Factory type 4 dry pipe help

i have a 91 sueptjet with a 760 swap and it has a type 4 dry pipe and I don't know how the water lines are supposed to be routed, my friend who is a two stroke guru helped tune my ski after I did a carb kit, and he said the water lines are routed weird what looks to him he doesn't know how these are supposed to be routed but it has one pisser and it doesn't shoot just water it's a mixture of air and water, not a steady stream which he thought maybe head gasket was gone but he said it's really fast and it performs like the head gasket is fine so I'm hoping someone here knows how a factory type 4 dry pipe is routed so I can check mine. I'm gonna pressurize the water jackets and see if the head gasket is good in a few days but I read how water routing can make or break a setup so I'm curious to see how it's supposed to be routed. I'm new to jet skis so I don't know much, I appreciate the helps. Thanks in advance!

Without knowing anything about your setup, feed line(s) coming from the bulkhead go into the manifold, fitting off of your head goes to bottom rear fitting on the chamber (near the ebox). Top fitting on chamber goes to the very end, stinger fitting on the chamber and the fitting between those to goes overboard. Like Vomitspot said, there have been quite a few threads about it where you can find images if needed.
 
I'll post pictures of it hopefully today, I seen a few but I thought the type 4 dry pipe was routed different for racing purposes, I didn't want to route it how a different style pipe was routed and cause problems

I have installed a handful in the manner listed above, if you wave water injection, things will be slightly different but that's the basics. The real variables are restrictors and flow control valves for the stinger fitting.
