New to me 7010 is losing fuel through the cap. Put a new cap on - no change. First 7000 series I have had that does NOT have the auxiliary tank. Is this characteristic of a single tank tractor or do I have something else going on?

Check the gasket on the fuel cap. Had the same thing happen on a JD cap. Replaced the original one with a new one and it still leaked. Turned out the gasket on the new one wasn't centered and one edge didn't contact the filler neck. I made a new gasket myself and it has been fine since. Hope this helps. Might check the filler neck for damage too.
