Asked by: Ashneel
Thank you for your question. Unfortunately, we would not be able to do custom lighting and we cannot offer any other lighting types than what we already have available.

i have installed 2 colbalt gauges but the boost gauge light is not as bright as my pyro gauge any ideas as its very dim

Asked by: johny
Should be the same as far as brightness.  Check voltage with volt meter or could be bad ground.

Hi Shaemus, thank you for the question. The 6104 Mechanical Boost Gauge will include nylon tubing and an 1/8" NPT adapter and 1/4" adapter for the engine side connection. Depending on the application we offer a 3/16" T-fitting (model 3291) and 1/4" T-fitting (model 3276) separately.
