1972 Mach 1 New carburetor

Hello all,
I just put on a new 1406 Edelbrock carburetor on and no gas is getting to the carb?

Tank is full and my gas gauge is reading empty when I turn the key...... what could it be?

Thank you

Blocked fuel line/hose, failed fuel pump, stick float needle in carb.

And welcome!

Amateur restorer. Well, sometimes I have been paid for it. But not right now.

The "tank says empty" bit is probably a bad sender in your fuel tank, but to be fair, the needle usually takes a bit of time to get where it's supposed to be.

22GT nailed the most likely reasons gas isn't getting in your carb!

How long did you crank it trying to get it to start (in seconds)?

I'll blame the Edelcrapp and suggest you trash it!

It doesn’t matter who manufactured the carb. If fuel isn’t being pumped to the carb, engine won’t run.

I like the CarterAFB and Edelbrock carbs. Very easy to tune.

I ran a 1406 years ago and never had issues with it. Once tuned, I don't believe I ever had to touch it again, until the day it was replaced. It may have been one of the most trouble free carbs I've ever installed. I'm with 22GT on this one.

The Edelbrock’s are good carbs. Empty reading may have something to do with it. I agree with 22GT

When you turn the key to the On or Run position the gauges should work. When you turn the key to Start the gauges don't work.


Did you pour a little gas directly into the carb venturis when trying to start? Carbs are shipped "dry" and you either have to prime them by cranking the engine for 30 seconds or by pouring gas directly into the carb and starting the engine.

Probably could be gummed up fuel lines, an electrical failure with the fuel pump(if you have an electric one), or maybe you need to clean the fuel filter.

Did it run prior to you installing the new carburetor? If so, the needle might be stuck. As others have said, pour some gas into the vents on each side of the carb to get it running.

Nothing worthwhile is ever quick, cheap or easy, those that can't do, complain

Did you remove the shipping plug prior to threading the fuel line into the carb?

Thought I'd ask. My sister called me and told me that the remote control to her TV didn't work. She replaced the batteries and the light comes on on the remote when presses the power button but the TV won't turn on. Turned out, the TV wasn't plugged in.
