walbro PSI fall off

i need few fast/correct anwser's

i installed the walbro and when i prime it the fuel psi falls from 45 to like 12 really fast......... is that normal ?

i have the corrigated hose and such and it has 2 clamps on the top and the pump was one tight so i only used one clamp

when motor is running or under boost the fuel PSI stays vary steady? 46 at idle

this is a v6 but same should apply

wht do you mean by prime? if you open the shrader valve it will drop.
