for some reason my carb is just dumping fuel into the carb looks like it it coming from the secondaries as soon as turn the fuel pump on. I took it apart it was clean and the floats are not stuck, I out it back and seemed to be fine then later on I tried it again and it was pouring fuel into the carb, what do you think is the cause it seems to be more fuel closer to where the fuel line is connected to the carb. i dont know what else to look for.

I don't believe these can take much fuel presure what are you at?

6 psi is about the limit

Yep, as said fuel pressure needs to be low... I run 4.5 to 5.. all it needs

I dont have a guage but I am using one of those carter elec pumps thats suppost to max out at 6lbs, do you think it can still be a bad pump?
I have another pump I will try that.

I seriously doubt it the fuel pump, 6 psi isn't that much, if that is what you have. Did you check for floats full of gas? I have had that happen several times in the 20 years I've had my 1407 carb. Also, did you check the float level and drop? Did you inspect the seats and especially the tip of the needle for burrs/jun?

Just because the pump is rated at 6psi doesnt mean its not putting out more. Put a gauge on it.

I agree use a gauge. They will do this with to much pressure. I have had this with gm, ford and my 408, all with mechanical pumps. Some pumps work some do not.

had the same problem, same carb, same pump. a gauge and a regulator solved it.

just wanted to say thanks it was the pump not the carb
I tried another pump and it works fine
I ordered a fuel pressure gauge
