Where does one hook up the line for an oil pressure gauge?
I would run a Tee for both gauges
I would also leave the mechanical gauge in the engine compartment for referral purposes.
One doesn't need oil spewing into the cab
If it is mechanical do what Dennis said and keep it in the engine compartment.
I had a capilary tube rub into and spray out all over the floor,seat and me. Who would think a fine tube that size could spay out so much oil.
I put a baker scaffold over the front of my truck and was able to lay on it to access the engine compartment and put a Tee in the sending unit port
