Service Instructions


① Depressurize tool before removing fill cap.

② Fill tool with diesel injection cleaner.

③ Attach required adapters to vehicle diesel fuel lines.

④ Connect BLACK service hose (pressure gauge side) to the “Feed” line adapter and the RED service hose (pressure regulator side) to the “Return” line adapter. If required, disengage or loop diesel fuel lift pumps.

⑤ NON-PRESSURIZED SERVICE: If diesel fuel pressure is not required (no lift pump or connected behind the lift pump), open the tool fill cap slightly during service to avoid creating vacuum in the tool.

⑥ PRESSURIZED SERVICE: If pressure is required (replaces lift pump pressure), set tool pressure to the required fuel pressure level for that engine.

⑦ Run engine at idle until cleaner drops to “0—–0” level, then shut off.

⑧ Remove diesel fuel adapters, service tool, reconnect fuel lines, and pump.

(must use specific engine job aids for all details):

① Remove the tool fill cap and fill tool with water-based cleaner.

② Install the exhaust and intake adapters.

③ Attach the adapters to the Affinity EG service manifold and connect the manifold to the Affinity EG Diesel Induction & EGR Service Tool.

④ Start the engine and bring to normal operating temperature.

⑤ Set tool pressure to 50-60 psi & open the Exhaust valve to run 32 oz of cleaner through the exhaust system.

⑥ Rotate the manifold valve to the exhaust setting and increase engine to 1500 RPM.  Run the remaining 32 oz through the induction system.

⑦ Run the engine 10 minutes after the cleaner is consumed and remove adapters.  Drive vehicle to clear/remove any loosened soot.

⑧ Run DPF regeneration cycle if required
