Not sure if this helps you, but on my 30 psi model, the hexagonal portion right above the threads was stamped '2 BAR' which is ~30psi. Maybe yours has a similar marking?

These are the markings of the 80 psi fuel sender from VDO (1/8-27NPTF, or VDO#918-360-003) - they are roughly $35 on EBay.

150psi unit is marked '0-10bar'.
I purchased mine through Jegs with a part number of 360-004.
The packaging has an additional number 'V1521001040D' - not sure what this is.
