Re: MD11C Gauges
While it's true that gauges and senders must match, if you're not worried about cosmetically matching the existing gauges, you can easily buy senders/gauges from any number of automotive or marine suppliers. There's nothing special about them except that they must have the right threads for the engine ports and the right temperature/pressure ranges. I just bought 4 complete sets of gauges for Yanmar engines from Defender for about $70 each with senders. About 2 years ago, I bought a complete oil pressure set made by Faze for $35.
