What happens here

With the new fuel pump and sending unit installed in the tank, it's time to reinstall the tank into the vehicle. This may require two people due to the weight and awkward size of the tank. Carefully lift the tank and slide its front edge past the cross-member, then raise it into position. Use ratchet straps or similar sturdy straps to temporarily secure the tank. Connect the necessary fuel lines and wiring harnesses. For the fuel lines, install the new fittings (e.g., DeatschWerks fittings) that convert the factory-style push-lock connections to AN lines. These AN lines will run forward to the engine bay, connecting to the fuel rail. The fuel system includes a feed line and a return line. The factory intake manifold might have a built-in boost-referenced regulator, eliminating the immediate need for an aftermarket regulator. However, an aftermarket regulator and associated dash-10 to dash-8 O-ring base fitting may be used if the factory setup is insufficient or if a different intake manifold is used.

Goal: Secure the upgraded fuel tank and establish all fuel and electrical connections.
