Ok guys, I have a 88 Camaro with a 350 TPI that i just bought off a guy. Its not the original motor and whoever put the current engine in did not know what the hell they where doing, They have the vacuum lines rigged up with bolts and what not and there is a leak some where and it has the car idling crazy and sometimes even stalls.... My question is, could it be possible to just run new vacuum lines all together? because whatever he did has a leak some where that is rendering my car almost useless, and if this is possible is it a hard task to complete and also is it expensive??......

Please any feedback will be greatly appreciated because I want to make this my everyday car before my little Toyota dies on me lol. Besides the vacuum leak the motor runs extremely strong...... HELP!!!!!!

 

it should be easy as long as you have a diagram as to where each one goes. and get all the right sizes. for the map sensor i used 1/4 inch fuel line as it is stiffer. shouldent be that much for 3 feet of each size. maybe like 4 sizes.

 

Where would you suggest getting a diagram? Also where did you get the lines from and how long did it take you?

 

Get an official shop manual.. that will have everything you need. You can find them on Ebay all the time in decent used condition.

 

Ok, Im looking on eBay now and it came up with results for a gm service manual and a gm service manual supplement, do you or anybody else know the difference between the two?

 

Should be pretty simple... there's not all that many to begin with.

Seems like there's a thread where somebody had been collecting vacuum diagrams somewhere on this site... the FAQ forum maybe? might be worth looking for. Maybe do a search on some mysterious inscrutable word combination you'd never suspect, like "vacuum diagram", and see what comes up.

You can get the line materials at ANY parts store, even AZ and advance and such.

 

Vacuum lines are not to bad to replace. I've ordered some from jegs and bought a few rubber lines from local hardware store.

If your car is still TPI here are the diagrams.

Your vac diagram should be listed on the underside of the hood also.
