Try Plug N Dike powder. Mix with water to a clay consistency. Press on the leak. This stuff hardens when exposed to petroleum. I've used this in the Fire Service, for emergency gas leak calls for many years, with great success.
Good to keep handy. I Keep small portions dry in a ziploc bags, if I need it...add water to the bag, squish it up and apply.
Hope this helps.
