AO fuel sending unit length

[j_boucher]

Good morning currently working through my punch list and I was curious if anyone knows the stock tube length for the fuel sender . Mine works fine till about 1/2 tank then starts to stick sometimes . Or know a good way to keep them from sticking .
Thanks in advance.... EDIT I believe I found it 15 inches

yea somewhere near the tank height. Those might be purely inductive units. if they have a float, it is inside the aluminum tube assembly. made by isspro...

I purchased this unit and it has worked well.
