• Reinforced structure to limit cracking under heavy-duty operation

Installation is straightforward and achievable by most DIYers with basic tools. Follow a staged approach: relieve trapped air, separate the tank lid, swap the old manifold for the new one, then test under pump pressure for leaks.

• Step 1: Open the filter air bleed to release internal pressure
• Step 2: Remove clamps and lift the tank lid away from the base
• Step 3: Replace the old top manifold with the new unit and secure fittings
• Step 4: Restart the pump and inspect all joints for leaks
