Poor Quality, Leaked/DANGEROUS
Expected. The fitment was off, so it didn't line up properly with the fuel rail fitting. Had a slow leak when on. DANGEROUS, especially on high pressure fuel system.

Serves the purpose it’s intended for. I just found it leaked a wee bit, no matter how snug it was tightened
