Bosch KE-Jet System Pressure

On the Bosch KE-jet systems¬†you will connect one leg of the “T” to the fitting on the fuel distributor that supplies the cold start valve (this is the one that the valve will turn off). The other leg of the “T” will connect to a test port located in the lower half of the fuel distributor. This port can be identified by a 8 x 1.25 mm plug with a 12 mm hex head. With the valve open and the fuel pump running you will read system pressure. This is usually 5.4 to 5.6 bar on cars with a single fuel pump, 6.2 to 6.6 bar on cars with dual fuel pumps.
