Just got finished watching your nicely done video , got to say it was well thought out and agree that once you get use to fuel injection you never want a carb again , I made a home made fuel injection on mine , its a V6 car and used a TBI off a 84 5.0 , and 2.9 computor off a frod bronco II , on the fuel lines on the return line I used a bulkhead fitting back to the tank , you can pick them up in steel or alum from aircraft spruce , or like you used from a hyd shop , they ar JIC fittings that have the same properties as aircraft fittings , planning on removeing my tank to up grade it with some baffolds , reason is when you have less than a 1/4 tank of fuel and turn the fuel pickup get uncovered and the engine stumbles , any numbers on MPG you getting over the carb ? good to know that holley has that set up in case mine ever dies , have a good one
