So I unscrew the cap and there is a tremendous amount of pressure released, is this normal, I am in FL( 90DEG) , so much so that it blew the cap off and broke the attached chain????? Also after filling up at the gas station and going home, I wanted to fix the broken chain, when I removed the cap gas started coming out of the fill neck !!! I'm thinking that it may have to do with how the ski is sitting on the trailer ! It's parallel to the trailer but does slope down when i hitch it on the vehicle. One other thing I noticed was while on the water the gas gauge was 1 bar above E and the alarm came on shortly after, but at the station it only took about 7 gals, I thought I had a 16 1/2 gal tank ! does this seem right? I don't like gas tank/gage issues, they make me very nervous !!! Any advice would be greatly appreciated, thanks.
