I am happy with the product. It came faster than predicted which is always a plus. I think that instructions should be given for removal of old nipple and heater for beginners though.

Wow! after putting up with a non-working pre-heater and leaking pre-heater gaskets and the pre-heater wanting to spin off with the filter each time I replaced it I stumbled across this great product. And it has a "Allen" hex recess in it to tighten it in place! The original pre-heater nipple has slots and they are very hard to engage. I now have no more leaks!

Works Good
