Clay, I just checked my 91 model and mine is set up with a tee in the hose that feeds the pee hole. It's tied in at the back of the engine, on the starboard side, just above where the hose comes out of the water jacket. The hose for the pee hole then travels up over the heads of the starboard cylinders and back down to the pee hole. The hose for the gauge travels down and around the port side and joins up with the cables and fuel line coming out the front of the engine.
I hope this helps.
