Electric Fuel Pump in 72 CJ5

Is there any reason to not use an electric fuel-pump in my 72 CJ5? I have one in my 69 Bronco and it works great. If I go with an electric pump can I just pull the stock mechanical pump and get an appropriate plug to screw into the engine block where the mechanical pump was?

 

I have one in mine because of the fuel injection. It's an inline one and it works great (except the time it went out on trip and we had to steal the one off the truck so we could wheel while we waited for a new to be shipped to Gunnison). I have a high output one so replacements are a little hard to find sometimes.
Edit: I forgot to add, we left the old one in and plugged the input hose on it with a large bolt.

 

The electric pump should be fine as long as the pressure delivered matches the original mechanical pump, and if you wire it so that it shuts off if the engine dies (on when starting or running only). If you go upside-down or on your side with the key on, the electric will spill gallons of fuel very quickly. Typically these are meant to push rahter than pull fuel, so locating it near the fuel tank is better than under the hood.

 

Thanks for the input. My plan is to put the electric fuel-pump on the frame rail close to the gas tank and probably use a larger Cherokee style fuel-filter in-line also. I would also leave the smaller fuel-filter that is up near the carb and then just put a bolt in the intake for the mechanical pump as Jeep Gal suggested. Sound reasonable?

 

Sounds like my set up. It should work.

 

JMO - unless you have a good reason to have an electric pump, there's no real advantage to them over mechanical pumps for street engines. The EFI engines need them to generate enough fuel pressure. Race cars use them to deliver a lot of volume. Mechanical pumps are very reliable, simple, and you can carry a spare for a few bucks, plus they are available at any FLAPS.

 

I'm am in Breckenridge where the altitude is almost 10k feet so I need all the help I can get. My 69 Bronco uses one and it is a very reliable starter even when it gets cold.
