Yes Paul , I did .... before the hump was bonded on , 2 large holes big enough to get your hand through were cut ...not sure of the size but the biggest hole saws I had , so about 6'' at a guess ...the front hole allows access to the bottom of the stock Spitfire filler cap , the rear hole allows access to the roundall light to change the bulb or get to the wiring and fixings .
A trip to Hypehose got me two large 90 degree bends that when suitable cut and sleeved with a stainless steel insert , gave me a continual rubber filler hose from filler cap to tank . All accessible when interior in as I intend to change the way the rear cockpit panel fits so it can be removed easily when cockpit sides are in place properly .
