Well, I did not have any crow's foot wrenches when I did the SD. And, you would normally be correct, in that you can't do the job without them.

However, on the SD there is a hose nipple to the immediate right of the pump. Disconnect the hose (from the tank IIRC), and remove the hose nipple with a standard wrench. Then, with the hose nipple out of the way, you can now get a standard wrench on the flats of the pump.

No crow's foot required.

This is on the 126 with the 617. The 115 may be different.
