fuel sender resistance range

[Crosshead]

I'm installing an aux fuel tank.I plumbed in a 6-way valve,which will also let me swicth between tanks and also read fuel levels in each.My main tank right now is half full and is reading about 110ohms of resistance.I thinking that this sender must be in the range of 240ohms/empty-33ohms/full.Is anybody out there that knows for sure.Thanks Mike.........

leme do some digging for ya today....i want to say the range was 20-160 but i may be confusing it with another vehicle........Marc

15 ohms on empty 160 ohms on full is the spec....give or take about 15% due to resistance building up in the sender over time......Marc

I believe you, but all I could find was 240-33.I either make work or wire it to the gage that came with the sending unit.Thanks for the info.Mike........

the 240-33 sending unit will work....it will never read completely empty though...although it should be close when you are way down.....but above a half tank you will have more than it shows...and less than half a tank you will have less than it shows........and it will read over full till about 3/4 tank.......Marc

Yea, Marc it willnot read down all the way to zero,but very close.At 1/4,1/2,3/4 it's almost right-on,at full it pegs the gage alittle early,but I can live with it.Mike.
