We'll I've started to run my car more now and it seems that it wont hold gas in the lines to go to the carb. I can't get it 2 crank without putting a little bit into the carb to get it 2 pull. I don't know which one it is! it's got to be either my fuel pump or my pick up lines but i don't have the budget to just buy both and see which one works. Which one do ya'll think it is?
