Alright it's been almost a full month since my last post where I got it on the road. I never did get some time behind a lense with it cause I've been trying to get it ready for a shakedown next month. I've already got a lot done since then so here I go again playing catch up.
I figure we can start with some fuel cell stuff. I got the fuel and breather lines plumbed and the electrical connected.
I originally used some fuel rated 5/16" hose to temporarily run it for that day I got it on the road. Even though that hose is fuel rated the permeation is horrible. The outside of the hose stays dry but the smell of fuel goes right through it. I swapped it for some Fragola -6 6000 series PTFE lined hose. This hose is a little nicer than the other -6 PTFE hose I used on the power steering. After hooking it all up there's zero fuel smell permeating through it.
At the fuel pump side I used a -6 x 3/8 adapter, and for the hard-line under the tub I used a -6 x 5/16 adapter. I originally used Fragola fittings as that's what I've been using throughout the jeep but I found the o-rings in their adapters were way too tight. I had to force them on which tore the o-rings. I ended up buying some cheap, no name adapters from Amazon which worked like a glove. I'll give Fragola a call and let them know so they understand their product needs a design change.
To run the fuel line through the tub most people run it through a grommet, but it's not necessarily the safest way to do it. I used a -6 x -6 bulkhead fitting and a 90° fitting on each end. This prevents any chafing on the tub entirely.
Below the tub, from the AN line to the hard-line it was straight forward. I actually had the perfect line already made from when I built my power steering lines. I made one extra accidentally and it fit perfectly here for the fuel line. I connect that fuel adapter to the end and it snapped right onto the existing hard line. The way the hard-line bends outward of the frame is kind of a strange angle but it works fine.
The breather hose that comes from the rollover valve on the passenger side of the fuel cell was real simple. Since this hose isn't under pressure I used simple AN hose end clamps. To run it through the tub I used a 5/16" hose barb bulkhead fitting instead of going the AN bulkhead route. Using an AN bulkhead like I did on the fuel line with hose end fittings on each side would've been $60-70 more expensive which would be overkill anyways. On the bottom side of the tub I ran the line to the outside of the driver fender and terminated it with an air breather filter... Btw to get all technical about the routing of a fuel cell breather hose, the buggy/comp/trophy truck guys run the hose 360° around the fuel cell and up on the B pillar and back down before exiting to a vent-to-atmosphere termination. This ~720° of bends prevents any fuel from leaking out of the fuel cell during rollovers and off camber situations. Most jeep guys that use fuel cells just run it straight out of the tub cause they aren't race cars. Also, if we get off camber enough to start leaking fuel out of the breather then we're already at enough angle to have low oil pressure. Just wanted to put that out there.
For the fuel pump electrical I just spliced into each wire and extended them. Super simple.
Moving onto the fun stuff - electrical and wiring.
We didn't use our winches much unless we went out to the hammers trails. Out there the winches got used so much that we ended up just keeping our winch remote inside the cab while it was plugged in the winch so the cord just sat outside and flipped on the hood. I have a wireless Warn adapter thing but the delay on that thing sucks.
Going through that I knew I wanted to hook up my winch to an in-cab rocker switch. When I designed my dash switch panel I made sure to keep an open rocker switch cutout just for this.
I initially just cut my remote hand switch off of the cord so that I can leave the pin end connected into the winch. I found out one of the pins got damaged and pushed into the connector so I had to hard wire it into the winch itself.
Here's my winch remote before I cut both ends off of it.
I routed the cord along the frame, through the firewall and into the dash. Cutting off the ends of the remote and using the cord made it super simple due to the colors.
Here's the winch with the cover off.
To route the cord through the top of the winch I drilled a 3/8" hole through the side and used a grommet that fit really snug around the cord.
I've seen people splice into each wire but I decided to just crimp terminals on each end and land them on each post of the solenoids.
It's important to know that Warn changed the colors at some point so if you were to do this, this is important to know. The old colors are as follows..
Brown = switch ground
Black = winch out
Red = motor ground
White = 12v + power
Green = winch in.
And it here it is all done.
As you can see the winch fits insanely tight on the bumper, making the approach angle the best it can be.
I also wrapped some new synthetic rope on it. This will be the first time this winch has had synthetic so I'm excited to feel the difference.
I wanted to take some time to talk about this fairlead. This is the HOSS fairlead that Brennan Metcalf designed. I'm a big fan of what the guy designs and this product is no different. A lot of thought has gone into this and the attention to detail shows. This design allows synthetic rope to smoothly enter the rear of the fairlead, preventing the winch line from fraying and eventually failing. And the fact that my winch sits so closely to the fairlead makes this perfect for my application. You can read more about it on his site.

Here's what the back of the fairlead looks like. And he includes a thin plate of stainless for your application depending on how thick your mounting plate is.
Along with the winch wiring done I also hooked up my fans. I used triple throw rocker switches for these for a specific reason. In the normal state these switches will be in the down position. When the jeep is turned on the fans will come on only when the fluid gets to proper temp. The switch LEDs stay off until the fan is actually running so I know when the fans come on when I'm driving.
I can move the switch to the center position to completely kill the fans for whatever reason. Example- going through a deep water crossing to prevent shorting the fan out or if my battery has low cranking amps I can kill it before I key the jeep on.
Or I can move it to the up position to bypass the thermostatic switch. So if it starts overheating I can shut the jeep off but leave the fans on.
Here's essentially how the wiring schematic looks for one fan circuit. Both circuits are set up the same individually.
EDIT: I forgot to label the switch to the left in the picture below. That's the ignition switch.
And here's my dash switch panel complete.
