Use as intended, make sure you measure the diameter of what you are blocking off.

I needed this larger cap for the vacuum port on my new LS3 engine. It fits perfectly.

It's ok but over priced I could have just use a hose and seal of the end and it would be the same thing.

I crammed a 3/8" cap on a 1/2" outlet and it split causing a massive vacuum leak. Don't do that. Buy the right one. These are good quality. Buy these.

I expected these to fit on the back of my Holley carb. It was loose fitting and fell off, one was actually smaller in diameter (not by much) than the other. I'm fairly certain the port requires a 1/2 cap, but I'm not sure hence the 4 out of 5. Came quick semi happy.
