| I believe I have a fuel pump going bad on my 50 hp Evinrude outboard. It's a 2 stroke, either 96 or 97. I'm trying to order the part online but can't quite find the exact part number. I'm finding lots of 438556, but mine is 438557. Think I could use the 438556? I wondered if it was just a newer version possibly, as it looks very much the same. Any info greatly appreciated. Thanks!

Location: Hayward, WI | It looks like one gets the pulse via hose and the other gets pulse through hole in the back? Does your fuel pump have 2 or 3 hoses attached? |

| You may want to check the fuel check valve just above the tank. In 96 I spent $300 plus on a fuel pump just to discover it was a fail backflow valve in the fuel system. Engine would run when you pumped the bulb then quit when fuel pressure was lost. |

| Ok thanks, I will look into that in the morning. That's exactly what it's doing. Hopefully that's it. I did finally find the correct part as well. Thanks for the info. |
