Electric fuel pump

Hello all.
I have a 30 CCPU and it has developed a fuel leak at the tank. I bought a good used tank, but it needs paint, etc. so it is not ready yet. I would still like to use the truck for a few upcoming events. I have a small fuel cell lying around from my old racing days. My question is...

Has anyone used a 6 volt pump, such as the Carter model sold through MAC's?

If so, does that thing hum bad? Some external electric pumps are as loud as the running engine...

Do I need an adjustable regulator?, or does the 2-4 lbs. work fine.

The engine is stock. Thank you.
 
Don't know what MAC's looks like but we're using a 6 volt Carter style pump on a '36 car to complement a vacuum fuel pump. Ours humms a bit but we only use it to pass fuel to the motor after the car sits awhile. They do need a good ground, and we have an in- line filter to keep sediment out of the pump along with a small pressure regulator for about 3# pressure because some pumps produce a lot more flow than that. The cylindrical types ( Airtex) according to many blogs are supposedly prone to failure,but have no experience with those.
 
I agree with Brent, and I bought two 12 volt Holley rotary pumps and run them on my 6 volt battery in my 1950 Studebaker. In fact I also put a resistor inline to reduce the voltage to 3 volts, and that's perfect. It has lowered the pressure and volume and will make the pump last much longer while also using less electricity. I can't hear it run either.

Unfortunately you have made the purchase but actually, the way to do it is to purchase a 12v pump locally and run it on 6 volts. That way you don't need a pressure regulator.

My brother did this same thing on his T.
 
I bought the Airtex 6 volt pump with a Holley pressure regulator and a gauge. I will run it hidden along the frame rails from a spun aluminum fuel cell mounted in the bed. It has a nice, clean look. I will plumb it to the line behind the sediment bowl so it looks factory. If the bowl doesn't seal well, then I guess I will have to run it direct to the Zenith. As soon as I receive all of the parts, and start the project, I will post the pics. Thank you everyone for your advice.
 
This is the pump I have mounted between the frame edges below the weber carb.

Can you tell me what kind of fuel pump are you referring to? Is it a low pressure pump? Thanks
 
I'm not Brent, but my 12 volt Holley would put out 15 PSI and a lot of flow, even on 6 volts. I used a resistor to drop the pump voltage to 3 volts and it now puts out less than 2 PSI and enough flow to run my 1950 Studebaker.
