My FIA Comp Fuel Log/Water Neck Bypass Modification..
The following pictures show what I came up with.
This picture shows the fuel log/water neck and “T” tube fabricated to tap into the bypass port of the water pump and draw coolant from the Harrison tank.:
This photo shows another view from the back of the fuel log/ water neck. On the water neck, you can see the extra pipe that was added to draw coolant from the intake outlets and return it, via the “T” tube back to the water pump bypass port. I like how my fab guy did this so cohesively such as it retains the construction style of the overall weldment..:
This photo shows the water pump. You will see that the top bypass port has been welded shut. This port cannot be accessed due to its proximity relative to the water neck. The bottom port has a rubber junction to accept the “T” tube:
The following is a few pictures showing the entire thing bench-fitted to illustrate the concept. You can see that a small ¾” ID rubber elbow is all that’s required to complete the bypass plumbing. Also pictured is the thermostat housing from Jim Inglese that is coupled to the exit of the Water Neck. The long tube coming from the “T” tube runs up and connects to the Harrison Tank:
This is what it packages like on the engine. I'm quite pleased so far:
Next up is to install it and see if it actually works!!
