Mechanical 4-Hole Diaphragm Fuel Lift Pump for Same, Lamborghini & Hürlimann Tractors - Part Number: 38019305

The mechanical diaphragm diesel fuel lift pump (feed pump) (part number 38019305, original SDF OEM references 2.4519.230.0/10, 2.4519.290.0, 2.4519.220.0, 2.4519.230.0) is a heavy-duty camshaft-driven low-pressure fuel supply component engineered to provide reliable, continuous fuel delivery from the fuel tank to the primary diesel injection pump. Built with a 4-hole mounting flange featuring precise center-to-center hole spacing (vertical hole spacing = 25 mm, horizontal hole spacing = 45 mm), it incorporates an integrated manual priming lever to purge air from the fuel system after filter replacements. Designed to original equipment standards for SDF Group powertrains (Same, Deutz-Fahr, Lamborghini, Hürlimann), it delivers direct bolt-on fitment across classic and modern wheeled and crawler tractors from Same (Laser, Centauro, Corsaro, Buffalo, Drago, Saturno, Taurus, Minitaurus), Lamborghini (Series 1000, C-Series crawlers, R-Series 600–1000), and Hürlimann (H-Series 351–6170).

Key Features & Engineering Advantages

• Factory-Calibrated 4-Hole Flange (25 x 45 mm): Matches SDF engine block mountings precisely, guaranteeing an oil-tight seal and positive alignment with the camshaft drive lobe.
• Heavy-Duty Reinforced Diaphragm: High-grade synthetic elastomer matrix withstands modern diesel formulations, sulfur variants, and biodiesel blends (FAME), preventing fuel leakage into the engine crankcase.
• Integrated Manual Priming Lever: Simplifies workshop routine servicing by allowing rapid manual purging of entrapped air and quick filling of fuel filter bowls without prolonged starter cranking.
• Precision Internal Non-Return Valves: Spring-loaded check valves maintain supply line pressure and prevent drain-back to the tank when the tractor is shut down, ensuring rapid cold-weather starting.
• Extensive Multi-Brand Powertrain Coverage: Universal fitment for SDF Group engines across Same (916.3, 916.4, 1000.6, 1054, 105.4, 105.5), Lamborghini (984, 986), and Deutz (H1106).

Installation Advice & Workshop Notes: Thoroughly clean and degrease the engine block mounting surface, removing all traces of the old gasket. Ensure the camshaft driving eccentric lobe is turned to its low point (rotate the crankshaft manually if needed) so the pump rocker arm can be installed without excessive preload tension against the studs. Always install a new gasket of correct factory thickness to preserve the specified rocker stroke; tighten the four mounting bolts (25 x 45 mm spacing) in a crisscross sequence. Connect the fuel suction and delivery lines, then pump the manual priming lever until bubble-free fuel flows from the fuel filter bleed screws.
