If you install one of those 12 or 24v electric fuel pumps do just cap off the mech fuel pump? Leave it in the motor? I Googled if a kit was available to remove it and plate it off.
 
This is the same diode electric fuel pump I run my carbureted 72 FJ40, they are like $10 and last about 10 years.
Pic is my fuel transfer pump, because holding up a 5 gallon can of gasoline is a PIA. Cost about $50 each for the ones I made several years ago.
Its fused, water proof switched, filtered, has a 12' power cord that can connect to the 12V battery or the cig lighter. 5' draft hose and 20' delivery; you can swap hoses and harvest fuel from tanks. Will also move diesel. This a low pressure system for carbs - an I have run rigs with it and a gas can.

2FE setup, you will need a higher pressure pump than just a generic electric pump to run fuel injection
if you had the 3fe for the parts, there is a block off plate stock on the block, as 3F's were around the world still running mechanical pumps

Oh awesome! Thank you so much for your help, I'm dealing with an FJ I got a good deal on, a frame off resto that they gave up halfway through. Runs and drives but there's a few things that got haphazardly slapped together.
 
You are welcome, lots of smart helpful here abouts.
Perhaps some free download manuals

Coolerman's wiring diagrams and parts

There is also a classified section for parts and such and there is a very nice selection of vendors

Oh yes! I was looking at that, I have a few extra parts that came with the vehicle, some still in the box, I was going to post a few of them in the classifieds. Thanks again!
 
the above
or
a plate from a 3FE engine

why are you wanting an electric pump?
The FJ I purchased has one on it, seems to run ok, its just one of those cheap $90 add ons. I'm trying to figure out if I should hook the old pump back up or if there was something wrong with it.
