It depends on your exhaust and fuel tank. When I had the stock tank I mounted my pump were the rear muffler would go. The car had headers and little glasspacks so the exhaust never made it back so there was plenty of room next to the tank. Now I have a cell that is mounted in the spare tire well and the pump is in the left rear corner of the trunk or hatch floor on a bracket I made to lower it. Hope this helps.
