not building boost during boost leak test

zip tie everything! zip ties are your friend. on my car i even super glue the nipple before i put the vac line over stuff since stuff starts to leak past 35psi where it dont around 25-30.
specifically zip tie the fuel pressure regulator vac lines for safety.

old school trick to backup the zip ties....shoot a little hairspray on the end of the hose and slide over the fitting or vacuum nipple then tie of with a zip tie. when it dries it'll glue the line on with a temporary bond that can be remove with some force, but won't blow off under high boost.
works great on couplers and orings too in a pinch if needed in such an application.
