Thanks for the quick responses everybody. I had a feeling that that was my only option. It's for a V8, I think I'll order that one from Classic parts. Has anybody used that V8 one before? My engine is mounted pretty low and my only concern is that the wire running from the gauge to the sender may not be long enough.
