What is this in line fuel device ?
This small device (see pictures) is in the fuel line just before the glass bowl sediment water catcher. I am stumped. I pulled the glass off to clean it and check it for any accumulated water or debris. It was clean. It appears to be a float valve with a small flat brass piece hinged at one end. When I push the non hinged end UP it shuts off the fuel flow. Big question, since there is no float attached to the brass rod, what is it ??? From the shallowness of the glass cover, it does not seem a float could ever have been attached
A pure guess would be that it is some sort of a check valve to keep gas in the carb if the T was equipped with some sort of accessory carb. The site glass might be to help set it up or verify that gas was present.
It looks like a fuel pressure regulator. Do you have an electric fuel pump.?? I have a couple different versions of similar regulators ... If you have no fuel pump it is not needed. I believe they are an accy. item from the 40s 50s 60s era.
Did it have a vacuum line attached? Or a port for one? I have considered using a vacuum operated fuel shut-off valve like some motorcycles use.
Donnie Brown may be right. This car is equipped for some reason with a fairly large electric fuel pump along with a Model A carb and intake For the life of me though I do not see what would move the brass arm UP to shut off the fuel
I agree that Donnie is probably right that it is a pressure regulator. From the look of the part, it clearly has a diaphram as part of it's design and likely has a needle valve integral with it to restrict the output flow relative to the pressure of the pump. By pushing up on it, you acted as the diaphram would, and closed off the fuel supply
David, Here are pics of my two different ones I have. The one with the clear bowl is probably like yours, It appears you can not see the name plate on yours, as yours is hidden ...
