FAR Reference - Self Fueling

I was just reading both the land lease, and hangar keeper agreements for the
now City owned Morey Airport. (C29), and they both state:

"The Lessee further agrees not to transport, or cause to be transported,
onto airport premises, gasoline or other flammable fluids for the purpose of
self-fueling aircraft."

I've heard it mentioned here that an airport that receives federal funds
cannot make rules like this, and must designate an area on the airport for
self fueling. Of course, they can require a paid 'self fueling' permit, and
charge a flowage fee. But that's a fair compromise, IMO.

Does anyone have a specific FAR reference that I can print out and provide
to a board member? TIA
