This kit plumbs Radium's 20-1139 fuel rail into the YXZ's factory quick connect and includes a fuel pulse damper to replace the original, which not every Radium plumbing kit does. The damper's vacuum port is tapped #10-32 and the kit supplies fittings for it including a plug, since these Yamaha engines do not need a vacuum reference. Radium recommends a wicking threadlocker such as Loctite 290 on that plug.
