i replaced all the fuel lines, and now i cant gas to the engine. i have two tanks with twin 23 engines. I have two lines going into the water separator one from each tank and then two lines coming out of the water separator with the hand pumps in them, one line going to each engine. I pulled the water separator and it was about half full of gas. So i filled it up and the engines cranked up and ran for a minute no problem then died. Seems im not getting any gas from the tanks the the separator. Go i need to install those hand pumps between the tanks and separator? Seems there may be air getting in there but i cant figure out where. Any ideas?

change balls or go wit a fuel pump

My primer bulb is after my water seperator. No issues with mine.
