Abstract

This fuel pre-heat device includes a tubular section, which is connected at each end to a radiator hose to receive heat from the hose, and a fuel line section which is wrapped around the holder. A housing is provided to enclose the wrapped fuel line, and a pressure regulator is connected to the fuel line to regulate the pressure of fuel entering the engine.

Claims

1. A fuel pre-heat device for use with an engine having a fuel pump, a fuel dispenser and a radiator hose, the device comprising:

(a) a tubular section having opposed ends communicating with the radiator hose,

(b) a fuel line section including opposed end portions and an intermediate coiled portion wrapped around the tubular section, one of said end portions being connected to the fuel pump and the other of said end portions being operatively connected to the fuel dispenser,

(c) a housing for the coiled portion of the fuel line including a tubular body having annular end recesses and opposed covers attached within the end recesses, each of said covers having an opening adapted to receive one end of the tubular section and an opening adapted to receive one end portion of the fuel line section, and

(d) the fuel line section coiled portion including at least two turns and the ends being disposed in cross-over relation to each other.

2. A fuel pre-heat device as defined in claim 1, in which:

(e) the housing covers are circular discs and the opening for the tubular section and the fuel line section are offset from the center thereof.

3. A fuel pre-heat device as defined in claim 2, in which:

(f) the housing body is spaced from the fuel line section coiled portion and the end portions of said section.

4. A fuel pre-heat device as defined in claim 1 in which:

(e) the covers are adhesively attached within the end recesses.

5. A fuel pre-heat device as defined in claim 1 in which:

(e) a pressure regulator is connected between the fuel line section and the fuel dispenser.
