Fuel pressure


1999 Ford Ranger XLT 2x4, AOD, 4.0 L engine, 107K miles. VIN X engine code.

This truck has 65 PSI fuel pressure, it's not a flex fuel engine. Some books indicate the fuel pressure should be about 35 PSI some indicate 58/72 +/-

The scanner is showing left and right bank rich and continues to trip the engine lamp. I replaced the fuel pressure regulator. Ford calls it a fuel dampner. Try to find this part number (F87E-9F775 CB) the fuel pressure is still 65 PSI

All part listings for the fuel pressure regulators are incorrect.

Can you give me some direction?


Do you
have the same problem?
