If you’re like most VW mechanics, you’ve broken into many rebuild kits to steal just the accelerator pump Diaphragm for a repair. Why buy the whole kit, when you can have a couple of spare units in your inventory? Fits almost every stock Solex, like the 28PICT, 30 PICT 1, 30 PICT-2, 30/31 PICT, and 34 PICT3. Does NOT fit the Kadron Solex used in dual carb applications. Sold each.
