What I actually need to know is if anyone has any practical, good ideas for a non-factory intake duct setup. I do not have the snorkel that goes to the throttle body (prev owner sold it to a kid with a Blazer), and I don't want to run this thing up the road without an air filter. So what can I do without buying another intake duct?

Also, I'm trying to figure out which one of these fuel lines going to the intake manifold is the pressure hose. They look exactly the same on my car, running side by side. Lower portions of the hoses look to have been replaced before, but the upper (engine) ends look factory. Just want to know which line to tap into for an inline fuel pump.

 

You can use PVC pipe and a cone filter Just duct tape everything together. so there are no leaks

 

OR you could use pvc glue and glue it all together.

 

I only paid 15 bucks for a new intake duct from GM

 

Only 15 bucks? Wow. If that's the case, I might as well go that route. I may look into the cone filter idea as well, if I can rig something up without tape. Whatever's cheaper with this particular car. With the shape it's in, it's not worth putting too much money into...just want to get it driving and sell it so I have more money for my '84

 

I got it from gmpartsdirect.com.

I jsut called the chevy dealer and asked for a price and part number. Then went to there site and orderd it.

 

Thanks for the info, I'll have to call the dealer in town and get that info. Thanks again

 

The smaller dia. line is the pressure line the return line is always the bigger dia. Also if you dont think you can tell the dia or for some odd reason the are the same if someone did a bad job of replacing them then locate the inline filter and follow that. The filter is near the rear axle ... in front of it. The line wioth the filter in it is the pressure line
