I have a 305 tpi 88 iroc z and the vaccum lines are all rotted and some are not where they should be...i called chevy dealers and i got the chiltons but i still cant find it...please help with any info or links to a diagram or blueprint! Thanks!

 

There's not a sticker under hood??

 

Nope...its a reconstructed front end so it may not be original.

 

Aside from staring and comparing with another car like yours, you may try to order a VECI label from a Chevy dealer, but chanches for them to be able to get them are slim due to the age of the car. A Factory Service manual, if you can still find one, will most likely have a picture of the label.

 

what do you need to find, pretty much everything? the chiltons manual has everything shown, there isnt that much on the tpi. egr valve, fuel pressure regulater, and the hvac use the two rear ports. egr and fpr use a tee. evap canister and cruise control go up at the front or might be tee'd. brake booster uses the lower on the driver side, pcv uses upper (or vice versa), and the breather goes in at the tb. there shouldnt be anything else

 

found it...now the fun part...putting it all together

 

ok ,again buy a HELM inc factory manual,im telling you guys,it removes ALL questions and is well worth the price
