When they say dual station do they mean twin engine, or Im thinking two sets of gauges monitoring one engine? makes sense if they are half the resistance for dual station because it is additive thats its when you have two sets of gauges monitoring the same engine

Im looking for sending units that are same ranges as MPI 502 stuff but in 1/8 NPT not the 3/8 or 1/2 that is more commonly found. Alot easier because I can put them in metric reducer bushings and bolt right into the LS stuff

Dual station is 2 separate helms.

correct and one example would be a boat with a flybridge for the jist of it

Thats what I was thinking

What is commonly used for oil temp sending units? Found water temp (450-33?) and oil pressure 80psi gauge (240-33)

The North American standard for all gauges is 240-33 ohms (Empty - Full or Cold - Hot) The same scale (240-33 ohms) is used for 0-80 psi or 0-100 psi gauge, or any other type electrical gauge. The gauges and senders are gauges are matched to the scale being used

Thats not the temp scale for water at least, Id assume oil would use the same

Yes, same scale

Not according to the last two links I post, temp senders are difffernt ohms than pressure senders
