To rehash and old question:

Is the gas gauge sending unit in my 83.5 the same as the sender in the later
model busses. There was a list discussion a few weeks back that quoted a
later Bentley than I have as listing the volts(?) that the sender sends out
when empty is different for the 83.5 - 84 verses the 85-later. (the volts
were the same at full I think) I'm no expert so the difference may be
negligible. My goal is to get the most accurate gauge reading on the fuel
level.

I was thinking that since I have to drop the gasoline tank to replace the
weeping vent lines in the next few weeks I would replace the sender to
accomodate the later model instrument pod I installed--this would (in theory)
match the gauge to the sender. But I see while looking for the part number in
Rocky Mountain Motor Works catalogue the sending unit they list is the same
for 80-88 Vanagons up to ch#24 J 003006. The sender Part # 251 919 051E

So it seems changing the sender is not necessary.
Anyone know about this one? And since RMMW lists only up to 88 what's the
difference after 88?
