Alright, i have installed on my Cruiser a long range fuel tank. My question is, i know my fuel gauge is off, but should it be? and is there anything i can do to recalibrate it?

Fuel level senders are just potentiometers with floats on the end of the 'knob'. Good luck if you want to know exact gallons at any given fill level. Very few senders & gauges are that finely calibrated.
OTH, you can bend the wire arm on the sender so that when empty it reads empty. It is possible that you could get the sender to read correctly at both extremes, but that would take a bit more work.
For me, I'm not so concerned with a full tank reading correctly as I am with an empty tank reading correctly. Ideally I'd like it to read empty when there are 1-2 gallons left in the tank.

I believe some places sell an extender arm for the fuel level sender to give you an accurate reading on a long range fuel take. I think MAF sells them.
MY LR tank fuel sender arm has a bit of wire extending the arm so it touches the bottom of the tank on empty.
So the standard arm was cut in the middle, and then the length of wire brazed in to lengthen it. Can't help with the length, do it by trial and error.
