Apologies if I've mentioned this before in this thread. I have seen those
switches fail in such a way that they would pass the
"beep test" and still not work properly in the circuit. It's best to test them
in-circuit, by checking how much voltage actually
gets to the solenoid (or relay if you have one). Mine was showing a resistance
of about 20 ohms, enough to make the DMM beep, but
not enough to reliably operate the relay.

No special tool for the suction filter, just undo the sump cover and pull the
filter off. You'll probably want a new gasket.
For the high pressure filter, you'll need a tool to unscrew the retaining plug.
I made a simple tool that worked well enough, by
drilling a heavy (approx 6mm thick by 30mm wide) iron bar for a couple of dowel
pins to engage the plug, and letting the bar be the
lever. There is a better home-made tool shown at

While you are in there with the special tool, I would also pull out the dashpot
and relief valve for cleaning. There are a lot of
precision sliding fits in that mechanism, and it only takes a tiny particle of
metal to jam it. The dashpot (and relief valve) have
to move to engage (or release) overdrive.
