RCI 2161 A in TJ

Im in the middle of my rear stretch build and am about to pick up a fuel cell. Seem like the RCI 2161A is the most popular. I plan on using the Genright adapter to use the stock pump. But what else do I need as far as plumbing? I saw the 4x4 buyer group sells a whole installation kit but is it really needed?
OR is there a way to buy the cell and adapter ring and just hook it up to what ever stock connections there are?

Also is a duel pick up system and foam needed? And how much foam is used in the tank?

If you plan on using the GR threaded ring, DO NOT use the 2161. You'll end up with a pump that doesn't quite sit on the bottom of the cell, leaving you with unused capacity and an unsupported pump.

If you want to use the GR ring, use 2162. The height and width dimensions are reversed, allowing the pump to sit on the bottom when fully compressed and the plastic retaining ring threaded onto the GR ring. This setup is superior to the standard 2161/flat ring setup in several ways:

You get a lower fuel cell--it looks cleaner and gives you more room to mount something above it (like the spare) if that's your cup of tea.

You can easily remove the fuel pump without breaking the seal between the adapter ring and fuel cell. This is invaluable.

Your fuel pump is supported and you can use all of the fuel in the tank. Your gauge will be more accurate because of this, as well.

The only problem is the 2162 won't quite fit behind the back seat if that's your desire. I don't run a rear seat and have the 2162 setup mounted right behind the front seats on the forward edge of the 'cargo' section. I've ran both the 2161 and 2162 with the GR ring and factory pump....take my advice and skip the 2161 altogether.

Tip: You can't use a standard flat adapter ring with the 2162 and factory pump. The pump won't compress far enough to fit. But I don't know why you'd want to use a flat ring anyway. They're a PITA and are completely inferior to the GR ring. But if you have to use a rear seat, the 2161 with flat ring will allow the pump to sit on the bottom. So, you've got to decide between using a rear seat or having a superior fuel cell setup.

As for the 4x4groupbuy fittings and lines, you need to make sure the size of the fuel line on your frame rail is correct. And those are probably just Summit brand lines and fittings. You want Aeroquip lines and fittings or else be prepared to deal with fumes. I've done fuel cells the wrong way and the right way so if you have any other questions, just let me know.

Thanks man, Thats good to know about the 2161 vs the 2162. At this point I'm passed having the rear seat. Was planning on building a tire carrier into the cage after the stretch anyway.

So with the 2162 a single pick up system is enough and I shouldnt have to go with the duel? Have you ever had any starvation problems with the single pick up?

For the fittings and lines, ive never dealt with any of it. Whats the standard size of the stock line from the rail? I keep seeing -6 AN and -8AN show up but have no clue what that refers to. Just to get it up and running which Id like to do before I cut into the truck, will the GR ring, stock pump and lines work for now? Or should I just pick up the Aeroquip kit right off the bat?

This it?
