Check THIS THREAD... This is what a few of us here have installed recently. I can personally recommend this highly.

I no longer monitor the forum, please either post your question or create a support ticket.
I just use a cheapo mechanical gauge with hose propped up on cowl to verify then remove. Not as good, but close and movable.

I bought one this morning at the parts store, wonder how accurate it is.Originally Posted by Bruce Melton
It reads 61 psi. I have a Kenne Bell boost-a-pump and the pressure goes to 63 psi at maximum setting.

What a bunch of has have found is that our fuel pressure is not a static pressure. Mine ranges from ~53PSI at 0 kPa vacuum to ~62PSI at 80+ vacuum.
This is a pretty wide variance!!! As a result of logging the fuel pressure I've changed the slope angle of the IFR table, which in turn has brought the VE table back inline to what I consider more reasonable and realistic values.
