Fit right on.. no problem. I doubted it would fit by the description and looks of it, but it did. It's about 3/4 inch in diameter and about 4 inches high. It has course threads and the inside diameter is a good 1/2 an inch which fits loosely over the round gauge marker that slides inside. I know it's weird, but I am thrilled with it. It seems like I always have to do things two or three time to get anything done, but not the case with this thing. I bought it, screwed it on, and I was done. Hurrah!!! Isn't it the little things in life that make us so happy?
