Master 4033.038: tubo del carburante pompa-serbatoio

A fuel pipe pump-tank is a component used in oil-fired air heaters and burners. It connects the fuel supply from the storage tank to the oil pump, ensuring a steady and filtered flow of fuel to the combustion system. Parts of this type typically incorporate a filter element and a de-aerator to remove air bubbles from the oil, which helps maintain consistent pump pressure and prevents cavitation. The assembly usually includes connections for the suction line from the tank, a return line to the tank, and an outlet to the pump inlet. In some designs, the pump-tank may also house a valve for isolating the fuel supply during maintenance. When selecting a fuel pipe pump-tank, the key parameters are the pipe diameter and thread type to match the existing fuel line and pump inlet. The length of the pipe must allow proper routing without kinks or sharp bends that could restrict flow. Material compatibility with the fuel type—typically kerosene or gas oil—is essential; parts of this type are usually made from metal or reinforced synthetic materials. The filter micron rating should suit the nozzle size and pump tolerances. Some units include a sight glass to check for water or sediment, or a manual priming lever. During replacement, ensure the pump-tank is correctly oriented, as many models require the filter bowl to be at the bottom and the de-aerator vent at the top. Check all seals and O-rings for condition before installation. Tighten connections to the manufacturer’s specified torque to avoid leaks. After fitting, bleed air from the system following the pump’s procedure. Always verify that the replacement part has the same connection arrangement and flow direction as the original.
