Reply To: 58 Evinrude 35 Lark Gas Tank Issue

[David Stanton]

By chance do you have the metric fuel line connector meant for Yamaha and some Mercury models? The hole is a little bit bigger and will fit sloppy. The connectors look the same.

If your tank is also a 1958 or slightly newer, it will leak out the vent when you connect the line if the tank is really full, because it’s a 2-way vent, activated by the pn that pushes inwhen you attach the connector. This was corrected a few years later by having the vent be one-way, which did allow the tank to build up vapor presure inside, but they no longer leaked gas if the tank was full. So if you have this early tank, either you don’t fill it quite all the way, or you get a newer tank.
