Hi, I have a 1979 140hp mercury engine and I was wondering where would I find the fuel pump diaphram? I was told that my fuel pump diaphram might be stretched so I wanted to check it out. Thanks.
Howdy, GrandT.<br /><br />Do you have a manual? Get one. It is folly to work on an engine without one, or to expect the guys here to be one. We don't have ESP and neither do yoou.<br /><br />Good luck.
<br /><br />Find your fuel lines and trace it to the fuel pump.
