In the early 1970s the factory authorized a recall of all 914s for replacement of the cloth covered upper fuel lines with high pressure rubber covered ones impervious to battery acid. Now you too can duplicate the factory procedure with this high pressure kit including the pre-bent injector elbows and special nonintrusive clamps.
Kit consists of:

1 - b7mmidhose - 9 feet of 7mm id hose for fuel line kit - high pressure hose smooth

14 - r99951205502 - hose clamp 12mm

4 - b043133387 - 914 fuel injector line elbow
