You guys ready for more chaos to add to this. Read this. This is in reference to the soft line that has been debated works/does not work. From what I gather from this, is that all these companies cradle each others balls, and none of them are going to do the right thing and make a soft line that works with the Full Race pump period.

Yes they gave me the same answer before i ordered. I just risked it. So far so good after 1 month of daily driving with some pulls!

Has anyone tried the JSR V4 as an alternative to Full race or XDI high pressure fuel line?

The JSR HP fuel line has a different conical taper to the FullRace HPFP female fitting.

So it'll only work on XDI HPFP? Either way, this HP fuel line with an XDI HPFP, I believe would be more reliable since its a stock fuel line that's been modded and I haven't seen any issues of line cracking. I still have the HPFP, but I've been thinking of upgrading the turbo, but this high pressure fuel line issue is keeping me from doing so.

Me too man, which is why this thread was started.

I still want to hear from the people that use the JSR OEM modified High pressure line. From what I've seen people from the FK8 forum, people were using this line with the XDI pump, with no issues, especially as this was the only solution before the Full Race HPFP.

I drilled my factory line, so it's essentially the same as what JSR has done. No issues to report.

Not yet, waiting on some stuff but hoping by the end of the month to have an update.

Any update?
Also I wanted to ask a few things related to the this topic:
1. Does the XDI, not come with a HP fuel line? If it does would the JSR option be a better option?
2. If I installed the canflex, I've seen that most people also change some parts on that, but I not sure from where can someone explain this to me.
3. If I do install the canflex and upgrade the HPFP do I need a filter for the fuel system, if so what is the best and why?

Update on my fuel system install, pasted from another thread. This is the summarized version:

We had a few questions on the XDI HPFP flex line that got answered along the way. Both ends of the line are identical, it's rated across all fuel types (including ethanol, race gas, methanol, even hydrogen in motorsport use, though XDI doesn't publicly advertise fuel compatibility to protect their manufacturer’s IP), and 3 1/2 threads engagement into the fuel rail is normal, hand-snug is really all these need before a final wrench pass.

Install came back together clean, checked every fitting before first start, no leaks at the HPFP, and it settled into a smooth idle after the initial crank cycles as expected. Idled 15 minutes with no codes, then took it for a shakedown drive on the basemap with no inconsistencies.

Logging is now underway for DRob ahead of the dyno. Got a 60-mile drive in with the 15-minute steady cruise and WOT 3rd-gear pull from 2000rpm both logged, still need to recapture the 15-minute stop-and-go (FlashPro missed it twice) and the cold start/idle log (FlashPro missed this as well ), planning to grab both tomorrow. Full tune on Shell 93 and Ethanol is expected in the next 1-3 weeks.
