Why is there no fuel going to my carburetor?

No fuel at your carburetor can be caused by many things. It could be a simple issue like a fuel filter plugged so tight that no fuel can pass through. Another logical cause could be the fuel pump. A hole in the fuel line on the tank side could also cause the fuel pump to suck air instead of fuel from the fuel tank.

What would cause a new fuel pump to not work?

If the fuel pump is not coming on, and the fuse and relay are good, then it may be possible that there is a problem with the pump or the fuel pump circuit. If it is not then there may be some sort of wiring issue before the fuel pump relay, perhaps a wiring issue or other problem with the ignition switch.

Does changing the fuel pump make a difference?

No. Larger injectors and a modified fuel map are the first changes along with a wide band O2 sensor. If you are worried about needing a larger fuel pump, put a pressure gauge on the fuel delivery rail.

What should I do if my fuel pump isn’t working?

Make sure you have fuel all the way up to the fuel pump. Then make sure all your lines are tight. Leave line disconnected from the carb till you get fuel to the carburetor. You might try using an auxiliary fuel tank and a piece of hose to verify the pump is working correctly and you don’t have an issue with the new tank.
