Pre-filter for fuel module

摘要

A pre-filter for a fuel pump in a fuel module which includes a housing having a first portion and a second portion that form a channel when the portions are connected together. There is a first port and a second port integrally formed as part of the second portion, and the channel allows for fuel flow between a valve, such as a thermostatic valve in fluid communication with the first port, and a fuel pump in fluid communication with the second port. Both the valve and the pump are connected to the pre-filter. A first portion of the housing includes a mesh, and a second portion of the housing also includes a mesh, which allow for fuel disposed in a reservoir to flow through each mesh and into the second port, providing additional fuel flow to supplement the fuel flow from the thermostatic valve.
