Fuel pump install
 

Help. I start on the trunk, remove padding. Remove 4 screws to lift plate to get to pump and lines. I now need to disconnect battery lines.

I am stumped on removing the white connector (non-ground) I can't see if there is a tab that needs to be pushed in. I can't feel one. I had no luck squeezing the sides and trying to remove it.

the tab will be on the left side of the connector ...squeeze and use your other to help it along... make sure your garage is well ventilated...

Done!

I hope I didn't screw anything up!

When I had the assembly out, the float fell off, so I put it back on. I swear the rubber gasket/sleeve didn't want to get pulled down all the way to the top of the pump, so I left it as far as I could get it.

The car hesitated, got fuel, then started.

Note, I did this on like 1/8 of a tank of fuel, I will have to see what happens with a full tank. I did not replace the big seal/gasket at the top of the tank like the manual says. When I asked my Mazda mechanic what part I would need, he just mentioned the pump, the filter, the 0-ring and plastic collar, and the little metal piece that holds end of the filter down.

I just did mine yesterday too, but then I was going over the Workshop Manual. I'm missing the O ring. Now I have to open the sucker back up and find an o ring for it. Wondering would any O ring work or is there a specific one?

There is a specific one. this is the one between the top of the pump and where it connects to the fuel line, with a little plastic sleeve, and rubber on the outside? You should have gotten the Mazda part kit that includes the o ring and the plastic sleeve.

Or you should have reused the existing o-ring (not recommended).
