Another Petcock/Fuel Valve Question

[ridingron]

I'm adding an R&M aux. tank I bought used. Anyone know the height/length of the stand pipe on the petcock/fuel valve?  I would like to know when I'm down to the reserve fuel.  I'll have to cobble something together as the R&M part isn't available.

EDIT: I am referring to an Interstate tank.

Height, unknown. Fuel reserve, known. It's in the service manual, fuel tank, reserve. Which bike, C/CT or CF?

Thanks, just what I needed to know.
