Fuel to carburetor trouble

I am getting fuel to the carburetor, but it is not going in. Is there anything that could obstruct the fuel flow inside the carb? Carb is a Holley 4barrel, engine is a 302 v8.

I don't think so, the sending unit is brand new (literally installed it today) and installed a new fuel pump a week ago.

I would agree with Steve. Can you check your fuel level in the front bowl? Is there a small window or a small screw to check your level? If the clog is lower, my next question is do you have a filter on your line somewhere?

Can you be more specific? Does it the start and die out, or does it just not start? Can you see fuel in the carb from the jets when it's running?

Hmmm...well if the floats are to low I dont think they'll let fuel in even with pressure..there's also the screen in the carb that if replaced with a paper filter is directional so if in backwards it won't flow..

I've never rebuilt a holley,but I have rebuilt old quadrajets and a couple edlebrocks...but with those there is a (sorry I don't know the name of it) hook that can pin down the float if not installed correctly..

Agree with steve..Floats are stuck in your fuel bowls, a quick check you can take the carb off, drain the fuel out, if any.. And turn the carb upside down, you should hear the floats move..

It cranks, there is fire going to the distributor, fuel to the carburetor, but no fuel gets to the jets. And I'll check if the float is stuck.

You could take your fuel line off and out it in a bottle and crank your motor to see if it's your carb or if it's your lines going to the carb

No, it's definitely not the fuel lines to the carb. I have a strong stream of gas pumping when the hose is detached.

Yes but by the previous owner, not sure if it was done correctly

Yeah well it seems like the only option is to take the carb apart and see what's going on.

I would (and probably will have to) do so, but it's just so damn complicated of a unit!

Yeah I know. I rebuilt mine but had to get a new one once I saw how worn out some parts were
