    Fuel Pump removal

    All the 1999 STS manual says I need a collar ring removal tool to get the fuel sending assembly out of the tank.

    Does anyone have a work around?

    You should probably post this in the Seville/Eldo forum. The job can be done without the tool from what I have seen posted but you need to be careful about pounding the ring out. You will also need a new gasket.

    Yea, I guess that would make more sense. Anyone have this tool for sale:

    I've used an hammer and a screwdriver and just tapped the retaining collar (ring) to turn it.

    Nope. The tank was still sealed until I loosened it. Putting back on was the same. Had it finger tight, then by the time I had to tap it in place, it was sealed. Besides I WAS careful when tapping it on and off.

    If your concerned about sparks you could use a brass drift instead of a screw driver.

    Out of the hundreds I have done I have used many methods and never had a concern of sparks.
    It isn't really a spark generating process.
    Be sure to have something handy, like a fire extinguisher just in case but....

    OK, the lock ring wasn't a big deal at all. Fuel pump replaced.

    Car starts now but I still have the same issue I started with I cannot throttle up and she stalls (And the overpressure valve pops). Throws code P0101.
