Here's some I have, you can buy packs with assorted sizes at any auto parts stores.

I'm pretty sure I see where the line connects to the throttle body. Its the only rubber line I see that attaches and its on the left top part.
That's it, if you have the AC and backing plate off its right at the 11:00 position.

Cool. I can actually see it without the AC or backing plate being off. Maybe because I have a Big Sucker? (that's what she said )

Hogpro, Please answer this question. Normally, I would just blow this off, but you are a forum Sponsor/Vendor so I assume people have a higher regard for your opinion. The information you have posted in this thread could cause damage to an engine. I can appreciate the fact that you have 80k trouble free miles on your engine, but that still does not make this correct.

Basically you have roughly an 1/4" line leaking vacuum. Now, this is unmetered air, so it should not cause a lean condition, but it is a 1/4" unfiltered hole in the throttle body. This would be exactly the same as drilling a 1/4" hole right through the air cleaner. I'm sure you would never condone that.

I'm interested in what HogPro has to say also.

I bought some vacuum caps today in various sizes because I wasn't sure what size it is. I think its a 1/4" line but again, not sure.

Yeah, I'm not sure on the size, just threw a number out there. It is likely more like 1/4" like you said.
