Tii Kugelfisher fuel injection pump o-rings, set of 4.  These are the 4 o-rings that install around the suction valve caps along the top center of the injection pump.  When these get old and cracked, they leak fuel and could be dangerous.  These are a perfect aftermarket replacement, made of Buna-N (Nitrile) for long lasting performance.
