Help with Card fuel lines and other

[Oddjob]

I think someone has fitted a vacuum fuel tap, maybe the tank was changed for a later design and the old tap didn’t fit. It looks as though to get the tap to work they fitted a vac gauge adapter into the vac screw fitting and used that for the fuel tap. The other pipes look standard. Has the fuel tap got one or two fuel pipe outlets?

I’ve just ordered a new tap 16950-461-771 this has one outlet this should fit on the large hose just not sure what to do with the other two

Looking at the parts list you appear to be missing a part described as an auto fuel cock part number 16970-460-731. This acts like a vacuum operated fuel tap in that it only allows fuel to flow when the engine is running. The brass nozzle is the vacuum take off, your missing the pipe. The other 2 fuel lines connect to this auto fuel cock and a final pipe connects that to the fuel tap.

Post a full pic of the carb bank so we can see if it’s missing.
