Fuel Sending Unit

Q: Fuel Sending Unit

I’m in need of a two tube fuel sending unit for my 1968 Firebird 400. Does anyone have a used unit for rebuild ? Suggestions for locating a unit ? What was the original part number ?

A: The original part number for the 400 Firebird Fuel Sending Unit was…

6427857 Gauge, Fuel Tank Unit (Sending Unit)

1967-1968 F/8 w/A.C. and 1967-1968 F/8 “400”

This is from a 1969 Pontiac Parts Book.

Big diff. between this and those being sold as replacement units is the Vapor Return tube.
