Hello,
I have two pipes that I don't know where they should be connected to :
1. A vacuum pipe at the EGR solonoid


2.A pipe that runes in the back of the engine, I think coming from the fuel regulator and just ends there

Hey itzikbns,
ALWAYS start with a model/engine when asking questions!

As I found out that you have a 2.8L......

See photo below

EDIT: As your photo 2, please show more than the line only in the blue circle...


As few photos for the vacuum lines:

quick question related to the diagrams. where does the cruise control and its canister get vacuum from?

From a tee of the fuel canister line

A simple Google image search for "Fiero EGR solenoid" turned up this gem of a post.

quote Originally posted by buddycraigg Here: this is where all the hoses plug in to There is a short hose that connects the side port and the line going to the vacuum sensor. This hose isn't made of normal vacuum line and rots out badly. The fresh air port on the back of the solenoid is suppose to have a hose that goes to this metal line on the firewall. If you ever wondered why they didn't simply remove the large pipe that use to go to the valve cover when they did the recall, that's because it's attached to the small line. big pipe with GREEN arrows. small pipe with RED arrows And finally the small line connected to the air cleaner. The hard plastic lines connected to the solenoid.

I edited the GM vacuum diagram as a complete drawing with ALL of this information........

Thank you all amazing people, really helpful, I fixed the solonoid pipe, don't know how did I missed it... I will find the connection in the back for the smaller pipe...but if it is only grease air than I might even leave it like that

currently I am a little stuck with water pump removal, I removed all the bolts and nuts, placed them over at the new pump hols and they are all filled but the pup is still stuck...
Any ideas?

TX,
I got a lot of helpful information from that posts, one of it me sion the need to disassemble more bolts, using a fiber optic I have located two additional bolts on the lower side of the pump, please see image below, I took out the one marked blue but the pump is still rock solid, I will remove the other one tomorrow and see if it would help, as I understood the pump should get off without too much force

12 Bolts on the V6 Water Pump


And YES - double checked that you removed 12 bolts and then do not force the pump off as only the gasket is holding it.......

There's no need to guess which bolts are the water pump bolts. If you start removing unnecessary bolts, you're liable to be loosening the timing chain cover, which could lead to all sorts of leakage issues.

I hope you at least installed the clamp before loosening/removing the water pump bolts.
