I took advantage of the weather being in the 70's vs mid 90's and installed an XDI Evo HPFP and Fuel-it Bluetooth sensor. This took me WAY, WAY longer than it should have.
I watched Pete717's excellent XDI install video (not counting the
speeling errors -

) and thought, looks easy enough..... I was wrong. I was so very wrong. This thing was a complete PIA.
My first issue arose after pulling out the stock HPFP. I was following Pete's video and noticed that I was missing a fuel hose. I was like WTF. So I looked up the official XDI video (
) and there again was that damn fuel line that I did not have.
So, I paused where I was at and came in and started researching if I was supposed to have a fuel line and what is the use of these two adapters, a small 45 degree AN fitting and AN-to-quick connect fuel line. I was convinced that I had received a defective product after waiting 2 months for it to come in. Needless to say, by this point, I was past the beer stage of working on things and poured a nice glass of Makers and while I went down the XDI SHO rut (because hardly any info on install). I looked for pictures or descriptions of what all is supposed to be included with the XDI Evo HPFP and found practically nothing that showed these two adapters I had and only had the missing fuel line.
Fuel line I thought I was missing but was able to reuse -

Then it happened. I came across another video that XDI had for 2015+ SHO's (
). I watched this video and my immediate thought was those adapters are the same ones I have. Maybe I can make this fit on a 2014 SHO. Sure enough, everything he did I was able to also do. Although, removing the fuel line from the stock HPFP (the part not shown in the video @ 3:47) was awful and took me about an hour. The main reason was I could not figure out how to get it off the stock HPFP and did not want to break it, eventually it just came off. Once I got that line off the stock HPFP I then reinstalled it and focused on getting the metal fuel line to line up with the XDI Evo HPFP, this part probably took me about an hour and a half. There were multiple times I thought everything had lined up correctly and started finger tightening only to get half a turn before it would get hung up and seem to start cross threading. I had to bend the metal fuel line down and towards the front of the car before having any luck. I ended up taking the stupid thing apart to rotate it probably 6 or 7 times before I finally got it close and then was able to finally finagle the thing to where I could finger tighten the connection. Thankfully, the Fuel-it Bluetooth sensor only took about 10 minutes to install.
To install the Fuel-it Bluetooth sensor, I connected one end of my GM ethanol sensor into the stock quick connect fuel line. I then had purchased a line specially for this from Ortiz and was able to connect it to the other side of the fuel line and GM ethanol sensor. After that, I connected the power and ground for the ethanol sensor and Fuel-it adapter. I got into the fuse box and used a fuse tap for the power and tapped into one of the fuses, not sure which one, I didn't care at this point, I just wanted it to work. While in the fuse box, I noticed that there are so many connections in the fuse box that do nothing, it could be half of it's size or less. Anyways, I used that for power and for ground I simply connected it to one of the chassis grounds near the battery. As mentioned, from start to finish, I likely had 10 minutes in installing the ethanol sensor and wiring up the power and ground. This part was super easy.
Anyways, just to get it out there, it is possible to install the XDI Evo on a 2014 SHO without their fuel line and I am wondering if they have updated things to only have this setup going forward.
Another note - I am still running the GH AO for this pump and have noticed no difference at all in performance or drivability. I will be running out my tank on this setup before switching over to the E30 tune.
