Q's - Check valves and miscellaneous bits
 

I have worked out all of the fittings I need to plumb my turbo, but what other small bits will I need?
I'm thinking about things like check valves for vacuum systems. Which systems needs them (if any) how to spec, where to buy, etc.?

I have combed the FAQ, but I am sure there are little things which are "assumed". Help with any parts along those lines would be greatly appreciated. BTW, my car is a 1997 w/ 1999 engine (VICS).

Thanks!

I didnt use any check-valves in my setup and don't know of anyone else that has.
