one last thing without the air dam they tend to get hot

thanks for the info, I was just trying to get an idea about parts, so I wouldn't have to pull the plenum any more then i have to. I already replaced the air dam so hopefully no problems there. But what about the vacuum pump? I know it isn't coming on, hopefully it is just the inline fuse from the battery I read about but if not does someone have the part # of the one from the GM truck that uses the same one? I work at a college and will be using the automotive shop while we are on break so I hoped to get all the parts I need before I started. The only part I'm really worried about is the vacuum lines under the plenum and the pump.

There was one from I think a Kodiak truck and another one from a Jetta that worked I think. Ive seen the PNs before here and didnt wriote them down.

Someone will pipe in with them, be patient. THese guys have all the answers.

it's a little hard to totally diagnose the vacuum leak with out pulling the plenum first. you might have one leak or ten. i know what your trying to do, you have shop space for XXX amount of time. if that's the case you'd better have everything (parts) on hand, whether you need them or not .

So would the standard vacuum hose rebuild kit from white racing take care of everything under the plenum? Or is there a better solution for these lines? The leak sounds like it is coming from the back of the intake. I guess I will just get it looking and running good for now and then next year look into headers and getting the plenum and injector hosing porting and refinished. I would also like to get the shocks rebuilt and do some suspension stiffening. Thanks for the input so far guys. When i get it back from the paint shop I'll post some pics.

the leak could also be comming from the pvc hose thats in the back .it has a tendancy to rot if its the factory piece . you could get it from curt 200 or get creativce and make your own for a lot less . all depends on what way you want to go . vac lines are easily made by buying buck line and using a hair dryer to form them to match the originals. on the corvette action center is a good thread on the pump . it has a tendancy to corood inside .but it could be the fuse also . the pump if you need one is about 125 for the kodiak truck.good luck

I don't mind making my own vacuum lines. Where is a good place to get the lines and fittings and such. Is there a thread anywhere showing how to do it?
