Probably a dumb question so go easy on me please. I pulled the carbs to tear apart and clean and I also replaced the fuel filter, took the tank out to clean it, and took the fuel pump out to make sure everything was good with it. Now my fuel pump has no suction! I pulled the line off of the fuel filter and put my finger over it and nothing. Also, the fuel filter is empty (obviously). I'm wondering if when I put my fuel filter back together if I put that black plastic piece in wrong, or does it matter? Also the suction and discharge nozzles might not have been put back exactly in the same position. I'm pretty sure they are..... when I get home tonight I'll pull it and double check for the little pesky diaphragm. Can someone post pictures of how the black plastic thing goes in or tell me where I can find a diagram. Thanks!
