Ok i am probly going to sound a lil stupid but here goes ive got a blox fuel pressure reg and the vaccume line goes to some thing on the fire wall and that cylendrical plastic somthing or other what is it and can i chunk it along with the one next to it in the scrap bin with my power steering and ac and cruisecontrol any how any advice would be good i got a habit of experimenting and f***in stuff up thanks

 

I think you're talking about the purge control solenoid. If you dump that and your charcoal canister, you'll have fuel vapors leaking into the passenger cabin. It smells like ***. Not something you'd want to do on a street car.

The "one next to it" if I remember is the firewall mounted MAP sensor. Be pretty funny if you try to get rid of that.

Might help to know what kind of car you have...

 

91 teg with a b18a1
and is that the proper vacume routing for the f.p.r. and if it helps the two cylenders are black plastic and about 2in tall 1 inc wide
