Is an adaptor available to run this tach Product # 1398-00408 on a Cummins diesel engine? Thanks

Asked by: TinTin
Thank you so much for connecting with us. Our 9112 Diesel Tach Adapter uses an alternator probe and will trigger a standard ignition tachometer, including model 1398-00408. Here is a link to the 9112 which will also include a link to the instructions for additional information:

I wanted to know if you guys sell a cup to convert this tach to a dash or column mounted gauge instead of in-dash

Asked by: MadElky65
Thank you so much for contacting us. At this moment in time, we do not have a cup for the 3 1/8" tachs and speedos. That will change in January of 2018 when we'll be rolling out both a chrome and a black finish cup to do just that. Hope this helps!
