Yeah with the shifters on ford single rails I have found 4 types 
1  Cortina shifter
2  the long fork
3  the shorter fork 
4  the long fork with the narrow horse shoe.
And what I have found is number 4 is very early, number 2 is around xb to xd and number 3 is xe to xf . 
Found out all this the hard way.

I already have this xf one as it's a very low km box that was driven very carefully,I'm just putting new selector seal and gaskets through it .I'm just worried about the short 1st gear.
Would this mean 1st gear would be a longer shift or a shorter 1st gear shift being 3.47 ?

Thanks for the great info outback jack .il rip out the sender tomorrow and go from there . You answer all my questions.

Thanks outback jack ,with the pump can't I just put a fuel line on the end of the pick up like you said and just use the standard mechanical fuel pump on the bottom of my block ? Also when the resistance is sorted out will I need to calibrate my gauge ?
