The supply will come from the front of the intake manifold (need hose to connect 2 barb fittings). The return will tube (3/8" id) fill feed into the 3/8 pipe tube and be connected to a 5/8" hose running to a tee in the heater hose. (work in progress-may finish after dropping in the engine) Hope the compression fittings and copper tube will hold up. Figure the rubber hose will provide some flex for durability.
Most likely would have bought the Full Throttle setup, but wanted to get this this going, and with bigger lines TODAY.
Thanks for all your help guys.
Oh, the extra fitting on the top 1/2 tee is for my temp gauge sensor (thermocouple) stowed in the engine bay till I drop this in.
