Fuel pressure regulator 2000 Hyundai Accent

Hyundai Accent

I need to either adjust or replace the FUEL PRESSURE REGULATOR. Is heir a quick check to fix a faulty regulator or replacement kit or complete FUEL PRESSURE, REGULATOR. How do I go about the procedure?

On a 2000 Hyundai Accent the fuel pressure regulator is located in the fuel pump. So the fuel pump will need to be replaced. I have added the DIY fuel pump replacement procedure below along with corresponding diagrams. The Labor time for replacing the fuel pump is at 0.8 of an hour.

I also went ahead and looked up the Fuel Pump Kit that fits your 2000 Hyundai Accent. Purchase Fuel Pump Kit Now for $22.99
