Q+A:

Is the Westach K2A8MM 12V or 24V, is it lighted, does it have a harness and install manual in the box. Lastly is it Stewart Warner compatible? thanks in advance
As this is an electrical gauge the K2A8MM is multi voltage 3-30 VDC. It is not a lit gauge and comes with harness, install manual and sender in the box. It is recommended that you use the Westach sender in the box for best results.

Is it possible to buy only the sender for the Westach K2A8MM gauge? I need to change it...
Yes. The oil pressure sender for this gauge is part number 10-02640.
