Car chockes and Loose power on uphill

[fixkick]

this is true.
i have this portable fuel gauge, 100% electric
i connect it and drive car,
up hill if the pressure drops, on 16v, FPR bad. (let me explain, 16v, up hill vacuum falls very low, the FPR actually raises fuel pressure now. )
In fact it raises pressure to near key on, no start pressure, see my FPR page for the real chart on this.
on 8v,16v filter packed. (its a 60k service point, so should be good on serviced cars)
on 8v/16, above ok, the pump is bad, no pump lasts engine life. 300k +
the pump has many failure modes, even rusted through PUMP rack.
pump has a motor that one commutator segment is dead, super common this. now weak pump.
pump impeller damaged, pump bearings shot. or ? other physical damage , on any turning object.
hoses here, leak.
low 12vdc at pump can be pump not sucking 4amps but 12 or more, its bad.
pump sock filter packed, or rust back up in pump.
it is super nice to have a electric fuel pressure gauge, Id like to have a bluetooth one, not that be , SUPER COOL.

UPDATE#2:
After couple of days that I thought that the problem solved - it returns back.
I got a decision to change the fuel pump...
The issue was that the fuel dump somehow dismounted from its place in the fuel tank and it did not let it to work correctly.
I replaced it anyway - and now all works fine!
