Easy done it many times. Save the old lock ring when you do it the new ones do not seal properly.

I don't know...i heard this from a few people but I used the lock ring that came with the new sending unit and it worked fine....no leaks....they are flimsier than the originals but if you don't have the original one, they do work....just be sure to use the new gasket supplied with the kit.....Of course if you don't have an original lock ring , halifaxshops has some NOS ones he is selling :-)
