Electric and Belt Drive Fuel Pumps

Lucas Electric Pumps

Lucas Electric fuel / petrol pumps are used to run lower power engines like the Triumph PI cars
in the UK, and for starting race engines. After a race engine starts it relies on a belt drive fuel pump
to provide the 110 psi pressure and volume needed for high power engines. The belt drive pump
is the exact same pump as the Triumph, only fitted with a belt drive pulley instead of an electric motor.

These pumps come in two versions, a "thin" 1/4 inch center section, and a "thick" 3/8 inch center section.

Important Note.

• Bosch Fuel Pumps have their flow rates defined in N-Heptane as part of their engineering specification. N-Heptane is a pure
chemical and does not have the same viscosity and density as standard petrol. Hence the N-Heptane flow rate figures stated
should be used as a general guide for comparison purposes only.
• Bosch Fuel Pumps are designed for use with standard grade petrol. Subject to statutory warranties, Bosch does not warrant
the performance characteristics or specifications of these fuel pumps if they are used with Alcohol or Ethanol based fuels or
fuel additives that are corrosive.

From what I am told, the  0 580 254 044 and the B 261 205 413 are the same pump,
Bosch tests the "044" to qualify it to be called a "413"  (see flow chart)
