In new fuel transfer pumps, 7E2464 Valve (1) is held in position by 7E4656 Retainer (4). See Illustration 2. This is possible because new 1W1698 Housings are slightly modified in the area where the retainer is installed. 2S8398 Spring (2) can be installed in place of retainer (4) when repairing the new fuel transfer pumps.
