fuel tank sending units

[ninab@scoresheet.com (Nina Barton)]

A while back, there was some talk of sending units from Moss being bad.  I
replaced one a year ago on the 71 MGBGT, it failed, so replaced it again,
and it has failed a week later.  Before I talk to the friendly people at
Moss, is there some other problem I may be overlooking here?  Wiring seems
good, temperature gauge works fine, so I don't think I have a problem with
the voltage stabilizer, anything else anyone can think of?  Thanks in
advance,  Nina
