I don't own a 19mm wrench, but I do have a 3/4" wrench and remembered from various past encounters with 19mm nuts and bolts that my 3/4" wrench fits nice and snug. Thankfully, I remembered this before buying a wrench I didn't actually need. By the way, I have my Tousley receipt in front of me and I paid $104.15 + $10 shipping ($114.15 total). By the way, be sure to mention special internet pricing if you order by phone. Also, the brass plug should be 1/8 inch pipe thread. When I brought my housing into the hardware store, the 1/8 inch would only thread in 2-3 turns by hand before tightening up. However, once you get the Teflon tape on it, it will turn smoother into the extra port. Also, I found a counter sunk 1/8 inch pipe thread brass plug that IMO looks and works the best. The plug is just over 7mm tall and fills the extra port neatly without sticking out. I will also list the part numbers as a convenience to anyone checking out this thread.

Thanks for posting the part #'s and the price. I couldn't find a counter sunk plug the day I looked, but that would work very well too.

You can get away with the 3/4 on the sensor because it's not torqued down very tight. If you use one a 3/4 socket on the lug nuts or something torqued down a little tighter it could round off the bolt or nut. I always go with the correct size, but my OCD won't let me do anything else. :)
