Good To Know

Q: How does this fuel primer pump work? A: It uses a hand-operated plunger to draw fuel from the tank and push it through the filter and injection pump, removing air pockets so the engine can start.

Q: Is the 105-2508 the same as the original Caterpillar part? A: This replacement is designed to match the fit and function of the OEM 105-2508, but it is not an original Caterpillar product.
