Unfortunately, it was not just the pilot light that stayed lit. Gas was
also burning through a small leak below the brass nut (at red arrow in
bottom picture at http://www.abrasha.com/misc/heater_536.htm) that
attaches the "pilot tube" to the pilot light assembly. The pilot tube
connects the gas valve to the pilot light assembly. (see top picture)

Those compression fittings are unique to pilot lights - they look
like the same fitting used on a water line, but they're not. They are
machined as a single piece and the ferrule snaps away from the nut
when you tighten it all up.

Go to a HVAC supply store and get a small coil of the 1/8" AL pilot
line tubing and a small batch of the right fittings. Because the AL
work hardens and cracks, if you try cutting and bending the existing
tubing to make it hit the connections you're liable to have a new
leak.

Same thing if the old tubing gets even the tiniest bit scarred up by
the tubing cutter, the ferrule won't make a seal.
