Rover V8 Fuel Pump - Carb Engines
Most early non power steering V8 engines have a mechanical fuel pump bolted to the timing cover and driven by a lobe on the camshaft spacer. One exception to this is the MGB GT V8, which in common with other MGBs has an electric pump at the rear of the car. Power steering equipped cars usually have an electric fuel pump (due to the location of the p.a.s. pump where the fuel pump had previously been).
Rover SD1 and TR8 carb vehicles both have in-tank fuel pumps, which deliver approximately 4.5psi pressure (ie. usually sufficient for a Holley or Edelbrock carb but inadequate for efi).
Rover SD1 EFi vehicles have a high pressure fuel pump (delivering around 40psi), mounted very close to, but outside, the base of the fuel tank. Early power steering equipped Range Rover Classics have an electric pump in the engine bay. From 1986, the carb and EFi fuel pumps are both fitted inside the fuel tank. However, the two types are not interchangeable, as the EFi pump is a high pressure type not suitable for carb vehicles.
Up to approximately 1991, the in-tank fuel pump is separate from the fuel level sender. From 1991 onwards, the pump and sender unit are combined.
Defender and Discovery Series 1 V8 models follow the same fuel pump evolution; the Range Rover Series 2 and Discovery Series 2 however have always used a combined pump and sender unit, mounted in the tank. We also stock a Facet electric fuel pump, designed to fit in the engine bay. Suitable as a replacement for any carb vehicle, including Edelbrock or Holley-equipped, it delivers 4-5psi pressure. It is therefore not suitable for EFi. See below for listing.
