So... inside the tank you think???

Ah haha but I thought it would just keep going. Also putting air pressure to it does nothing and makes the pump continuously build which made me originally think it was a blockage.

Webers are very sensitive to too much fuel pressure. 2.5 to 3 PSI is about it. Is this the electric pump? what's the pressure rating?? Try the stock pump, they are just over 3.

 

You may need to clean the fuel inlet needle. There may be dirt preventing it closing.

It's on the stock pump. Fuel inlet? From the tank or carb?

The carb has a float that rises and shuts off fuel entering the carb.

Do Weber 38's have that? I'm assuming I'm have take the top part of the carb off? It's a new carb I'm unsure why it's even having this issue 😭

Not a Weber carburetor expert, but probably. Replace the fuel filter first unless new.

 

If you can't find anything you may have to put a fuel pressure regulator in line.

So I put a fuel pressure regulator with the lowest possible setting, in addition to the Jeep c7 fuel filter that sends a return back to the tank, and IT'S flooding it, on stock pump. I'm starting to think it's just the carb, even tho it's brand new.
