Greetings, all.

I have a 1975 58 LRC with old (inop) fuel qty gauges. I use a tape measure to dip each tank, then then compare the inches of fuel depth with a chart that equates inches to gallons.

My problem is that the chart doesn't show the lazarette tank on it.

Does anyone have a means of converting inches of fuel to gallons for the lazarette tank?

Thanks!
