take a look at Item # TD9153 at
http://www.aaaim.com/cgi-local/shop991/shop.pl/SID=308430750264/page=TRAN.ht
m#TD9153. If this link doesn't work, go to
http://aaaim.com/cgi-local/shop991/shop.pl/page=start_shopping.htm and
enter the part number in the search. This is a brass bellows unit in nice
housing that moves enough to move a slider potentiometer to change
resistance. Max pressure is 0 -15 PSIG, so sensitivity of movement may be
adequate? Rip out the resistor linkage, etc and retrofit. Hey, it's only $15!

Now, how about somebody posting design specs for machining the O2
valve/seat from scratch.
