Mechanical Diaphragm Fuel Lift Feed Pump for Deutz-Fahr, Lamborghini & Same Tractors - Part Number: 38004706

The mechanical diaphragm diesel fuel lift feed pump (part number 38004706, original SDF OEM references 2.4519.330.0/50, 24519330050) is a camshaft-driven low-pressure fuel delivery component engineered to ensure steady, bubble-free fuel transfer from the fuel tank to the main diesel filtration assembly and injection pump. Built to OEM specifications for the broad family of SDF 1000 series diesel engines (3, 4, and 6-cylinder naturally aspirated and turbocharged configurations), it features a heavy-duty reinforced diaphragm resistant to fuel degradation and includes an integrated manual priming hand lever to simplify circuit air bleeding during routine servicing. It provides direct plug-and-play fitment across wheeled, orchard/vineyard, and crawler tractor ranges from Deutz-Fahr (AgroClimber, AgroCompact, Agrofarm, Agrolux, Agromaxx, Agroplus, Agrotrac), Lamborghini (C, CF, Crono, CV, Grand Prix, Plus, R2, R3, R4, R5, Rekord, RF, RS, RV), and Same (Argon, Argon³, Dorado, Dorado³, Explorer, Explorer³, Frutteto II, Frutteto³, Krypton, Krypton³, Laser, Laser³, Silver, Tiger).

Key Features & Engineering Advantages

• SDF Group OEM Mechanical Tolerances: Manufactured to exacting original equipment parameters, ensuring positive alignment of the internal rocker arm with the camshaft drive lobe and eliminating stress on the engine block mounting port.
• Reinforced Multi-Layer Diaphragm: High-grade synthetic elastomer matrix built to withstand standard agricultural diesel and modern biodiesel blends (EN 590 / FAME), preventing fuel dilution into the engine crankcase oil.
• Integrated Hand Priming Lever: Facilitates rapid manual bleeding of air bubbles from the fuel lines and pre-filling of fuel filter cartridges without placing strain on the starter motor and battery.
• Factory-Calibrated Internal Check Valves: Precision spring-loaded check valves prevent fuel drain-back to the tank when the engine is turned off, ensuring smooth, instant cold-weather starts.
• Broad Fleet Compatibility: Universal replacement for an extensive range of wheeled, narrow-track orchard, and crawler machines across Same, Lamborghini, and Deutz-Fahr agricultural fleets.

Installation Advice & Workshop Notes: Before installation, scrape off all remnants of the old gasket and thoroughly clean the engine block mounting port. Rotate the crankshaft so the driving camshaft eccentric lobe sits at its lowest lift position, allowing the pump rocker arm to slide into place without high mechanical preload. Always install a new mounting gasket of the specified factory thickness; never use liquid silicone gasket maker as excess sealant can alter rocker standoff distance or block oil drainage ports. Tighten mounting fasteners evenly in an alternating sequence to manufacturer torque specs. Once fuel lines are reconnected with new sealing washers, operate the manual priming lever until bubble-free fuel flows from the fuel filter bleed screws.
