Re: 105 GTV Dual Oil Pressure Gauges

Don't, But If you must, be sure to engineer a solid connection braced to 
prevent vibration damage else you will set up a spraying oil mist-er 
that you will regret having installed. Proper brass fittings and gaskets 
are a must. Also make sure pieces don't have too tight a clearance with 
frame, or bulkhead, or firewall and could be damaged if/when engine 
moves against motor mounts. And make sure to clamp lines so they don't 
rub / vibrate against block or frame. If you mount the gauge in/on the 
dash, make sure the flexible (engine movement,) pressurized, hot oil 
line to the gauge running thru your firewall (is grommeted) and running 
into your cockpit doesn't rub and is secure.

Another alternative is gauge mounted outside the cockpit, no oil line in 
the cockpit. Or simpler consider just a second redundant sender 
/electric gauge some of the same under hood prevention of damage issues; 
but none of the hot oil line problems.

Some of the above comes from a 101 Sprint remote oil filter installation 
experience and 101 Sprint mechanical gauge issues 25 + years ago. Me, 
I'd just make sure I had a good electric sender and ground.

Oh, to answer your original question, physics law says pressure is 
constant throughout the system.
