ok so i bought a new fuel line as i was restoring the boat and everything was good with the line and fuel. so today as im headed in to the marina the boat crapped out so i thought it was just running out of gas as the tank was low. so i put the line on the other tank and it turns but wont start and as i connect it and then prime it i hear a little air coming out at the connection between hte pump and tank. so my question is why would something like this happen and should i just get a new line or is there something i can do? thanks. you guys really helped wiht everything on my boat. here's one more.
