I did the same thing with my tailwheel, after hearing Jim Hill explain the similarities between the KR's tailwheel the needle in one of those old record players that used a horn instead of an amplifier. And since my fuel pump is mounted on two "studs" sticking up out of the fuselage floor, I can easily add a pad under the fuel pump if it gets to be a problem. I will confess that shortly after replacing my mechanical fuel pump with a Facet on my Karmann Ghia, I quickly found some isolators to put between the chassis and the pump, because the pump was really obnoxious in the passenger compartment, even though the pump is bolted to the floor pan just below the fuel tank up front. These isolators are typically used to mount the fresh air fan in the late seventies and eightie's VW vans, as well as other locations on VWs. I'm sure there are equivalents throughout automobile land from other manufacturers as well. They are solid blocks of rubber with two 6mm (1/4") studs embedded http://home.hiwaay.net/~langford/isolator.jpg , and they will really quieten down that fuel pump. And they only weigh a half an ounce each. You can get them at you local "aftermarket" VW emporium, or maybe even the VW dealership, if you don't mind ordering and waiting a few days. Maybe this is the answer I should have given the first time around, but I'm going to see if maybe I won't find the sound of the fuel pump to be somewhat comforting, if not informative...
