My Rodeo Sport has had a faulty fuel gauge ever since I bought it in September. Every time the fuel light comes on then it only takes 10 gallons to fill up. This is not a big deal as 10 gallons lasts me a whole week anyway. I will eventually be replacing the sending unit but I was just curious, how much fuel do these things hold? I have seen specs online stating 15 gallons but others say 17 gallons.
