1998 175HP Ficht Fuel Pump Problem & questions

I was unable to get full RPMs and the motor was stumbling very badly at idle.

 

When continuously pumping the fuel bulb the problems go away.

I checked the low pressure lift pump and one of the gaskets seems ripped / torn, have a rebuild kit on order to repair that.

Also checked the high pressure pump and getting right at about 25 PSI.

But should the PSI drop back down to zero after pump is finished? (at startup see video)

Page 3-5 beginning in Step 5 of your manual describes the fuel pressure regulator and has test points.

Thank you, the port on my particular engine is located at the front of the motor on the very top of the whole fuel unit.  I do not have any shroeder valves attached to the fuel rail on the back side of the engine. 

There is a brass fitting right where the shroeder valve shows being attached from exploded view, and after a bit of searching right now i found this fuel regulator repair kit.  https://www.marineengine.com/newparts/part_search.php?part_num=438816

So have answered my own question.  Will inspect it and see if its at fault.
