Hi my name is***** will be glad to help. Check the fuel lines for leaks between the tank and pump that would caus the system to suck in air and check for restrictions. A faulty regulator or check valve can also cause this or transfer pump. Crack loos the bleeder plug on top of the fual filter housing and pump the primer pump until you get straight fuel and no air from the plug. Then tighten the plug and pump until you feel resistance. Then start the engine. LEt me know if you need more help

Crack open the bleeder on the housing to bleed air from the secondary fuel filter after it has been installed dry until you get no air and straight fuel. to bleed the head if empty crack open or remove the fuel line from the housing that runs from the back of the head to the fuel filter housing and pump the primer until you get straight fuel out of the line. Recinnect and then pump until you feel resistance.

Click this link, See PDF page 4. #9 it the hand priming pump and #11 is the bleed screw. Fuel systemCat recommends not filling the filters as the center hole is direct to the pump and any contaminants in your fuel can will not be filtered and go right to the pump.
