Just a heads up, I replaced the fuel filter in my Yamaha F150 motor yesterday, but not before struggling with unscrewing the plastic bowl from the metal cap. I googled this issue and found several posts from owners with the same problem and somebody posted a trick to put the fuel bowl and cap in the freezer for 30 minutes and then try unscrewing it again…I did that and poof it worked!
I guess over some time the gas can cause the plastic to expand just a bit causing it to be near impossible to unscrew it off, lots of horror stories of users trying to use pliers to get it off and breaking the plastic bowl.
Just thought I’d share the trick as it worked great for me!
