I am trying to figure out the size of my fuel tanks, front and rear, on my 1985 Jayco 25 mini I believe they are stock to the chassis which is a Econoline 350 does anyone have an Owners manual? the original engine was the 6.9 diesel and I think the gauges may be off and obviously I don't want to run the out to see how many gallons they hold. As much as I can measure a rounded edge tank it looks like the front should hold 21 gallons and the rear 24 gallons any help would be appreciated
