Review on 🔧 Enhanced Fuel Pump Module - Delphi FG0331 by Kuldip Roberts

Received codes P0171 and P0174 (lean on bank 1 and bank 2) Long term fuel trims were 16-25. Immediately checked the fuel pressure and found a fault. The car ran at 20psi to spec. The car had slight bumps at idle and a slight hesitation when accelerating. No surprises so far - installed on a 2003 Hummer h2. Aside from the struggle with removing the fuel tank, installing the new pump was easy. I used to only get 32psi at idle and 27psi on the gas when I slammed on the gas - now the Hummer is 54psi at idle and 60 on the gas. The long-term fuel adjustment is again close to zero. FYI - the pump pictured has a "sock" showing how it comes out of the bottom of the pump housing - this is not present on the new pump I received - all the fuel pickups are in the main housing. . The item arrived in a 'Delphi' box marked 'Made in Mexico'.
