Oil pressure sending unit

Just wondering if the proper oil pressure sending unit #50 or #80?

Also, does anyone know the thread size for the adaptor that goes between the sending unit and the pressure relief valve.

Thanks.

Found a picture of the part. Just trying to figure out the threads.

Jordan..See if the threaded area is tapered..that will tell you it is a pipe thread..for liquids such as oil or water think pipe threads..It is probably 1/4"NPT(National pipe thread )or 3/8"..all easily obtainable..

It 18 tpi, so as Alex said, NPT. It appears to be a parrallel thread, as your picture and mine have a copper washer under them. These things go on the hole size for volume flow, so it will be 1/4 NPT (BSP is 19 tpi) The other end fits the ford sender.
