got a tial 38mm WG a while ago...but now i forgot what psi springs did i order....
is there anyway i can check?...like unbolt the top and see what color spring?...

 

Hook it up and see.

 

Yup, you can unbolt the Cap and see what color the spring is. call Tial direct and ask them. If you look at your shipping invoice it usually says what spring they included. Or just say ---- it and throw it on

is it hard to put it back once i took it out?

 

Nope..
