Where is the fuel pump located on a 2003 Cadillac Escalade and how do you change it?

Answer 1

I have just change the fuel pump on my 2003.

Put your cad. on a ramp. you can jack up one wheel at a time if cad. will not run.
You will need the room to work under the cad.


Disconnect the battery,relieve the fuel system pressure, drain tank and disconnect the tank, disconnect fuel evaporative emission lines from the tank,


You can use a siphon hose to drain the tank, take off the hose connected to the back of the tank and drain from there.


There are two retaining straps holding the tank up, unscrew the bolts let the rear of the tank down. This will make it easy to remove the lines from the clip to the tank. do not disconnect the lines from the cad. or the tank, it is enough room to move the tank from under the cad. to the driver side, this will save you some work!


Remove retaining ring with hammer and screwdriver, also replace with hammer and screwdriver. You will have to hit the retaining harder to put it back on.


Pull out fuel pump note place where screen located, replace new fuel pump and rubber seal .


You must change the harness, this should be included in fuel pump kit, the instruction are in the kit.
