Mechanical 2-Hole (45 mm Spacing) Diaphragm Fuel Lift Pump for Same & Lamborghini Tractors - Part Number: 38019115

The mechanical diaphragm diesel fuel lift pump (feed pump) (part number 38019115, original SDF OEM references 0.003.8319.6/10, 0.003.8319.6, 2.4519.200.0, 2.4519.190.0, 2.4519.180.0, 2.4519.160.0, 2.4519.150.0) is a camshaft-driven low-pressure fuel supply unit engineered to deliver steady, bubble-free diesel flow from the tank to the main fuel injection pump. Built with a 2-hole mounting flange featuring exact 45 mm center-to-center hole spacing, it is driven by the engine camshaft eccentric lobe and features an integrated manual priming hand lever to facilitate fast air bleeding during routine servicing. Built to factory standards for 2, 3, 4, and 6-cylinder SDF powertrains, it delivers reliable operation across classic wheeled and crawler tractors from Same (Delfino, Falcon, Condor, Minitauro, Sirenetta, Aurora, Ranger, Corsaro, Saturno, Centurion, Leopard, Panther, Drago, Buffalo, Solar, Tiger, Vigneron, Taurus C) and Lamborghini (Series 300, 500, 600, C-Series crawlers, R-Series 200–1000).

Key Features & Engineering Advantages

• Factory-Calibrated 2-Hole Flange (45 mm Spacing): Precision-machined 2-stud mounting pattern designed to match Same and Lamborghini engine block ports, ensuring flat alignment and oil-tight sealing.
• Heavy-Duty Reinforced Diaphragm: High-grade synthetic elastomer matrix resists chemical degradation from modern diesel fuels and biodiesel blends (EN 590 / FAME), eliminating fuel leakage into engine crankcase oil.
• Integrated Hand Priming Lever: Simplifies field and workshop servicing by allowing manual air bleeding from the supply lines and quick refilling of diesel filter bowls without excessive starter motor cranking.
• Precision Internal Non-Return Valves: Calibrated spring-loaded check valves maintain supply line prime when the engine is turned off, preventing drain-back to the tank and ensuring instant cold starts.
• Comprehensive SDF Engine Application: Drop-in compatibility across 2, 3, 4, and 6-cylinder diesel engines from Same (105.3, 105.4, 916.2, 916.3, 916.4, 982, 983, 984, 986, 1000.4, 1000.6, 1053) and Lamborghini (986).

Installation Advice & Workshop Notes: Thoroughly clean and scrape away all remnants of the old gasket and oil deposits from the engine block port. Manually rotate the engine flywheel until the camshaft drive lobe is positioned at its base circle (lowest lift point), allowing the rocker arm to slide into place without high spring preload against the two 45 mm spaced studs. Always install a new gasket of correct factory thickness to ensure proper pump stroke and prevent oil weeping; tighten the two retaining nuts evenly to manufacturer torque specifications. Once the fuel suction and delivery lines are reconnected, pump the manual priming lever until bubble-free diesel flows from the fuel filter air vent screws.
