On my 383 with new Edelbrock AVS, I am finding some interesting things with the fuel. First is that I am actually pushing the engine on short road hops, not far, and still some on driveway. I recently added a new fuel gauge, suited to the resistance on the OEM sensor. So, added between 6-8 gal of gas, and after some use, found the gauge near zero. Drained the tank to get a read, and there were only 2 gal left.....hmmm, my first surprise. Secondly, as I let the car sit while doing other things.....if it sits for more than about 10 days there is nothing in the fuel filter, and it takes some priming or cranking to start. So my two questions are, for normal screwing around, do you find the beasty using a lot of fuel. And, I wonder where the fuel in the line is going....and guess the fuel pump. Hate to change it when working, since some of the rubbish we get now may not be better than an old piece of junk. Wishing we could still buy USA mfr parts.
