I noticed every once in a while when fueling up my Porsche Cayman 981 the fuel pump stopped at about 3/4 to 7/8 of a tank. I would think it was full and then get in my car and go to drive off just to notice the fuel gauge was not indicating full. i started trying different methods to fill my Porsche joy tank. I found that holding the fuel nozzle at an angle helped comple the fill to the brim and stop at the proper level. Just a tip for you Porsche Boxster and Cayman owners, might even be an issue on the 911’s of the 991 generation. www.radiatorgrillstore.com
