K so last saturday I put in my fass hpfp 95 series (95-1003) and I dont have any problems with it but when i was installing it I noticed that there was a little screw with an allen head on the top of the pump? is this a fuel pressure adjuster screw? i have no idea what it is.......

any info would be much appreciated

 

Pressure tap.......should have a "G" next to it.......

OR do you have the new ADJ regulator pump?

 

I'm think its the pressure tap? cause if I had the adj regulator pump it's tell me how to adjust the pressure in the instructions? wouldn' t it? and also what does the pressure tap do?

 

You can directly sample the fuel pressure the FASS is supplying from this tap.
