Good To Know

Q: Is this overflow pipe the same for gear and hydrostatic transmissions? A: Yes, the fuel return line is independent of the transmission type, so it fits DT, GST, HST, and HSTC variants of the L4330.

Q: Does this pipe come with mounting brackets or clamps? A: This listing is for the overflow pipe itself; reuse your existing clamps or purchase new ones separately if needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
