55 lincoln 6 volt guage problems

need to sort out fuel and temp guages
have done a lot of searching on here and other forums
they work ok on a bench test , sweeping smoothly across dials
temp unit draws 200 milliamps hot,320 cold
fuel unit draws 200 empty,300 full
can anyone confirm thats correct ?
using a rheostat instead of senders i drive the
temp unit,3 ohms cold ,8 half , 13 hot.
fuel unit 15 ohms empty ,11 half ,5 full
those seem way out to me,a ford fuel sender ( drake or carpenter )
runs 10 ohms full to 70 empty
and i cant find out what temp sender resistance is for 6 volt ford
any ideas anyone ?

 

bump for the saturday night readers ....
