In cab fuel tank capacity?

Anybody know what they hold? It's a 74 W200 if it matters. Trying to get a feel for the fuel gauge. It said a little over 1/4 tank and I put 17 gallons in it to fill it up so I'm thinking maybe 22 or 25 gallons?

I don't know, but it will be listed in the owner's manual

That would be great if I had one.

From what I can decifer in the manual, 25 gallons.

Great, thank you.
