Fuel pump module having a fuel filter water drain
First Claim
1. A vehicle fuel tank assembly comprising:
- a fuel tank having an interior;
a fuel pump module being at least partially disposed within the interior of the fuel tank, the fuel pump module comprising;
an inlet;
an outlet downstream of the inlet;
a fuel pump downstream of the inlet and upstream of the outlet;
a fuel filter chamber downstream of the fuel pump;
a fuel filter disposed within the fuel filter chamber and having an upstream side and a downstream side; and
a filter drain conduit in fluid communication with the fuel filter chamber substantially at the upstream side of the fuel filter and extending externally of the fuel pump module and fuel tank.

Abstract
A fuel pump module adapted for mounting within a fuel tank and including an inlet, an outlet downstream of the inlet, and a fuel pump downstream of the inlet and upstream of the outlet. A fuel filter chamber is downstream of the fuel pump and includes a fuel filter disposed therein having an upstream side and a downstream side. A filter drain conduit is in fluid communication with the fuel filter chamber at the upstream side of the fuel filter and extends externally of the fuel pump module and fuel tank. The filter drain conduit may be in fluid communication with the filter chamber substantially at a lower portion of the fuel filter, and may include a valve located externally of the fuel tank. A heating device may be provided in the fuel filter and a recirculation device may be provided in the drain conduit.
