Help with a Stealth High Pressure Oil Pump with a 4 line outlet

[Bigdog]

G'day guys its been a long time since i had to ask for your Help , as my truck has been running fine , but it has started to do some strange things in the last few days and one of them is to do a service on the Stealth hpop . all i am after is info and where i can get replacement o'rings and maybe other stuff to stop it leaking and bring the idle Psi back up to 600psi not 350psi
Or does anyone know a shop that i can talk to. Thanks

You probably have tried this already, but did you do a Google search? I think Stealth is belly-up, but there is a diesel shop in Missouri (Diesel Performance Plus? I think?) That still had them listed on their website.
