There is a check valve in the in the fuel filter housing that tends to go bad and acts the worst when the fuel is cold and is more diffecult to pull through the line. Changing of the fuel filter is the first thing to try, being sure you remove the old filter seal and installing the new on properly. I put grease on the oring to make sure it stayed in place while reinstalling.
Hope this helps and I hope that the check valve is not bad.
