Wheezing!! What a great term Don!!
If that bit of spray bothers you a bit of Silicone slathered {another good term} around the fuel line on the fire wall will cure the problem. I'm kind of hit and miss when it comes to that but I used to do it to all my planes, gotten lazy in my old age. It also keeps the line from vibrating on the fire wall, don't know if that means anything but Ialmost never have any fuel line problems.
Ihate having to reline my tanks so Itry doing everything from having to do it. My gassers get new line every year but I only have three of them so it isn't too bad.
