| I have the TTZD ([ http://www.ttzd.com/tech/boosttech.html ]) write up for boost gauge install. One of the steps that seem unnecessary: 20. Cut the excess hose from the engine to length. Using a 'barrel' connector, plug the hose from the engine to the short hose on the gauge & plug the illumination wires into the correct wires from the lighting 'pod' 2 questions: 1. why don't they use one piece of hose to length?
2. my SPI gauge came with a barrel connector with metal insert installed in barrel connector (seems like a reducer of the air pressure or a "boost jet" type deal), does that barrel need to be installed for the proper operation of the boost guage?
