Volvo 20973777 is the fuel pressure sensor with a steel threaded body, hex and a three pin plug. It is used on Volvo excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Engine low on power or in derate
A fuel pressure sensor that reads wrong makes the engine controller cut power. Check the fault codes for a fuel pressure fault first.
Hard starting
With no valid fuel pressure signal the engine may crank for a long time or not start. A new sensor restores the signal.
Fitting tips
Work clean, fit with the engine off and the fuel system at rest, tighten to the original torque and check for leaks.
