Hi,
I'm trying to remove the fuel pump in my 2002 Mazda Tribute. I took off the two fuel lines and the wire bracket. But I can't get the light blueish ring off to pull out the pump. I read that you should be able to turn it off. I could not physically turn it so I even tried using a screw driver in the notches going around . I thought I could hammer the screwdriver to get the ring to turn, but no luck. Actually chip small peice off. Is there a special tool or is it a matter of strength?

 

I assume you know to turn the ring counter-clockwise? Since you've come this far I would guess you know that, but just to make sure....

I don't know about Tributes specifically, but I do know from past experience that there is usually some slop in those rings and that they may need to be approached from different sides to get them to move w/o binding.

And yes, I'm sure there is a specific tool, like a bung wrench that would removed them. Probably only at your local Ford or Mazda dealer though?

 

I had a piece of wood that some one sugested yo use. I tried to hit the ring at different angles several times with the hammer and wood. I finally broke it loose and then finally got it off. I got all the electical harnesses and fuel lines off. I extraceted the pump and got the new pump . The instuction did not really say much. I angled the new pump in the tank which had to be held down because it is spring loaded as I tried to evenly place the ring on and screw. I used the hammer and wood to get the ring on real tight. Put everything back on, hooked up the battery and the truck started right up. I then went to clean up and found a platic bag in bottom of box. I then realized that I was supposed to place a rubber washer ring on pump before installation. I had to do everything again. And the pump was full of gas and one electric harness would not come off. Long story short I got it all back and I am running smooth.
