What kind of a cost would I be looking at to convert from a mechanical to an electrical fuel pump? Is it a really involved process? My mind is telling me it shouldnt be but then again I don't know all there is about Jeeps
You'll want to wire it with a relay and fuse. Also, it's not a bad idea to get a switch that will kill the fuel pump if there is no oil pressure. Something like this:
There's two ways to go. You can run an in-line pump like will e, or you can run an in-tank pump. In-line pumps are way easier to install and replace in the field, but in-tank pumps are more reliable and durable. I have no strong feelings either way, but opted to modify a Chevy in-tank pump to match my Chevy based fuel injection. In-tank pumps don't loose their prime or over heat because they are submerged in fuel all the time. As will e knows, in line pumps may lose prime or overheat, but you don't need to drain the gas and drop the tank if it does burn up.
Again, I have no strong feelings about one or the other. Your rig is nice enough to justify going full Monty with an in-tank, but since it's toughest duty is hauling boy scouts, I think an in-line is up to muster.

FWIW: I run an inline electric pump. I currently run a Holley red pump but have run the Airtex in the past. Based on my experience, I would invest in a quality pump, if you are running inline. I had 2 Airtex pumps go bad on me. Each one lasted about a year. After that, I installed the Holley and haven't yet had an issue. The Holley is rated to flow more fuel at a higher pressure. I suspect that it being "overbuilt" for my application means that it will last longer. Only time will tell.

I just finally did the swap after years of prep. I installed a revolution electronics switch and an old red top pump. Works well, pump is loud but it's flowing. My Carter mechanical kicked the bucket after several years so I had no excuses not to go electric.

Electric too here on both rigs, carter P4070, a bit more $$, $65 at summit plus shipping. As for noise, I installed it on the frame it is very quiet, the carter comes with an isolation bracket with rubber donuts.
Supposedly the pump has to be installed closer to the gas tank, but space is limited in the back with the carter P4070 -it sits upright-

I am running a in-tank pump and relay connected to a switch inside. Between the pump and relay it was about $100. I was running a Holley Red Top but it went bad and was out of warranty. I use a cheap pump from Advance Auto. I would suggest using a fuel pressure gauge also.
Tomorrow we may face destiny, we may fight and die and fall to the fires of perdition, but tonight is ours, and we drink and make merry.
I have a Holley Redtop and a Holley Mitymite. I use a relay and run a ground from the battery to the pump--at the pump the grounds tie to the frame. Im curious to see which of the two Holleys last the longest. The Redtop is on 3 years now and the MM is 2 months.
forgot to mention, that no relay and no oil pressure switch for both rigs. The pump seem to last about 10 years, mileage or hour of operation should be the data to use, but who has an hour meter... and we have that California toxic gas with additive to make the engine run cleaner... but the engines are burning about 12% more gas...

Just an FYI the new carter's made in the last year or so are made much cheaper than they used to be. Made from Taiwan parts and only assembled in the USA. Had 2 go on me in a month
I purchased a Holley Red and was quite disappointed in it. Noise and failed 12 months in. The Precision is much quieter, cheaper, has a lifetime warranty and is stocked in O'reilly stores in case I actually needed one. The Carter/Precision design runs fuel through the motor to keep it cool.
