When you say 'cut away a section of pipe', I assume you mean the supply
pipe that enters the tank, so that the connection of the Fluidmaster
can be close to the bottom of the tank.
But the new gadget needs to be solidly connected to the input
pipe, not on a flexible mount, surely?

(I had assumed the web site was going to show an adaptor for fitting on
the end of the shortened input pipe to provide a threaded connection to
the gadget.)
