How do you adjust the pressure on a Suntec oil pump?

There is a pressure adjustment screw on the upper side facing away from the boiler. There’s a ‘big ole nut’ with a screw adjustment in the center. You can attach the gauge to the port on the top of the pump.

How does SU fuel pump work?

SU Fuel Pump Operation. The SU fuel pump is an impulse type of pump. That is, when power is supplied to the pump, current flows through the points and the solenoid coil. This movement of the diaphragm develops a vacuum in the pump body, which pulls fuel from the tank, through a check valve and into the body.

What is Su electrical fuel pump?

S. U. Electrical Fuel Pump: Working of Electric Fuel Pump: It consists of a diaphragm which is operated electrically. By turning on the ignition switch, the solenoid winding generates magnetic flux, which pulls the armature and the diaphragm moves up.

What is an SU fuel pump?

As you all know, SU stands for Skinners Union and was the brainchild of George and Carl Skinner. In addition to building the well known and much loved SU carburetors, they also went into the fuel pump business. They started in the 1932/33 time with the L, low pressure pumps.

How do you adjust the pressure on a oil pump?

The oil-pressure regulator on the fuel pump is generally factory-set to give nozzle oil pressures of 100 psig….Adjusting Fuel Pump Pressure

1. Turn the adjusting screw clockwise to increase pressure.
2. Turn the adjusting screw counterclockwise to decrease pressure.
3. Never exceed the pressures indicated in Table 1-2.

Where is the fuel pump located on older cars?

How to check the fuel pump

1. Make sure the vehicle is off and safely parked on a level surface.
2. On most vehicles, the fuel pump is located in the fuel tank.
3. Next, you will need an assistant to turn the key to the “on” position while you listen near the gas tank opening.

Where are SU carburetors made?

North London
Company Limited. S. U. Company Limited — Skinner-Union — was incorporated in August 1910 to acquire Herbert’s carburettor inventions, and it began manufacture of the carburettors in a factory at Prince of Wales Road, Kentish Town, in North London.

What are the two types of electric fuel pump?

There are two types of Electric fuel pumps: Electric In-Tank Fuel Pumps and Electric External Fuel Pumps. Electric In-Tank Fuel Pumps are more common than the Electric External Fuel Pumps.

How do you change a fuel pump on a MGB?

First task is to remove the near-side rear wheel to gain easier access to the pump. Cover the exposed spline or hub to avoid getting greasy. Next, disconnect the unions and breather pipe, loosen the pump bracket (normally two bolts) and remove the pump, being careful with the electrical connections.

Where is the nozzle outlet on a Suntec pump?

SUNTEC pump identification 2.1 Choice of SUNTEC pump configuration (shaft rotation and nozzle outlet) Notes : This codification is valid for any SUNTEC pump except A2L, AUV and ATUV pumps. For A2L, the configuration is determined by the shaft rotation and the side pressure gauge port location.

How big is a Suntec fuel oil vacuum?
