Hi, I have a merc 115 (1975) and have recently put the tanks in the front where they originally were, I rebuilt the fuel pump and purchased a new bulb and fuel lines. When I run the motor it idles nice but as soon as I hit WOT the engine bogs to a stall. The primer bulb is soft so I reprime it and start again, this time at half throttle, I can hear and feel the engine spit and cough until more fuel is delivered but the outcome is the same, soft bulb.<br />I thought it could be vapor lock so I disconnected the main hook up just after the bulb and pumped until a steady stream of fuel came out but it did no good. I have a quicksilver tank and a wal-mart $35 tank (both quick connect) and both were tried, both did the same thing.<br />When the tanks were in the back I had no problem until I started messing around with them, now even when I put them in the back I get the same result...What did I do wrong?<br />Help me! PLEASE!
