4B•10 Fuel and exhaust systems - K-Jetronic fuel injection - 8 valve engines 20 Fuel filter - removal and refitting 2 Refer to Chapter 1, Section 33 19.1a Fuel pump and associated components 21 Fuel accumulator - removal and refitting 2 Removal 1 The fuel accumulator is mounted on the outboard side of the fuel pump reservoir on the underside of the vehicle at the rear, just forward of the fuel tank (see illustration). 2 Disconnect the battery earth lead. 3 Raise the vehicle at the rear and support it on axle stands (see “Jacking and vehicle support”). 21.1 Fuel accumulator unit location 4 Disconnect the fuel pipes from their connections at the front end of the regulator. 5 Undo the clamp bolt and withdraw the accumulator. Refitting 6 Refit in the reverse order to removal. Check that the fuel line connections are clean before refitting. On completion, check for fuel leaks with the engine running. 22 Fuel tank and associated components - removal and refitting 3 The fuel tank and associated components can be removed and refitted in the same manner as described for carburettor models in Part A of this Chapter. To test the breather valve, blow through the hose (dotted arrow - see illustration 7.3 in Part A of this Chapter) and push the lever in to see if the airflow opens then shuts off as the lever is released. If defective, renew the valve. 23 Inlet manifold - removal and refitting 3 Note: Access to many of the fastenings and fittings of the manifold, on the bulkhead side in particular, is not good due to the close proximity of adjacent components. It may therefore be found necessary to at least partially disconnect and remove the 1081 VW Golf & Jetta 19.1b Fuel pump viewed from rear 19.4 Disconnecting wiring connector from fuel pump engine/gearbox unit to gain access to certain items and allow clearance for manifold removal. Modification: As from September 1984, components associated with the inlet manifold were modified (see illustration). All work procedures remain as follows for engines manufactured before that date (see illustration). Removal 1 Disconnect the battery earth lead and decompress the fuel system. 2 Disconnect the accelerator cable from the throttle valve and support/adjuster bracket on the manifold. 3 Disconnect the wiring connector and the vacuum hose from the auxiliary air valve. 4 Disconnect the wiring and detach the warm-up valve. 5 Undo the hose clips and detach the vacuum hose from the connection on the end of the manifold (left side) and the rear side of the throttle valve housing (see illustration). 6 Disconnect the vacuum hoses from the front of the throttle housing, noting their connections. 7 Disconnect the injectors and hoses from the cylinder head, release them from the location clips and fold them back out of the way. 8 Unclip and detach the inlet ducting from the throttle housing. 9 Remove the bolts and disconnect the support bracket from the accelerator cable support/adjuster bracket and from the cam cover.
