Hello. all. my fiero has only a dumb dumb light for oil pressure and I'd like to add a real live gauge.. where oh where is the port on the engine that you'd tape into to mount an oil gauge sending unit.. , I'm used to v8's so I have no clue on this 4 cyl and the car isn't here to look at.. and is it 1/4 or 3/8" pipe thread? as I'm sure to keep the dumb dumb light I'll have to use a tee fitting, or is there more than one place to install a sender? chevy v8's there is 2 one at the oil filter and one at the distributor.. any help greatly app.
