Fuel Pressure Drop at 3k only?

[355chev]

Would it matter that Im running 95 TBI sending unit with a vortec pump? Also would a fuel pulsator have anything to do with drop off? I am not running one of those.

Cured it with new Dorman sending unit and Quick Fuel Hot Wire Kit.

I dont think pump. pump is not rpm controlled look elsewhere.

IMO the pump either works or it doesnt. I fixed it with new sending unit, dedicated grounds to frame and hot wire kit.
