Are you adding an aftermarket regulator or shim the stock one?

If you are looking to just shim the FPR, you can always refer to Steve Baz's site, if you don't already have it under your favorites. It is:

I have only seen the BB deal. I have 'heard' of other methods, but have not seen them.

That looks like good advice to me. I haven't every shimmed a stock regulator before but I took apart mine once to clean it. It wasn't too hard to do.

I could help you out if installing an aftermarket one in the future.

Guys I don't know if this will help you or not, but I used a 4x40 stainless steel cap headed screw. To do this you need to pull the fuel line, and kind of bend it out of the way. Then you need to remove the two screws holding the block on. Be careful when pulling it as there is a spring inside. You should buy a couple of these screws and grind the heads down, grind one down to 0.650, and the other one down to about 0.700 . If you don't have vernier calipers you can use a Nickel for reference, as a Nickel is 0.650 thick. All you need to do now is place the screw into the spring with the head of the screw fitting into the recepticle for the spring, this shims the spring the easy way. Then reinstall the block and fuel line. You should check your fuel pressure at this point. I just used my compression tester gauge, by placing a barbed fitting into the gauge where the hose connects, then I hose clamped a 3 foot section of fuel line onto the drain at the back of the fuel bowl. Then just turn the key to the ON position and the pump will run for about 15 seconds and you now have your pressure reading. On my truck the 0.650 thickness netted me 68 psi so I went no further, I was satisfied as most will tell you 62-70 psi is optimal anyway. I don't have any pictures of this guys so sorry for that but I hope this helps. By the way I now have a regulated fuel return kit in place. Gene :mafia
