1875 Lund with smartcraft guages

[jimordway]

I bought an 1875 last fall with smartcraft gauges. I had those in all my rangers thru the years. The fuel used totals and the gph were priceless to me. On my new Lund, I get a reading on the gph but nothing registers on the gallons used. Always at zero. Any ideas. I used this feature and zeroed every time I filled my Rangers in the past and miss it.
Thanks,
Jim
