I am trying to remove fittings from the high pressure side of the fuel pump of my 911SC. There is too narrow an opening surrounding the pump's 17mm nut to fit my open end wrenches around it. The gaps shown here are only 3/16 inch.
Can anyone recommend a tool I could use to hold the pump still while loosening the fittings? ideally, I will use the pump's nut, since I don't want to stress the pump's rubber supports.
