Steel-core 7.62x54 would probably do it well enough. And you can buy that by the case, cheap.
All you would really have to do is get fuel dripping out along the surface to a point where it would ignite from heat from the engine exhaust.

Thanks for replying--I would have gone to my grave not even considering the fact that rocket fuel has oxidizers mixed in, but the search you just sent me on set me straight.
Before they started supercooling the LOX, it was even easier because heat transfer into LOX tanks is conventionally managed by boil-off (in launchers without supercooled propellants, latent heat keeps the liquid at a stable temperature and a trickle refills the tank continuously until a minute or two before launch).
