Forklift Hand Oil Pump MIT F18B S4S – Manual Fuel Primer

Forklift Hand Oil Pump MIT F18B / S4S — Manual Fuel Primer Hand Pump for Forklift Diesel Engine

This forklift hand oil pump model MIT F18B/S4S (LFT number LF07-M001G) is a Kingstream OEM manual fuel primer pump for Mitsubishi S4S, F18B, and other diesel engines in forklift trucks and industrial equipment. The hand oil pump is the manual priming device mounted on the fuel injection pump or fuel filter housing — it is operated by hand to manually pump diesel fuel through the fuel system after filter changes, engine service, or when the fuel system has lost prime. This eliminates the need to crank the engine excessively to bleed air from the fuel lines. 0.5kg with 20×15×15cm neutral export box packaging. MOQ 1 piece. Kingstream OEM for Mitsubishi engine forklift fleet fuel system maintenance.

INSTALLATION: Step 1 — Identify the mounting location on the fuel filter housing or injection pump. Step 2 — Remove the old hand pump by unscrewing the threaded collar or removing mounting bolts. Step 3 — Clean the mounting surface and replace any O-ring or gasket. Step 4 — Install the new hand pump and tighten securely. Step 5 — Operate the pump handle to verify smooth pumping action and fuel flow. Step 6 — Prime the fuel system by pumping until resistance is felt and fuel flows freely without air bubbles at the bleed screw. For Mitsubishi S4S/F18B forklift fuel system maintenance, contact us. Kingstream OEM.

SYMPTOMS OF FAILURE: Unable to prime the fuel system, fuel leaks from the pump body, pump handle feels loose or does not build pressure, and air continually entering the fuel system. Kingstream OEM.
