Fuel priming on 71T first startup
 

Hi All, I'm about to start up my engine for the first time. I have Wayne's book and are familiar with the important steps before startup.

My question is, due to the fact that I have a new fuel tank, fuel hoses, filter etc the system is completely empty. I have restored the carbs as well. The fuel pump is a restored original.

Should I prime the fuel system first before I turn the starter. I assume the fuel pump kicks in on the first or second step on the ignition and then fills up the carburetor bowls. Correct?

Is there a better way to do this other than to pour some fuel into the throats and turn on the starter?

Appreciate all input.

All the best,

Only thing I would suggest is disconnecting the fuel lines at the carburetors so you can clear the lines while measuring fuel delivery. Turn on the key and watch for debris and flow.
500-700cc per minute ?

Thanks for your input Henry. I have had the pump rebuilt and tested so I know it is up to spec.

Key on should allow the fuel pump to run (you'll hear it). Assuming the pump is doing its thing, 10-20 seconds should be plenty to get fuel to the carbs.

Especially if you've had the fuel system apart, I'd do the above, and stop and inspect for leaks before starting the engine.

Thanks, that's what I was thinking.

It's really important to have fuel in the float bowls before you attempt to fire it up, a single backfire can crush the floats :-( Dont ask how i know

Once the fuel pump is running watch the carbs to ensure the floats work/don’t stick. Look for any fuel seepage or overflow. If all is well then attempt to start.

Good practice anytime you let the car sit for weeks between drives as well.

Thanks for your input. I have restored the carbs and set the float level. I will check the float bowls before I attempt the first start.
