One Fuel Transfer Pump to fit CAT 3406B (reference number 3406C). It delivers fuel from the tank to the engine. A direct replacement for the original part on these models. Sold individually.
I just installed it so the longevity is still out. It arrived quickly along with the o-ring for sealing it to the injection pump. The output fuel pressure it what caterpillar recommends. The price point is good.
