How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Common causes of fuel pump leaks from the weep hole are either high inlet fuel line restriction or high fuel pump drain line restriction.
Causes of Fuel Pump Leaks

The pump is connected to a metal tube and a rubber hose. Over time, the metal tube can start to rust and leak, and the rubber hose may also deteriorate. Fuel leaks may also be caused by damage to the vehicle either from harsh driving conditions, accidents, or time and use.

The fuel pump can experience internal leakage or loss of pumping efficiency causing slower pressure rise in the fuel rail.
An engine that misfires, runs lean, hesitates, or stalls could have a leaking diaphragm or valve within the fuel pump. Both of these problems cause the fuel pressure to drop, starving the carburetor of gasoline and creating the above symptoms.
Most mechanical fuel pumps have a weep hole on the bottom of the unit. When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction. This is one of the more common fuel pump problems found in classic cars that are between 30 and 60 years old.
With a fuel leak, a car is never safe to drive.

In addition, leaks in the fuel system are a common cause of car fires. Since gas is extremely combustible, it is possible that it may spark a fire, either inside the car or elsewhere, if it leaks. Therefore, fixing the leak as soon as possible is highly recommended.

High fuel pressure results in a rich air-fuel ratio because the increase in pressure forces more fuel through the injectors than required producing increased emissions (HC`s) and black sooty exhaust. These excessive hydrocarbons overheat and damage the catalytic converter.

Coolant leaks from the water pump are common and a clear sign that it`s time to replace the pump. The coolant is stored inside the water pump using a series of gaskets and seals. Once these parts wear out, loosen, or crack, you`ll end up with radiator fluid leaking out of the front of your car toward the center.
The coolant system and the fuel system are unrelated. If one is malfunctioning it will not have an effect on the other one.

This can grow into a more serious issue when the water pump casing develops a leak. If you ignore this the engine will overheat due to bad coolant flow causing further damage to the engine block and head, eventually wrecking the engine.
