What happens here
After installing the new fuel filters, ensure the fuel shut-off valve is open. To bleed the system and remove any trapped air, operate the primer pump lever on the fuel pump. Continue pumping until you see a steady stream of fuel (without air bubbles) emerging from the banjo bolt at the top of the secondary fuel filter. Tighten the banjo bolt once fuel appears, then pump until fuel also emerges from the top bolt of the primary filter. Ensure there are no fuel leaks from any of the newly installed filters. The presenter emphasizes tightening bolts only until fuel leakage stops, rather than overtightening, to prevent damage.
Goal: Remove air from the fuel system after filter changes
