I am restoring this '66 fleetside and on the very back of the engine block by the distributor hold is a very small pipe coming off a brass fitting. Since the motor was out of the truck, I do not know what it is for. Any help is appreciated. Is it vacuum or for some gauge. maybe temp

For some reason, my brain cells tell me this was a oil pressure tap location. It might have come from the rear cam bearing and gone to a gauge, or had a sending unit in it. I could be wrong on this.

So it goes to the oil gauge in the dash, but the other end has a brass fitting also that attaches to rear of the engine and that in turn must go down to the cam bearing area? I guess it will work when I get it all back together.

If it has two fittings coming from the same port, one is for the mechanical gauge and the other would be for an idiot light showing no oil pressure. A buddy of mines' Vette had that dual set-up,

I would do a picture, but that would mean I would have to actually learn how to put it on this site. which is probably a real project on its own. I did take lots of pictures for my reference when putting it together.

I think this may have gotten confusing. The hole in the block is merely a access point to the oil system. You can use it for whatever you want. You can plug it, run a mechanical gauge off of it or stick a electrical sending unit in it. It doesn't do anything....it's just there!
