As this is a non stock application, a few questions are in order.
What pedal setup do you have? Are you getting a decent stroke on the cylinder?
Is the pedal push rod set up so you get a minimum of wasted stroke before the piston closes off the recuperation port? Is the recup. port open at rest? Do you have a good return spring on the pedal?

I find it difficult to bleed by just pumping. I have used both pressure type bleeders and a vacuum system before now, and they both got the job done. The pressure type is better, though, just a little more finicky to set up.
