The cause of the car’s jerking when engaging first gear or when the car is completely immobilized may be a broken gasoline pump, which will need to be replaced. Experts believe that replacing the fuel pump is easier than repairing it, despite the availability of spare parts kits.
Only the valves and cuffs are subject to replacement, because during operation they lose their elasticity, shrivel up and leak fuel.
The first reason why the fuel pump fails is poor-quality gasoline, in which air enters the intake, the gasoline pump begins to operate at high speeds and as a result does not cool down.
It is also worth changing the fuel pump when the rollers are worn, the impeller is faulty, and so on.
Replace the gasoline pump only after a complete diagnosis. If only the mesh is clogged, you should not replace the unit completely.
Signs of fuel pump failure
Some faults of the gasoline pump can be determined visually and by feeling. For example, if the engine does not start or extraneous noise occurs, if the engine runs irregularly or its power decreases while driving.
Recommendations for replacing the gasoline pump
When choosing a fuel pump, it is better to settle on a similar one to the broken one, and if you choose a unit of another brand, it is necessary to check the mounts.
You also need to pay attention to the branch pipe, which can be curved or straight. If the branch pipe has a different configuration, it will not allow you to fully secure the gasoline pump.
When replacing the fuel pump you will need certain tools, including a pump, as well as a technical agent WD-40 or similar liquid.
Work on replacing the gasoline pump should be done with gloves, away from flammable and explosive objects in a room with excellent ventilation.
When working, experts advise to mark the wires to facilitate then the installation of the unit.
Important: when dismantling the gas tank, you must be careful not to spoil the float on the sensor and prevent fuel from getting on it, otherwise the float will have to be replaced.
If you disconnect the hose and find that it has lost elasticity, you must cut it from the connection and replace it.
When the new gasoline pump is already installed, connect the battery and start the car for a short time. Then inspect all connections for leaks.
Car mechanics always insist on full observance of safety rules when replacing the gasoline pump, as this assembly is extremely explosive.
