Q: just to confirm the face of the gauge is 4" correct, as typically the 2-1/2" size is typically the back of the gauge housing not the face?
pls confirm the dimensions?
A: Hi Scott, the gauge you are looking at measures 3" across the face of the outside bezel. If you need assistance purchasing the correct gauge, you can call our parts department at 717-354-8106 X 103
