Abstract: A fuel pump manifold for a fuel delivery system of an automotive internal combustion engine includes a unitary housing with a fluid conduit formed therein. Inlet and outlet ports communicate with the fluid conduit, which are adapted to be connected to the outlet of a fuel pump and a fuel supply line, respectively. The fuel pump manifold further includes a jet pump supply port communicating with the fluid conduit to feed a jet pump of the fuel delivery system. To prevent fuel from draining from the fuel supply line through the manifold, a check valve is disposed within the outlet port. A pressure relief is also disposed within the fuel pump manifold to relieve excessive pressure in the fuel supply line.

Abstract: A liquid level sender device for measuring a level of a liquid in a tank having a first wall and a bottom wall includes a bracket mounted to the first wall of the tank, a first potentiometer mounted on the bracket, a float arm movably connected to the bracket and cooperating with the first potentiometer to generate a first variable resistance which varies according to the position relationship between the bracket and the float arm, a float mounted on the float arm which moves according to the level of the liquid in the tank and moves the float arm accordingly, a second potentiometer mounted on the bracket, and a compensation arm biased against the bottom wall of the tank and movably connected to the bracket, where the compensation arm cooperates with the second potentiometer to generate a second variable resistance which varies according to the position relationship between the bracket and the compensation arm.
