Adapter part for:

This is sold as a single item.
Light Duty Diesel Injection Kit includes one 5/16″ ID fuel hose 6″ length in addition to many other adapters.
FOR DIESEL SERVICE:
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.
