For single sender applications:
The sender ends should be
¼” to ¾” away from the top and
bottom of the tank, to allow for the thickness of the tank top and
bottom and any bows in them (see the diagrams). The senders
are calibrated to account for this distance from the bottom of the
tank. The SS sender is cut to the nearest even 2” in length. The
ES sender is cut to the nearest even 1.5” in length, for example,
for a system with a tank height of 11.75”, cut the sender to be
10.5” long, this allows ⁄” at each end when the sender is centered
vertically on the tank. The JS sender is cut to the nearest 1.0” in
length. IMPORTANT: DO NOT cut the 710SS sender shorter than
6”. This sender will not work if it is cut shorter than 6”. DO NOT
cut the 710ES sender shorter than 4½”. This sender will not work if
it is cut less than 4½”. DO NOT cut the 710JS sender shorter than
4”. This sender will not work if it is cut less than 4”.
For double stacked sender applications:
For tall tanks, two stacked 710ES or 710SS senders are used. The
sender ends should be ¼” to ¾” away from the top and bottom of
the tank, to allow for the thickness of the tank top and bottom and
any bows in them (see the diagrams). The senders are calibrated
to account for this distance from the bottom of the tank. In
addition, there needs to be a gap of ⁄” to ⁄” in between the
two senders. Therefore the total length of both senders will be:
tank height -¼”-¼”-⁄”, then rounded down to the nearest 1.5” (ES
sender) or 2” (SS sender) . The top and bottom senders should be
approximately the same length for best results. For example, if the
tank height is 22”, then 22”-¼”-¼”-⁄”= 21 ⁄”, so the total length
