Electric Fuel Pumps

Thinking about swapping to an electric fuel pump on the Jeep (4.2L). I've been dealing with a fueling issue for a while where if the Jeep has been sitting for a while (more than two days) I have to wait for the pump to pump fuel back up to the carb and fill the bowl. I also just don't trust store bought mechanical parts anymore... too many lemons.

Is there any reason why I should NOT swap to the electric pump? I would obviously wire it correctly through an oil pressure switch and relay.

I do also plan to swap in a 4.0 based FI system, so I'll need to accommodate a fuel pump at some point in time anyway. By doing this it will already be wired up and roughly plumbed.

I've been looking at the Carter brand of pumps, fwiw.
 
If you are going to go 4.0 fi down the road, just do an intank pump now and regulate it down to 5 or 6 for the carb until then. Run all your FI hose now with a pump that will work for the FI, so you don't have to do it again later and it will make things go quicker later as well. I would highly recommend an in tank pump vs external, will last much longer and won't have to worry about it burning up. You can get a cheap intank pump for roughly the same price as a decent low pressure pump.
 
Look around at Walbro pumps. I've had nothing but good luck from them.
 
I would go with an in tank pump if possible.
I did a cam swap in my sbc and accidentally put a cam in with no lobe for a manual fuel pump. I've killed two electric fuel pumps and the car hasn't left the garage yet. Most cheap electric fuel pumps are junk.
 
Most of the CJ guys recommend the Airtex E2000 pump, which is stock on late '80s, early '90s EFI Fords.
For ease of install this is the route I'm thinking of going; is in tank really that much better?
 
You want you pump as close to the tank as possible. The pumps like to push fluid....not pull it.
 
There's a reason most vehicles have in tank pumps only. Noise & longevity mostly. An e2000 is superseded by a different part number at Advance. Look it up by application if you go that route for availability. Definitely get one at a local store if you go inline. It's much easier to change in the side of the road. Maybe even go so far as to keep a spare.
 
The best low-pressure carb pump I've found is this guy, right here. https://www.amazon.com/Carter-P4070...522066239&sr=1-21&keywords=electric+fuel+pump It's big, howls pretty good, but lasts forever and puts out plenty of VOLUME. Low pressure, high volume. You won't starve your carb with this one. I'm running a Weber DGEV off one. Bought it because it was for a friend's car, and I wanted a pump that wouldn't leave him stranded. SOO much better than the typical ice cube or inline pumps. It's been on the truck for about three years now, and it's still working fine. I plumbed it with the return-style filter your Jeep already has, and no regulator. Works beautifully.

Yep, that is THE pump I had in my amazon cart before I started going down the "why not just go ahead and install the EFI pump" path.
 
If you go e2000, make sure it is mounted below the tank and as close as possible. Also need to make sure that the line from the tank to the pump is a large as possible and rated for suction. Those pumps do like like to pull fuel, but will suck a hose shut and you will end up burning them up.

As said, if you going the EFI pump now... I would just find a xj/YJ/TJ fuel tank and swap it in pump and all.

I bought the moto built ring and used the stock XJ fuel pump/sending unit in my tank in my fuel cell
 
Have run the same fleabay ($19) "e2000" pump on my TBI setup for 9 years now without a hiccup... BUT have a spare on-board ALWAYS! :D
Mine's mounted to the inside frame rail (wrapped with a beer koozy & zip-tied in place) with a filter *before* the pump and using 3/8" FI hose from the cell.
I worried that the 3' from the cells pickup tube to the pump would shorten it's life, but that was 4-5 years ago?
 
I use an Airtex e2000 on mine for the tbi , it’s mounted on the frame rail about a foot or so forward of the tank, never had a problem with it , you already know you need to regulate it down for a carb. Mine is not noisy at all.
