What causes a fuel pump to leak at the bottom?
Fuel System Leaks 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.
What happens when both fuel pumps stop working?
When one or both fuel pumps (in the case of vehicles with two fuel pumps) stop working, fuel does not reach the injectors and the car will stall, just as if you ran out of gas. Electrical fuel pumps also use a relay and a fuse.
When to replace the seal on the fuel pump?
When this happens, oil can seep out around the fuel pump. If you notice a leak in this area, replace the seal as soon as possible, as detergents in the engine oil can cause further damage. There are several best practices to follow when replacing the fuel pump or the sealing gasket.
How can you tell if your fuel pump is dead?

How can I tell if my fuel tank is leaking?
It’s usually pretty easy to identify a fuel tank leaking; just crawl under the vehicle, and look for wet spots or stains on the fuel tank. Sometime a fuel tank will leak at the top; because moisture and debris get trapped on the top of the tank; and it rarely dries out; this causes the tank to rot and eventually leak.

How can I tell if my fuel pump is still working?
To perform this test, you should connect the test gauge to the metal output line using a spare piece of rubber fuel hose and a clamp. Once the connection is sealed, crank the engine over for 20 seconds. This will provide a full pressure reading, letting you know whether or not the pump is still in working order.
