Volvo 740 Fuel Pump
Volvo 740 Fuel Pump is applied to supply gasoline from the tank to the carburetor or the fuel injector to ensure the engine fires up. This Volvo 740 comes in early carbureted editions having an engine-mounted mechanical pump that is driven by the camshaft lever to pump fuel at about 6 psi into the float bowl without overflow. Subsequent injection-equipped Volvo cars are fitted with a Volvo electric unit mounted within the tank, which is coupled with the sending unit of the gauge and capable of supplying 40 to 60 psi to the injectors. The two designs are similar in that they aim to produce a constant stream, but they are different in the place of operation, the operating pressure, and the method of activation, with an electric-powered design requiring voltage through a relay and the mechanical-powered design only turning on when the camshaft has turned. A failed component can be isolated when a 740 cranks but does not start, and an initial check of pump noise, a check of voltage level, followed by simple pressure or volume tests can be applied. Output ratings are expressed in gallons or liters per hour, and a simple rule of thumb is that the anticipated horsepower multiplied by 0.5 on a normal setup, or 0.75 on a boosted setup, divided by 6.2 determines the flow needed. In the event of additional volume demand, some high-flow mechanical pumps will require a pressure regulator to make the carb happy. In later Volvo 740 models, modern control units can pulse width modulate the Fuel Pump, which helps to cut back on heat and increase service life, making the old system remain efficient with the right Fuel Pump in place.

Volvo 740 Fuel Pump Parts and Q&A
- Q: How to remove and install the Fuel Pump and fuel system components on Volvo 740?A:For 2.3L and 2.8L 4-Cylinder and 6-Cylinder engines, respectively, to remove and install the fuel system components, you must first relieve the fuel system pressure and disconnect the negative battery cable. Safely hoist and support the vehicle, and then drain the Fuel Tank. Loosen the lock ring at the top of the fuel tank, and remove the sending unit with the transfer pump attached, making note of the direction of the float. Dismantle the transfer pump from the sending unit. Installation: For installation, attach the transfer pump to the sending unit, put the sending unit back in fuel tank and tighten the lock ring but don't overtighten. Reinstall the fuel tank, lower the vehicle, reconnect the negative battery cable, and start the engine to check whether there are any leaks. For 2.3L and 2.4L 5-Cylinder, and 2.9L 6-Cylinder engines, relieve the fuel system pressure and that disconnect the negative battery cable. Tilt the seat in the rear to the forward position and take the carpet over the trunk compartment out of the trunk over the right-hand wheel well panel, and disconnect the fuel pump electrical connections and note the color markings on the power hoses. Remove the quick-connect couplings on the fuel delivery and return hoses and remove the pump unit by unscrewing the retaining nut with the proper tool. Carefully lift the pump out without damaging connections by removing the rubber seal. For installation, place a new dry seal, lubricate and install the pump with the heater connection facing the right of the vehicle. Tighten the fuel pump retaining nut to the specified torque, apply petroleum jelly to the ends of the hoses, and connect the hoses to the pump making sure the quick-connectors are seated well. Reconnect the electrical connections, reinstall the panels and carpets, reconnect the negative battery cable and run the engine checking for leaks. For pressure testing, release the fuel pressure, and connect a fuel pressure gauge between the fuel line and distribution manifold or Schrader valve using a shop towel to catch any spilled fuel. On 700 and 900 Series vehicles, you can remove the seat belt reminder for easier testing. Start up the fuel pump by connecting a jumper lead between the terminals on the relay socket and check on fuel pump operation by listening at the fuel cap. Note the reading on the gauge, it should be about 43.5 psi then remove the jumper lead and relieve the fuel system pressure then take out the pressure gauge before putting the fuel pump relay back in.
