In the meantime I emailed three tank manufacturers. All three recommeded a
cork-on-a-tube type made by WEMA of Florida.

Has anyone had positive experience with fuel senders?
They seem to be notoriously inaccurate.

I've seen the type with the vertical cork, the hinged cork and the one
that
has a tube within a tube (air pressure or and electric sensor?)

I'll be cutting into an aluminium diesel fuel tank to install.
