I recently had the supercharger off and now back together and driving good till the other day I threw a code on my car is said it was running lean Bank 1. do any of u guys know on how to fix it?

Probably a vacuum leak. Check all the vacuum lines.

My favorite way is to use carb clean on vac lines but i cannot stress enough to do this very carefully with a hot engine. When you spray the carb clean on a cracked vac line or leak the engine will idle higher than normal.

I found one that might be the problem it the T that goes in the fuel regulator so I rapped it with duct tape for now till I can get a new one. hopefully that's the problem. thanks.

The t's are a dealer-only part if you want the OE style, otherwise you can buy the right size hose and use the little plastic T's that come in a Dorman HELP kit at your local parts store.

I robbed about 6 t fitting at the junkyard over the summer, because mine split apart. Must be common for them to split huh?

I ended up getting the dealer part for that because of time,, i think it was around 45, next time though I plan to make something that will last a bit longer and be a bit tougher.
