3 Attempt and fail to pull the regulator out by hand.
4 Use vicegrips wrapped in cloth to twist, wriggle, and pull on the regulator.
5 Curse and swear because it's not coming out and the vice grips are just slipping.
6 Get rid of the cloth and just chew up the regulator casing with the vice grips, with enough force it will pop out (o-rings are a very tight fit).
7 Clean or buy new regulator.
8 Try to push the reg back in by hand, fail and swear some more.
9 Tap it back in with a rubber mallet, socket extension bar, and cloth.
10 Reinstall circlip and vacuum line.
11 Before starting engine jump fuel pump relay with a wire to run the pump and check for leaks.

I recently had the same trouble and did pretty much what you had to fix it. I removed the Fuel rail and cleaned it our thoroughly with thinners and later some wonderful Stove cleaner then some more thinners. I changed the Fuel filter as well, seems to have fixed the problem.
