Yamaha F25ELRY engine is not getting fuel for starting. If I give it a squirt of engine starter it starts right up. May require a couple more squirts until it runs on its own and then all is well. If it isn't left off too long it will continue to start up on demand. Have replaced fuel filter, external fuel line & bulb, gas tank without solving problem. No signs of leaking fuel inside or out. Internal hoses appear in good shape, not cracked. When I pump the fuel bulb gas gets to the carb. I have checked this by removing the hose between the fuel pump? and the carb. Please help. We are camped on St. Joe Bay in Fla and my wife is anxious to go fishing! Thanks!!!
