Oil and fuel pressure transducers identical?

I see some pictures on builders websites that show oil pressure transducer and fuel pressure one are different. One uses one wire and the other two. I have carbureted engine and my senders are identical. Both bigger in diameter which means I have to use upper and lower ports in the manifold. Is that normal or am I missing something?
 
Transducers...

Mine (from GRT) look the same but have a different pressure ranges -
0-140 psi for OP, 0-80psi for FP.
The case is ground, so the OP only uses one wire because it is mounted to the engine. My FP transducer is connected to a non-metalic fuel line, so I had to run a ground wire in addition to the signal wire.

Dennis I looked closely and found some markings on nipple hex. 0801 16 on first one an 0002 100 on the second which I guess means 16 psi and 100 psi. Both are IE-411 single terminal. Could anybody confirm that?
