A hydraulic oil cooler is provided with steps for allowing a person to access a rear portion of a tank truck. The hydraulic oil cooler includes a housing having a first side, a second side opposite the first side, and a front side extending between the first side and the second side. The housing is configured for attachment to a frame rail of the tank truck. The hydraulic oil cooler further includes at least a bottom step and an intermediate step disposed on the housing with the bottom step and the intermediate step extending outwardly from the front side of the housing. The width of the bottom step and the intermediate step is between about 254 millimeters (10 inches) and about 609.6 millimeters (24 inches). The steps are made of a slip-resistant and self-cleaning material and have a predetermined surface pattern for increasing the amount of gripping and traction of the steps.

A system for loading fry bulk materials into a tank trailer includes a blower assembly mounted on a tank truck that is in pneumatic communication with the interior of a tank of the tank trailer through at least one conduit. The blower assembly includes a blower and a blower filter in pneumatic communication with the blower through a suction line. The blower assembly further includes a vacuum gauge for monitoring the vacuum pressure of the airflow between the blower filter and the blower and an optional check valve for passing the airflow from the ambient atmosphere in the event that the vacuum pressure of the airflow exceeds a predetermined maximum vacuum pressure for safe operation of the blower. The predetermined maximum vacuum pressure may be no more than about five inches of mercury vacuum pressure (5 in-Hg; 2.46 psi). An operating vacuum pressure of the blower may be between about seventeen inches of mercury (17 in-Hg; 8.35 psi) and about five inches of mercury (5 in-Hg; 2.46 psi).
