1986 GMC PROPORTIONING VALVE BRAKE PROBLEM

I just replaced the brake proportioning valve in the front of my 1986 GMC Pickup Sierra 1500 2 wheel drive 305 cu in engine, 139K miles Piickup. I had to also replace all the brake lines. After completing the job I went to bleed the brakes and have no fluid at the front passenger caliper. When I take the cap off the master cylinder and press on the brake pedal the fluid in the rear reservoir squirts up. Could I have swapped two of the 3/16" lines? The one going to the master cylinder and the one going to the passenger front caliper. Naturally I didn't make a plumbing schematic first. Any help is appreciated.

Thanks Mike
