Re you reffering to the high pressure side or low pressure?
High press use EFI DVTs and ramp rail pressure up to 160 mPa.
And log rail pressure with scan tool.
Low press you would need a lift pump and then check at the port on the front by the alternator or T off the fuel hose somewhere as close to the cp3 as possible
On a lb7
A 1/4" or 3/8 double barb fitting ( cant remember the hose size )
a chunk of hose
a barb fitting by 1/4" female npt to put a gauge onto
hose clamps
Pull the brass fitting off and hook up to the hose.
