I installed this back in early January, done several track events, haven't had any issues since. No codes or signs of low fuel pressure.
Yes the flexible hose looks alittle awkward when installed but nothing to be concerned about imo, it's not kinked and nothing is pulling on it.
If the fuel rail ever leaks, the hose portion can be replaced fairly easily by any custom shop that makes hose connections. But I don't see that being an issue. IMO it's worth the small risk to have the extra protection of the filter.
Compared to other setups on the market, this one seems the most OEM-ish, it is mounted securely with a bracket, not just flapping around like the other ones, it also relocates the fuel presssure sensor to after the filter, allowing the DME to adjust pressure like originally intended. Others will see a small drop in pressure at the fuel rail compared to this setup.
