Actually, I did not replace the accelerator lines. It was the short individual return lines coming from each carb that "T" together that I mistakenly spoke of. What I did with the accelerator lines was, I blew through them with compressed air and checked the functionality of the check valve. It all seemed to be clean and function properly so, I let them be. These tiny lines where grey, but they did not look like they had the clear inner liner like the other grey fuel lines did. Do I need to replace these?
