Need the mower model number. is this gas engine or the diesel? With diesel engine, need to run a test line from the fuel pump inlet, back into fuel tank filler opening, bypassing the tank outlet hoses and filter hoses up to the electric fule pump If this is a gas engine, we need try something else!
Z25 is not model number. ??? Don't open new question, please reply to this one, You say metal filter? You sure this is not the electric fuel pump?
ZD25 ? Three cylinder diesel. it has two filters and an electric fuel pump.
