Default Oil pressure gauge for M8

Why can't you splice into oil feed line to the heads with a t fitting and then use a regular gauge? Hmm?

This has been talked about and came to dead end. Here is a link to what someone found out about the threads on the M8

Oil feed line pressure to the heads is not the same as pressure to the lifters / crank. You really need to know what the pressure is to the lifters and crank. Oil feed to the heads is for cooling only. No pressure needed, Only flow.
