Frequent Problems With Low-Pressure Mechanical Fuel Pumps

Old model cars using carburetor engines use low pressure mechanical pompe a essence solex (Solex fuel pump) to pump fuel in the fuel tank to motor. They’re mounted away from the tank, mainly on the face of the motor. With the arrival of fuel pump processes, many mechanical fuel pumps are replaced with electric ones, however, few older automobile owners are still keeping those pumps.


Low pressure mechanical fuel pumps tend to be less usable in comparison with electrical variants and incur common issues that result in drive ability problems. But on newer model automobiles using GDI equipped motors, they’re making a recovery. There’s an electrical fuel pump from the cylinder delivering fuel into a high pressure motor powered mechanical fuel pump.

In the following guide, we’ll discuss just about the typical problems with reduced pressure mechanical pompe a essence solex utilized in carburetor engines alongside the techniques to spot and solve them.

Vapor lock:Vapor lock happens whenever the fluid fuel at the shipping system transforms to gaseous type and blocks the passage of this fuel. Since it’s situated in the motor compartment, the higher motor heat over the side of the cylinder comes with the fuel at the fuel lines resulting in vaporization.

Because of steam lock, the performance of the pompe a essence solex becomes disturbed. It causes reduction in feed pressure, which leads to loss of electricity transmission to the motor or total stalling of vehicle. Frequent indications of steam lock aren’t any very low fuel pressure, dry carburetor air conditioner without a accelerator pump release, stalling, difficult beginning and very low power.

Fuel foaming:This happens when chilly fuel enters a sexy carburetor resulting in a run of brief jerks on acceleration and ultimately leads to search engine. The average signals are dark smoke emitted in the exhaust pipe, moist carburetor air conditioner and beginning of motor following a very long wide open throttle crank.
