3. Include the length when necessary. Example: 16, 17, 18, 20, 22

Gas Cap and Fuel Gauge leaking in hot weather

I am told this is normal and can be avoided by only filling the tank to 3/4s. Is this accurate advice? Tambo attached the following image: [87.86Kb] Edited by Tambo on 07/17/21 - 5:22 PM

Otherwise, visit the tank manufacturers web site for instructions on avoiding the problem. The six gallon tank fill cap on our Whaler has a fill cap with an adjustable vent valve incorporated. The valve can vent the tank when it "inflates" from warm weather temperatures. We just push it down and let the fumes escape. Regardless of how much pressure has been in the tank it has never leaked. The temperature in our garage where we store the boat has been as high as 120F and possibly higher. I assume you have tightened the tank gage? It may have a defective gasket. Butch

The days of "fill it till it is full" are over. The new caps do vent and also release pressure at >3 psi. As I said to Tambo, I replaced my new tank cap with a traditional vent cap. 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT
