Im wondering if the fuelpump for my car is in the undercarriage of the car or weather it is in the tank in the top somewhere. Someone please help?

Interestingly the car's fuel cell as routed by factory is only a few inches away from the exhaust.

Pull up rear seat, cell is revealed, and after a few covers and seal rings, you have reached Octane heaven.

Dahlback sells proprietary replacement for fuel pump and fuel regulator. Built by Bosch.
