Westach sell cht and oil temperature senders with metric threads which are a
direct
replacement for the VDO senders supplied with the Rotax engines. I've replaced
my VDO senders with these as well as fitting 4 x Westach egt senders to
my914 to support the (now defunct) Audio Flight Avionics AFA10 engine management
system. For water temperature I used a Skydrive supplied fitting which sits
in one of the hoses leading from the swirl pot and has another Westac CHT sender
screwed into it.

Tony
