Chuck:
The coolant pipe portion of the fuel log weldment basically sits right on the top bypass port of the water pump and blocks access. The original racecars running this set-up also blocked off this port, but they didn't run a thermostat so they weren't dead head-ing against the back of the thermostat until it opened. Here's an example of the situation we're up against when running this Comp Fuel log...
In the picture above, you can see the top bypass port with the coolant pipe resting on it. The bottom port is still connected to the pipe running from my Harrison tank. This is the one that will be modified to accept a "T". Both of these ports on the WP are suction.
