Electric Fuel Pumps?

Anyone......

I've heard that with the Carb Swap to a holley/weber that the fuel pump needs to be changed to a low pressure electric

If so, who sells them for the Sixes and what about the block off plate.

I was reading in The Falcon Performance book that the mechanical pumps can cause a flat spot on the cams. Since I'm replacing my cam in the next coupe of weeks I wondering if I should go with an electric pump instead?????
 
As far as a block-off plate, Autozone sells a chrome plate for the BBChevy (I think thats what the package says, its been a while). Its an exact match to the Ford small block, FE big block, and sixes. I used one on my 200 and another on a 352, no problem. Costs about $5. I bought the carter rotary pump that redline recommends 4-6psi, I'm still having problems. I'm going to try to jet my carb similar to stang200. Michael
 
For the block off plate follow 2manycars advice. I did the same thing. For the electric pump I used a holley blue pump and comes with a pressure regulator. I'm using a Holley 2300 2bbl 500cfm carb on an aussie head seems to work real well.

I highley recommend getting a pump that comes with a regulator and paying strict attention to the pressure requirements for whatever carb you have or end up getting. Intially I was running 4psi and the pump kept cutting out at the same place on my way to work. The carb calls for 5 to 7psi. I bumped up the pressure to 5-6 and haven't had a problem since. It's nice when you draing the float bowl to change jets or whatever you don't have to crank the engine over to fill it back up just turn on your key!!
 
does higher pressure = more gas used?

the ONLY reason I would go to a electric would be better regulation....
 
Yes but one comes with a regulator and the other doesn't. I believe the blue comes with the regulator and is the one I'm running.
 
still..blocking off 7-9 psi of pressure is quite a bit...slowing it down 3-4 is all i would do...at least thats the way i think after reading about elec. fuel pumps n stuff in other places.
 
Inliner....

Are you saying that the stock fuel pump is ok, or to go with the Carter Electric?????
 
a stock pump would be fine...if u use a pressure regulator be sure to install it as close to the carb as possible (read that from somewhere...i cant remember who said that)...that should keep the fuel from pulsating...usually the only time its necessary to upgrade to an electric pump is if u have a very large carb that requires a higher flow than the stock one can give or if u have nitrous or forced induction that requires a steady flow of fuel.
 
The stock pump will supply more fuel than you need in almost any N/A application - well over 200 HP, whether you have a 1bbl, a Holley, a Weber, or even a 4bbl. HP level determines fuel demand, not carb size.

There's no need to complicate the fuel system any more with an electric pump. Most in-line electric pumps also make noise while running... doesn't fit with the old car theme anyhow. The Holley red and blue pumps are nice but they are $$$ and can supply 4 - 5 times the volume of fuel you will need.

Higher pressure = more fuel in the engine on an EFI system. On a carb it doesn't change anything until you actually push the needle off the seat and overflow the carb bowl. That's about 4-5 psi on a Weber and 6-9 psi on a Holley, Carter, or Autolite.
 
thank you for clearing that up. I wont bid on anything and I will change ou the pump for a stock one.
