fuel probleam
 

i replaced the fuel sending unit and the fuel water separator so disconnected the fuel lines from the tank to the motor now that there both hooked back up i tried to use the primer ball to get her running again but it done seem to be sucking gas in the line i also filled the fuel water sep and nothing what could the problem be

ball has an arrow indicating flow, or a air leak.

yep make sure the bulb is going the right way like said, when I had my V and replace all that stuff I bet it took me 100 squeezes to get the gas?? I like my Fuel Injection now!! Pumps it self!

aside from the other things mentioned...

maybe you knocked the pickup tube off in the tank when you changed the sending unit?
