While looking for a good place to mount the pump, i did give it some thought about mounting it in the trunk, but it would have been above the bottom of the cell by a good margin, that and the fact if it ever developed a leak it could be a safety issue. A leak inside the trunk could become a quit large bomb with a mix of 93 and 113 race fuel. Unless i have an issue with the pump where its at, its stayin put.
