I just finished replacing the fuel pump in my 2001 STS, and refused to pay $100 for a special tool. It REALLY helps to have a tool (particularly when re-locking the ring). So I made my own and wanted to pass this along as a tip.

Yes you can hammer at all corners of the ring with a brass punch, but this is WAY easier.

Go to home depot and buy a $2 pipe union (4" drainage pipe). Then dremel out some slots to look like this:

I sprayed the locking ring with PB Blaster and let it sit a few minutes. Grabbed a brass door hinge pin and a hammer. Came right off.

Penetrating oils are great for helping to get the ring off, but back on you need to push on all tabs to jump over their locking bumps. That part is MUCH easier if you can push on all tabs at once. Hitting on each tab is hit & miss...

That pipe union doesn't look familiar, but it DOES look like a water pump removal tool; or close.
I'm going out to the garage and see if that's the case.

For some reason, I have about 6 water pump removal tools.

The number of "fingers" is the giveaway for the fuel pump lock ring tool vs. the Northstar water pump removal socket.

Harry, y'all want to create your own picnic/wine basket and meet us halfway for lunch in some Southeast Cecil County park sometime soon?

Yup, the pump tool is too small.

Jim, I'll get back with you.
