Why does my golf cart smell like gasoline?
Deterioration. Rubber vacuum and fuel lines will eventually deteriorate. This issue is far more common in older and pre-owned golf carts and ATVs that haven't been given regular tune-ups. If you're having problems with the fuel not making it to the carburetor, check the lines very closely. Even if you can't see deterioration, a telltale gasoline smell will let you know that they may have begun to fall apart. Remember: a pin hole or other small area of damage may not be visible, so make sure to check for the fuel smell.
How does a fuel pump work?
The power created by the pulse is transmitted through a vacuum line from the lower end of the engine through the fuel pump or pumps.

If you take a look at your fuel pump, you will see that the Fuel In and Fuel Out areas are marked ...
Why does my fuel pump stop working?
Over time, the fuel pump's ability to function will fade and eventually it will stop working entirely.

The diaphragms are the thin sheet of plastic which separate the pieces of the fuel pump.
Why is my car's engine not producing power?
Performance problems could also be caused by issues involving the crankcase or engine. A leaky crankcase or damaged engine cannot produce effective power. You'll want to take a look for signs of an oil leak, a bad crankshaft seal, or issues with the case gasket.
What is crankcase pressure?
While the more generally recognized term "compression" refers to the pressure limits at the top end of the engine, crankcase pressure actually refers to the pressure present at the bottom end, below the piston. While the pistons move up and down, the crankcase pressure will vary; we call this a "pulse.".
Can gasoline build up on golf cart fuel pump?
Debris buildup. Gasoline isn't exactly the cleanest fuel source there is, and even high-quality fuel may contain dirt, debris, or other contaminants. Over time, this debris can build up and become lodged inside the fuel pump. An inline fuel filter will take care of most of this, but some may still build up, and in order to remove the debris you'll need to remove the pump itself from the golf cart and disassemble it .
Issue 1
Rubber fuel and vacuum lines naturally deteriorate with time. If you are having issues with a lack of fuel getting to the carburetor, be sure to check the lines closely. With rotted fuel lines, you will either smell a gas odor or possibly see signs of leaking gas.
Issue 2
Since golf cart fuel pumps are based on a vacuum created by crankcase pressure, if there is any type of leak in the crankcase or lower end of your engine, you may experience fuel issues. An effective output cannot be produced from an engine with a leaky crankcase. Check for any outward signs of an oil leak.
Issue 3
For the price of fuel these days, it should be the cleanest substance on earth. The truth is that it is not and often contains contaminants straight from the pump. This debris can get sucked out of the fuel tank and end up lodged in the pump.
Issue 4
Related to issue 3, the diaphragms inside the pump are very thin and fragile. They occasionally break or develop tears, which would cause the pump not to function. It would need to be removed as describe above, disassembled and the diaphragms replaced with a rebuild kit.
