That's where my fuel pump is on both my Darts - back-up pump to prime the engine, and when racing. This is also where the torque plates go - a great addition, so if you plan to install them in the future you might consider that. On my car that doesn't have torques plates I fashioned a similar thin sheet metal cover that is screwed to the subframe members to protect the fuel pump and hoses from road debris.
