I'm using Smiths Classic gauges on a Ford sender on my temperature and fuel gauges, they both are not accurately reading do I need a voltage stabilizer?
Smiths, CAI temperature and fuel gauges do require a 10v (voltage stabilizer), but they would also require a Smiths Temperature sender and the Smiths fuel level sender.
Each manufactures gauges are designed to be used only with that manufacturers senders. A mismatch rarely reads correctly.
