VDO's ALAS 12/24V adjustable swing arm senders are engineered for severe-duty use. The sender main body features a plated steel construction to help eliminate damage caused by fuel slosh. These units contain an SAE standard five-hole metal mounting flange and body components, which can be adjusted from 6 in. to 23 in. tank depth, and are adaptable to right or left hand swing arm. For maximum durability, wiper and thick film resistor are shielded (from fuel slosh) and float arm stops to ensure wiper remains in contact with resistor board when tank is full or low.
