Hi friend: -a conventional "silent" mechanical/fuel-pump is definitely the safest for normal motoring (stops pumping when motor quits, such as during an accident); ---yet it also makes good sense to include an electric/fuel-pump preferably situated near the gas-tank as they typically push better than pull (you can get a rotary-pump such as the Carter "whirrrrrrrr", or you can use the linear-pump unit such as an AutoPulse solenoid type "click-click-click-click"). Thus with the electric-pump connected through a load-relay to a momentary-switch(or button) on your dash, --you can thereby readily 'prime' the carburetor for a few seconds, before cranking the engine (which is especially handy if your car is only driven occassionally). Note that the mechanical/fuel-pump will pull fuel right through in-line with the electric/fuel-pump...
Hope this helps... ~Robair vH sandiego

Why bother with all the hassle of an electric fuel pump (plumbing, wiring, relays, switches, safety shutoff, noise, etc.)? A replacement stock pump is about $30.00 and takes an hour to replace.

One last note. Your using an Edlebrock carb. Without a fuel regulator, the electric pump will blow the needles off the seats in the carb.

Your Edelbrock carb should have no more than about 7.5 PSI of fuel If I remember correctly.

Check into a carter Hi FLow pump. It has high flow and low pressure. Works great with the carb. BEWARE of the autozone stock replacement it could have as little as 5 or as much as 12.
The stock AC DELCO pump runs at about 9 and thats on the edge for this carb. The result being an untuneable burble at idle.

Check EDELBROCK.com for details .Especially if you have noted a rich condition in the past. Look in the troubleshooting section for your carb.
