Walbro 392 lift pump

Is anyone using a Walbro 392 lift pump? Glacier Diesel sells a kit that I have heard good news about but I would like to know how much pressure this pump produces, or how much more than the stock LP.

These pumps are capable of running 130psi, GDP sets them to run at about 20psi for the VP44 trucks. That is more than adequate, You really don't want too much pressure in a VP44 anyways. They run best at around 12psi WOT.
