Sandy gave me the past two days off so I started and finished one of my winter projects. Installed a fuel presure gauge. Anybody know what it should show at idle and around 3000 rpm ? (92 lt-1)

Typically specs quoted are 39lb @ idle ;
43 -45 lb @ idle with vac line disconnected and plugged

Thanks for your help, getting 39lb at idle with vac lines connected. there are two vac connections beside the scradervalve, upper and lower, Witch one do I pull and what end do I plug?

The one that goes to the fuel reg; the can thing on the LH end of the fuel rail shown in your pic
Plug the end that goes to the intake
