you can get a new fat line, like 3 inches long, then take the new vac line from the evap solenoid., and push it inside the fat line.

this is how i fixed my fat line when it cracked on me. fat hose to normal vac line to the hard line. on a sc car, the evap lives on the rear of the engine on that bracket you posted a few weeks back.

The rpms only go up when I spray right where the TB meets the SC. I replaced the gasket with the brand new one and it still did it. I'm kind of thinking that it just soaks into the gasket and then gets in there? I mean, it's a brand new gasket, and torqued down to specs and then some. I could go all around the gasket with some Blue RTV i have if you think that's neccesary. Also, I used MAF cleaner instead of Carb cleaner. I didn't have any carb cleaner so I figured MAF would be okay to use since it's less aggressive. My EVAP is still at the front of the car, same place it was at before the swap.

also here is the new youtube vid. took a while to upload. Thanks for all the help guys, I really appreciate it.
