UpdateMost of the installs are complete, and we're a little sure about the line so I've emailed XDI the following:
"
1) Are both ends the same on the line? Visually it's hard to tell them apart
2) Is this line rated for ethanol use?
3) We're barely getting 3 threads of engagement with the fuel rail, is this normal? Tried both sides.
Either end threads into the Full-Race HPFP just fine.
"
Will post what we get back from them. Everything else has been smooth sailing thus far *fingers crossed*
1) Both ends are the same
2) This line has been used across all fuel types for the past 10 years. It's technically a hydraulic hose with a proprietary compound, so the manufacturer doesn't publicly confirm fuel compatibility to protect their IP, but it's been run on ethanol, pump gas, race gas, methanol, and even hydrogen, including in actual motorsport applications. We're working with them on getting some documentation together, since trust in this market has taken a hit after other brands' lines have had issues over the years.
3) Snug it down fully by hand first to avoid any cross-threading. Once that's done, you can go over it with a wrench, but honestly a good hand-snug is usually more than enough for these.

I also spoke with several other people running different lines including XDI, 4-piston, and Full-Race V3.
The other personās tech confirmed that with the wrench in the end they also achieved 3 1/2 threads of engagement which is what we also ended up with, and itās held up the last 4 months. They were previously using the V3 line which cracked.
I was also advised to use heat wrap on the line as the 1.5ā longer flex length means it can/should be routed from the hpfp to fuel rail slightly differently to avoid kinks, but that means it runs next to the coolant hoses, which are particularly hot. Thankfully we keep just the right part by Dream Automotive in stock.
I will be cross-posting this on the thread about HPFPās and fuel lines, itās valuable information for everyone that will be easier to find there. Weāve unofficially confirmed fitment as itās on the car now, but Iāll guinea pig as well for some time and if thereās no issues weāll consider adding it to the kit as optional yet recommended purchase.
Photos below for context. The dream shield has to be trimmed to length, or just use any heat wrapping material that you have available to you. We used zip ties as the velcro couldnāt fully hold as the wrap is meant for thinner lines in the engine bay.
