take less than an hour and is one of the easiest DIYs you'll ever do. Replacing the fuel level sensor on the other side of the tank is identical to this, so you get two DIYs for the price of one.

Pictures would have been nice, but you did a good job describing the steps so they aren't really needed.


Great writeup
