i switched from having logs and snails to open headers on my olds but im not sure how the water lines go. there were 2 lines going to one log on the old exhaust and now on the headers theres only one. i know that one line gets teed off to both headers and the other one goes out the back with a regulator but what about the water coming from the water pump cover ???? any help would be great. pictures would be awesome

4. Jet and V-Drive Water Injected Installation
* Install stainless steel lines to headers.
* Install headers on engine.
* Make sure there is no thermostat or any other type of water temperature control in the housing.
* Install "T" stainless steel control valve in one of the two lines in the thermostat housing. Connect the "T" end to the headers. The lines of the headers should be approximately 2 feet long.
* The other line from your thermostat housing is the by-pass line. Run it overboard with a 1/2" brass gate valve (plumbing type).
* The gate valve is needed to regulate the amount of water you discharge. It also regulates what RPM the water is injected into the headers. Example: gate valve is open and water comes in at 3000 RPMs. In order to make the water come in at 1800 RPMs, close the gate valve approximately 1/3.

Yep that's it. Out of the t and to each header mine has individual lines for each tube.
