Device for detecting water in fuel
First Claim
1. A sensor device for detecting the presence of water in fuel being pumped from a fuel storage tank by means of a fuel transfer line with a fuel transfer element attached at the end thereof, comprising:
- a tubular member adapted to be placed on a fuel transfer element disposed between a fuel storage tank and a fuel container into which a fuel is to be pumped,said tubular member having an inlet for receiving a portion of the fuel being pumped from said fuel transfer element, an outlet for discharging the portion of fuel conducted through said tubular member, and a transparent portion disposed between said inlet and said outlet; and
water responsive visual indicating means disposed in said transparent portion of said tubular member to contact said portion of fuel conducted through said tubular member and produce a visual signal responsive to contact by water to indicate the presence of water in said portion of fuel passing through said tubular member while said portion of fuel is discharged from said device thru said outlet.

Abstract
A device adapted to be placed between a fuel storage tank and a fuel container into which the fuel is to be pumped, for example on a fuel pump nozzle, for detecting the presence of water in the fuel being pumped. The device has a tubular member with an inlet for receiving a portion of the fuel being pumped, an outlet for discharging the portion of fuel conducted through the tubular member, and a transparent portion disposed between the inlet and outlet. A chemical paste composition containing a water responsive indicator dye is disposed in the transparent portion of the tubular member to contact the portion of fuel conducted through the tubular member and produces a visually noticeable color change indicating the presence of water in the fuel being pumped.

16. The combination of a fuel pump nozzle and a sensor device for detecting the presence of water in fuel being pumped through the nozzle from a fuel storage tank comprising:
-
a fuel pump nozzle connected with a fuel storage tank for pumping fuel from the fuel storage tank into a fuel container; where said device comprises a tubular member on said fuel pump nozzle having an inlet which receives a portion of the fuel being pumped, an outlet which discharges the portion of fuel conducted through said tubular member, and a transparent portion disposed between said inlet and said outlet; and water responsive visual indicating means disposed in said transparent portion of said tubular member to contact said portion of fuel conducted through said tubular member and produce a visual signal responsive to contact by water to indicate the presence of water in said portion of fuel passing through said tubular member while said portion of fuel is discharged from said device thru said outlet and into said fuel container. - View Dependent Claims (17, 18)

19. The combination of a filler neck of a vehicle fuel tank and a sensor device for detecting the presence of water in fuel being pumped into the fuel tank through the filler neck via a fuel pump nozzle inserted into said filler neck comprising;
-
a filler neck connected with a vehicle fuel tank to receive the outlet end of a fuel pump nozzle connected with a fuel storage tank from which fuel is pumped; a tubular member on said filler neck having an inlet positioned relative to said outlet end of said pump nozzle to receive a portion of the fuel being pumped into the fuel tank, an outlet which discharges the portion of fuel conducted through said tubular member back into said filler neck, and a transparent portion disposed between said inlet and said outlet; and water responsive visual indicating means disposed in said transparent portion of said tubular member to contact said portion of fuel conducted through said tubular member and produce a visual signal responsive to contact by water to indicate the presence of water in said portion of fuel passing through said tubular member while said portion of fuel is discharged from said device thru said outlet and into said fuel tank. - View Dependent Claims (20, 21)
