The third line out of the filter on mine is running back to the tank. Originally it should run to the evap but I deleted all that on mine I got all my metal line from the pump to the carb pre bent from inline tube. It had all the fittings on it but im not running a eddy as you can tell.
Nice setup. I would love to run the thermoquad I have but its going on a magnum 360 and I had two options for intakes either the edlebrock airgap or the knock off neither of which fit a spreadbore even with the adapter.
