Hi, can anyone help me with hooking up a mechanical oil pressure gauge on a '71 mustang. The motor is a mostly stock 302, I dont know where to screw in the brass fitting on the block. any help wopuld be appreciated.Thanks,Mike

 

you have to locate your stock oil pres. sending unit should be around the oil filter.the threads are 1/4 in. n.p.t. that means pipe thread you have to remove stock unit and put 1/4in. T in the block use your aftermarket and re hook up your stock unit.
