I don't see what car your talking about. Is it a T series or a B series? Don't know about a T series but a B, you just don't pull it out of the fire wall. Their put in with no fittings on them. And, it can't be said enough, LABEL, LABEL, LABEL! (With labels that don't fall off). Gee, I wonder how I know that. You'll be sooooo happy you did!
