VanAgain has a kit, but I don't think it is on the website.  You may have
to call and talk to Ken.  I would suggest, if you have the time, to drop
the tank and see what you actually need before ordering.  I did not fool
with the sender because it was not leaking and I had heard of reports of
difficulty in installing the new gasket correctly.  There are three
grommets on top you should definitely do. My plastic cross-over tube was
fine.  I replaced the neck gasket and all the small lines from the vents.
No more smell on fill ups.
