Huge advantage to having the pump more accessible with the relocation kit, as opposed to on top of the starter and subject to all that heat and vibration.

Do you still need to bleed the system at the inlet of the injection pump when you do the filter change?

I just drain filter housing, remove old filter, install new filter. Fill filter housing with fresh fuel, drop filter. Cycle the key switch 3 time (leaving the key on without starting for about 30 seconds each time) And my trucks starts right up with no priming issues. Hope this helps
