Fuel leak from top of gear pump head

[SquareOne]

Alrighttyy, so here's the unfortunate update.....ran the leak down test, got the fuel press up to 29k, shut it down, and lost right at 4k psi in one minute (held solid at 24.5psi - not that it matters). Looked at the pump head and could see fuel seeping from the torx, down the side, and pooling at the head gasket. I think it's safe to say where it's loosing pressure...

Now the fun part, have called a few different places trying to get a new head to no avail. Waiting on responses now. If any of you have some info on obtaining the fuel pump head (new) for a cm2350, please let me know.

**Not sure what that torx plug holds down, but whatever it is apparently isn't happy. I rember reading a post from Mr. Hagg mentioning the relief valve in the head. Supposedly once they've failed, the head needs to be replaced. Is this potentially what it is?
