Hi and thanks for the speedy reply..
Well the first one changed the front sender unit, all put back together, first it was ok then fault returned. Then tank out again, renewed the wiring plug, back together and the same happened again. Tank out again to check/change something else. In all it was in and out 6 times.
Then went to 4 x 4 LR specialist, changed BOTH sender units, renewed and he wiring plug to revert back to how it was from new: all working fine, I collected it drove max 100 yards and on it came again…!!
