You could try one more new set of bags and put them inside the old
bags. That might protect the new bags from the wear and tear that may
be causing the leaks.

I couldn't imagine trying to stuff a new airbag inside an older one, as the
hole is rather small.

Sorry, I didn't explain very well. Since the outer airbag is only
really for protection, you can make a big enough slit in it to get the
new bag inside. I then put some scrap nylon material between the new
bag and the hole (so the tape wouldn't stick to the new bag) and taped
over the hole it with good old duct tape. Leaving the slit open a bit
when taping allows for the outer bag to expand. On my first attempt
the tape ripped off and the hole opened up when I inflated the inner
bag.

You also have to remove the valve or infalting tube from the outer bag
to let the one from the new inner bag poke through. And make sure the
inside out the outer bag is very clean, any sand or grit in there will
cause problems.
