Question: has there been a modification in design of the brake booster line? I have picked up a replacement line...the line resembles the old one, including the white check valve, except that the two accessory ports for the IP and Ignition/ACC system are located outside the firewall closer the vaccuum pump on this "new" line whereas the original line has the two accessory connections right next to the brake line.

Since I really am interested in just changing the white check valve, does anyone know if the brake hose disassembles...the fittings seem really tight and I don't want to break it...Are they glued together?

Thanks
