The above diagrams are for both a 305 and 350 as the TPI intake is the same for each. If you need something specific send me a PM and I will try to help as best I can.

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
my evac canister is located on the driver side. I have an 85 Iroc with a 350 TPI from an 87 Iroc. the problem i am having is when i remove the vacuum line that connects under the throttle body my idle rises but when i connect it my car surges at about 500-700 rpms & wants to turn off.
I noticed that happen after i removed my throttle body to clean my IAC valve. ive adjusted both my IAC & TPS already.

yes i did thats why i am puzzled to what could be the problem. my vacuum line was cracked where the T is formed under the TB, it had probably been like this for quite some time. I repaired the vacuum line & that is when my problem started. I will try to set minimum air once again & hopefully it fixes my problem.

In other words, "yes" the check valve is needed if you want the HVAC to work properly.

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
i have a similar problem on vacuum hoses but i figured it out for my 1986 305 TPI but wen i try to figure the 1989 350 TPI its hard and confusing for me i have put sum pics sorry dont got editing image to highlight what im trying to tell u so ill be as specific as possible hope fully anyone who knows this can help
remember this is on the 1989 350 TPI
Fisrdt pic is of the right side of the plenum the fiting or niple that doesnt have a hose where does that go to?
the second pic is the same as the first just at adifferent angle now the hose that is closest to the runner where does that hose go to cause its cut?
the third pic is the little black thing dont know what its called but the hose thats connected i think goes to the EGR and the other hole should travel to the bottom of the trotle body and spit to the canister but to the left of the little black thing there is a niple where does that go to?
if u guys have pics of 1989 350 TPI and can send me multiple angles, pics of the hoses i just mention for easier reference that would be appreciated send pics to Diablo1986WS6@hotmail.com

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
Fellow TPI owners, I need some help. Can anyone help me with the routing of a few hoses and vacuum lines? Please
. You see, my uncle has worked on engines his whole life and I asked him if he was familiar with the TPI engine. Of course he said yes because of the money I offered for his help. Well after the overhaul, he seems to be completely confused of the routing of the hoses and lines. There are 8 areas of interest.
1. PCV Valve
2. Little pipe (male) on intake manifold
3. upper male outlet on throttle body
4. lower male outlet on throttle body
5. male outlet tube on driverside rear of intake plenum
6. vacuum line from fuel pressure regulator
7. vavuum line from EGR Valve
8. Little tiny male tube that sticks out under throttle body
Thanks, any help would go a long ways.

3. This gets a black rubber hose and carries coolant to PCV valve on passenger side valve cover..
4. This goes to the heater diverter valve.
5. This is the brake booster hose connector.
6. I have never seen this before,sorry
7. Vacuum line from EGR valve goes to the rear connector of the EGR solenoid. You will see it , it is between the coil and the dist.cap. It has 2 holes where 2 plastic hoses plug into. One of which goes the the EGR valve and that would be the rear one.
8. This gets the other plastic hose that runs to the other (front) spot of the EGR solenoid.

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
89RESTO is right on.
#6 goes from the FPR to the intake on the passenger side:
#7 EGR goes into this guy:
#8 You should have a little skinny vacuum line coming from your evap canister, that goes under you're intake, which then splits. One half goes into that little TB male end, and the other goes into one of the male end in the picture above.
I hope I did ok, it's late and I'm getting sleepy.

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
There are 2 sensors that run under TB.
SENSOR 1 - line to EGR
SENSOR 2- line running passed EGR that connects to NIPPLE UNDER TB.
I have SENSOR 1 CONNECTED to EGR.
I am missing line that connects to SENSOR 2. The nipple under TB is capped
NOT SURE WHAT SENSOR THIS IS????

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
The only other devices under the plenum is the iat/mat and egr temp sensor but they don’t use a vacuum signal. I think the t vacuum goes to the ccp.

If you need a egr solenoid Post a ad in the classifieds or buy this one .

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
Referring to the EGR SOLENOID. I don't have a unit with two pipes where the first would go to egr and the socng would connect to the nipple under by the throttle body.
I have an individual wire starting behind by distributor going directly to egr.
There is another connection behind by distributor that is not connected (I am guessing that this is supposed to be connected to something where a vacuum line connects to the nipple under throttle body. (with a T CONNECTIONS LEADING to the canister.
In other picture I see a box (egr solenoid?) with two wheres that go to where I explained.
what setup do you think I have? ill post pictures when I get home
please help

The individual wire is the egr temp sensor. There should be two wire coming from the loom by the distributor for the egr valve.iirc grey and pink/black .

Re: TPI OWNERS, I need a little help please. Hoses and lines issues.
Wanna say thanks for helping out. Green wire connects to EGR temperature switch. GOT IT What is the name/part for burnt gray and black wire so I can replace? Where does it go and what part is the other end pice that connects to burnt piece.
LOOKING ON YOUTUBE AND LOOKS LIKE THESE ARE SUPPOSED TO BE COMBINED ON EGR SILONOID, or is it vehicle specifics. I have 1986 v8
Car failed smog because of EGR function. They are pricing 500-1000$ to fix which I don’t have so if You can help me I will fix it myself
Is there supposed to be anything connected to nipple on EGR? I currently don’t have anything connected to it
*UPDATE so I learned vacuum line is supposed to go on nipple/EGR VALVE?
I RUN THE VACUUME TUBE FROM NIPPLE/EGR VALVE to BURNT Connection (black and grey wire) but what goes in between?

Yes , the vacuum line goes from the bottom of the tb to the solenoid then to the egr.
the egr solenoid connector is a weather pak male connector.
