fuel gauge

I installed a new fuel pump and sending unit. A full tank of gas, seldom hits 3/4 on the gauge? Is there a way to correct this? And the gauge needle moves quite a bit around turns, could I place a resistor in line? Thanks

What year XJ?

I just took the gas tank out of my XJ last night (prepping for welding up the rust holes in the floor pan, then cleaning up and sealing the rest of the floorpan).

I plan on playing with the gauge level, I'll let you know what I find out. I have a '95 XJ BTW.

The little float its slide pot, in the gas tank, usually has a little screw pot to trim the resistance and adjust it a bit.

Bend the float rod a little.

Its a 92 4.0. I can bend the rod, that is easy, didnt know if its going to screw anything up.....
