What happens here

The presenter begins disassembling the GPI pump unit by using an impact driver with a socket to remove the bolts securing the front cover plate. He carefully removes the plate, exposing the internal gears and a metal strainer. He shows how the strainer is heavily clogged with debris, preventing fuel flow. The gears are then removed, revealing more residue and highlighting the extent of the internal clogging.

Goal: This step focuses on taking apart the pump's main housing to access and inspect the internal gears and strainer for clogs.
