Here's the problem... My 63 runs fine until the fuel gets below 1/2 tank.... then if it is going uphill it sputters and kicks like it is running out of fuel and goes about 20 MPH top speed, but it doesn't stall. Once it gets to the top of the hill and levels out, it catches itself and runs fine again. I guess its a good thing I don't have very long hills in Atlanta! Sitting in the garage, level, it starts and runs fine at all levels of fuel capacity, even at 1/8 tank. The fuel coming into the carb seems clean and the fuel filter is clean, even after a few thousand miles. I siphoned some fuel out of the bottom of the tanks and poured it through a cloth filter and it looks clean with not obvious dirt particles. My theory is that the fuel pickup tube inside the gas tank may have a perforation(s) in it, around the 1/2 tank level, and when I step on the gas going uphill at that level of fuel, and need more fuel pumped into the carb, it starts to suck air, and the engine gets just enough fuel to keep the car running, but not able to go uphill without rebelling. Any other ideas or any experiences with a similar problem? If this is the problem.... Can I get the line out of the tank without dropping the tank, or should I bite the bullet, drop the tank, and it cleaned and resealed, and fix the line as well.... and maybe evening replace all the fuel lines while I'm at it? Where can I get a replacement for this fuel pickup line? Thanks for any advice or guidance on how to do this.
