These kits include everything you need to connect your boost gauge the right way. The plastic vacuum tube that comes with many gauges is difficult to install without kinking or leaking. This can lead to slow or incorrect readings on the gauge. If you want to install your gauge right the first time, or repair a previous install, this is the simple solution. Both kits includes high temp braided silicone vacuum line, high quality brass fittings, firewall grommet, clamps, ties, and full instructions. The short kit includes 78" of vacuum line for gauges in the center console or main gauge area. The long kit includes 112" of vacuum line for A pillar installations. Either kit will allow you to properly install (or reinstall) any mechanical boost gauge with an 1/8" NPT fitting into your WRX. If you have limitted space behind your gauge, you can select a 90 degree fitting that will allow for a more compact installation. Gauge not included.
