I was taxiing a C172 at ZZZ through the parking area. While moving through the area; I struck a self serve fuel pump with the outboard edge of the right wingtip which resulted in damage to the leading edge; wingtip; and self service fuel pump. After starting my aircraft; I began to maneuver through the parking area in order to avoid another aircraft which was parked to the east of my aircraft on the north side of the parking area. While turning to the east; I began to move slightly to the southern edge of the taxi area in order to allow adequate clearance from my aircraft's left wingtip; and the spinning propeller of the other aircraft. I believed I had sufficiently maneuvered to avoid the other aircraft's propeller and left enough room to clear the fuel pump. However; I did not adequately judge the distance and ht of the pump. I struck the pump moving west to east. The impact caused the aircraft to pivot around the pump. The aircraft stopped in a southerly facing position. I immediately shut down the engine; and determined if we needed to evacuate/evacuation the aircraft. Since there were no signs of fuel leakage; I instructed my passenger to stay in the aircraft. The pilot of the other aircraft had secured her aircraft and was already moving towards my aircraft. We both ascertained the damage of the aircraft. I decided that I should call flight maintenance to apprise them of the situation. It was determined; through discussions with maintenance; that they should fly out and inspect the aircraft. It was determined that the impact with the pump dented the outboard edge of the wing; in addition to cracking the leading edge of the wingtip. The decision was made; by the director of flight maintenance; to receive a ferry permit to fly the aircraft back to ZZZ1. The operator of the airport was contacted regarding the damage to their self service pump. The pump had suffered some damage; as it was now leaning towards the east (direction of impact). A county employee inspected the pump and no signs of fuel leakage were seen from the pump at that time. The self service fuel pump was located at the edge of the taxiway. With the cessna's wingspan it would be impossible to taxi down the center of the taxiway without striking the fuel pump. The fuel pump's ht was measured to be 7 1/2 ft tall.

Title: A C172 WINGTIP STRUCK A SEVEN AND ONE HALF FOOT TALL FUEL PUMP ADJACENT TO A TXWY AT A SMALL AIRFIELD.
Narrative: I WAS TAXIING A C172 AT ZZZ THROUGH THE PARKING AREA. WHILE MOVING THROUGH THE AREA; I STRUCK A SELF SERVE FUEL PUMP WITH THE OUTBOARD EDGE OF THE R WINGTIP WHICH RESULTED IN DAMAGE TO THE LEADING EDGE; WINGTIP; AND SELF SVC FUEL PUMP. AFTER STARTING MY ACFT; I BEGAN TO MANEUVER THROUGH THE PARKING AREA IN ORDER TO AVOID ANOTHER ACFT WHICH WAS PARKED TO THE E OF MY ACFT ON THE N SIDE OF THE PARKING AREA. WHILE TURNING TO THE E; I BEGAN TO MOVE SLIGHTLY TO THE SOUTHERN EDGE OF THE TAXI AREA IN ORDER TO ALLOW ADEQUATE CLRNC FROM MY ACFT'S L WINGTIP; AND THE SPINNING PROP OF THE OTHER ACFT. I BELIEVED I HAD SUFFICIENTLY MANEUVERED TO AVOID THE OTHER ACFT'S PROP AND LEFT ENOUGH ROOM TO CLR THE FUEL PUMP. HOWEVER; I DID NOT ADEQUATELY JUDGE THE DISTANCE AND HT OF THE PUMP. I STRUCK THE PUMP MOVING W TO E. THE IMPACT CAUSED THE ACFT TO PIVOT AROUND THE PUMP. THE ACFT STOPPED IN A SOUTHERLY FACING POS. I IMMEDIATELY SHUT DOWN THE ENG; AND DETERMINED IF WE NEEDED TO EVAC THE ACFT. SINCE THERE WERE NO SIGNS OF FUEL LEAKAGE; I INSTRUCTED MY PAX TO STAY IN THE ACFT. THE PLT OF THE OTHER ACFT HAD SECURED HER ACFT AND WAS ALREADY MOVING TOWARDS MY ACFT. WE BOTH ASCERTAINED THE DAMAGE OF THE ACFT. I DECIDED THAT I SHOULD CALL FLT MAINT TO APPRISE THEM OF THE SITUATION. IT WAS DETERMINED; THROUGH DISCUSSIONS WITH MAINT; THAT THEY SHOULD FLY OUT AND INSPECT THE ACFT. IT WAS DETERMINED THAT THE IMPACT WITH THE PUMP DENTED THE OUTBOARD EDGE OF THE WING; IN ADDITION TO CRACKING THE LEADING EDGE OF THE WINGTIP. THE DECISION WAS MADE; BY THE DIRECTOR OF FLT MAINT; TO RECEIVE A FERRY PERMIT TO FLY THE ACFT BACK TO ZZZ1. THE OPERATOR OF THE ARPT WAS CONTACTED REGARDING THE DAMAGE TO THEIR SELF SVC PUMP. THE PUMP HAD SUFFERED SOME DAMAGE; AS IT WAS NOW LEANING TOWARDS THE E (DIRECTION OF IMPACT). A COUNTY EMPLOYEE INSPECTED THE PUMP AND NO SIGNS OF FUEL LEAKAGE WERE SEEN FROM THE PUMP AT THAT TIME. THE SELF SVC FUEL PUMP WAS LOCATED AT THE EDGE OF THE TXWY. WITH THE CESSNA'S WINGSPAN IT WOULD BE IMPOSSIBLE TO TAXI DOWN THE CTR OF THE TXWY WITHOUT STRIKING THE FUEL PUMP. THE FUEL PUMP'S HT WAS MEASURED TO BE 7 1/2 FT TALL.
