Questions & Answers

Is it a 3/8 inlet?

Not 3/8". It measures 7/16" in diameter. I originally thought it was 10mm when I posted. My assumptions were incorrect. This time I measured it, and I apologize for the previous miscalculation.

What about water vapors that are reintroduced into the engine along with oil droplets?

A Catch Tank prevents anything from returning to the engine.

How big is the rubber hose that comes with the unit on the inside? Thanks! ?

It's 3/8, according to my calculations. But the truth is that the hose that comes with it isn't very good. It is extremely thin and easily kinks. I went to the parts store and bought one with thicker walls that would hold its shape better.

What was your method for connecting the tank to the heads? Breather bolts or a home-made kit are both options. ?

9932 is the component number.

It really works

5/5

The chrome is of good quality, and it functions properly. It comes with a lot of hardware to make installation a breeze. The only minor criticism (still a five-star rating) is that the included hose is useless. It's so thin that even the tiniest bend kinks it, so spend the $3 and get a better piece of hose before you start.

Can be used on any vehicle without the Bluegrass kit as a stand-alone unit

5/5

It was installed under the left side cover of a Honda VTX 1800 and is the perfect size for tucking away. It allows me to use my aftermarket intake without having to worry about the motor spitting into the filter. Very sturdy and of excellent quality. I was able to use the mounting hardware provided, but the hose was too flimsy, so I had to rerun the vent hose with heavier duty line.
