Leaking gas at tank

[jerkputter]

I have a 20 foot pontoon 2000 year model with a 50 HP Mercury that now leaks when I prime the bulb around the connection at tank. It is the 5/16 barb fitting with the quick coupler. It has a small o-ring inside the connector that is bad. I think maybe the o-ring could be swelled a little. Was wondering what size o-ring to buy for this? I just pushed the ball back in the coupler and removed the o-ring to remove. I have an o-ring set but this one is has a larger diameter than the ones I have. Thanks

Its a lot simpler to replace the coupler.

Maybe it's time to replace the coupler, hose, and bulb. especially if it is all 2000 vintage. Regards, old jim

DON'T SMOKE while you are doing any repairs

Re: Leaking gas at tank

I had one connection that was leaking because this hot weather is causing a lot of pressure in the gas lines. I cut and clamped the leak but it started leaking at another fitting until I loosened the gas cap. Fixing or replacing gas lines just wasn't on my schedule for the day.
