Product questions
How can I confirm that Dorman 285-5500 fits my Mack E7?
Dorman lists this mechanical transfer pump for specified Mack applications, not every E7 configuration. Provide the vehicle VIN, engine serial number and existing pump number so the application can be checked before ordering.
What connections and mounting features does the 285-5500 pump have?
Dorman specifies male connections with flare fittings, a 10 mm inlet outside diameter, a 7.3 mm outlet diameter and two mounting holes. Compare the connections and mounting arrangement with the existing pump before ordering.

Dorman lists a maximum pressure of 85 psi for the 285-5500. This is a pump rating, not a confirmed operating-pressure specification for every engine configuration.
