Hose, blue wire is extender I had to make

Where does hose go? Should I drill a hole?
hello. I put a new air intake on a few years ago. Then I got cancer. I don't remember where the vacuum hose plugs into. Seems to run fine without it. Should I drill a hole?

I bet you have a very early C5 97-98???? Please always let us know what year car you have. In this case it makes a big difference.

That hose looks like the vacuum reference line to the fuel pressure regulator. If you have TWO fuel lines on the fuel rail (SUPPLY & RETURN), then that is the reference line to the fuel pressure regulator.

Yes it should be connected.

There should be a nipple on the old air bridge that it connected it to.

ZIP use to sell a re-mapping kit that allowed you to connect it to a vacuum line on the other side of the engine. That way you dont have to drill a hole.

Yes it is a 97. Sorry I though I put that in my signature but I haven't been on here in a while

I think I remember somehow that the old air bridge didn't fit with the afe unit. So drilling a hole in the new bridge shouldn't be a big chore, it should work as designed then I take it. Thanks for your help

I had this all planned out before I started the project, then stupid Lymphoma came. One of the benefits to Chemo Brain is all the new stuff I'm finding hat I bought for my car. I bought this unit used, previous owner drilled a hole and put a plug in the opposite side. It is capped off. I will look to see if they sell a bridge with a nipple, otherwise just drill a hole and push hose in it, secure with bonding agent

Chech this out

Thanks Bill. I have a 97, I do not have that middle plug that plugs into the air duct. I wonder why 97s don't have that. You can see in the picture the aFe has a hole drilled for it, but it is capped off. What is that Plug for?

Bill Curlee

Its the intake air temp sensor. You should have one installed somewhere. Do you have a newer five pin second designed MAF installed. (2001-2004) That MAF has that sensor installed inside the MAF.
