Thank you. I'll look tomorrow. Would I need to check this first or the transfer pump/check valve? Thanks.

I recently purchased a 1994 Mack CH613 with a 350 engine. When I let it sit overnight, it is very hard to crank the next day. Once cranked, it will start right up the rest of the day. I searched the forum for others with a similar problem, and the transfer pump or check valve or a hole in fuel line seemed to be the most popular response. Any other suggestions or can anyone further elaborate on this. Thanks in advance.
