As the title says, I'm looking to replace a nipple that was on my S5 UIM. In the picture, I've circled the area I'm trying to block off. It's pretty large compared to most other vacuum tubes. Unfortunately, this is a rando image from ebay. My car is a ways away from me.

There was one there, but it's dry rotted and fell off during a Hill Climb event. I got lucky and found it when I got back to the bottom of the hill and parked. Currently, I'm using electric tape over the hole, nipple over that, and a wire tie for extra security. However, I'm super worried about that electric tape getting sucked into the intake.

Where can I find a nipple and/or what is the correct size? (I'd like to get it before my next trip out to the car to prep for w2w driving school)

Thanks!

 

i've found vacuum caps all suck, if you want reliability find a piece of hose and bolt that fits very snug inside and zip tie it at both ends. it's not pretty but it works.
