I just purchased a 54 Chevy 3600 with a 235 straight 6 in it. I thought i was having fuel pump problems. After checking it out and finding nothing apparently wrong with it i put more fuel in the tank and it fired right up. I was wondering if anyone knew if it was just one of the limitations of the old mechanical fuel pumps that you need to keep a certain amount of fuel in the tank to help with the pressure or if it may be going out on me?
