I ordered a, no moving parts" replacement sender, direct, from Livorsi. I provided the depth of the gas tank to them while on the phone ordering. Livorsi had the unit cut to size when it arrived exactly THREE Days Later. The unit I ordered was a two wire, direct replacement. What an improvement---once I set the "full" properly (the empty was pre-set by Livorsi since they cut the probe to proper length), it has been EXCELLENT. No bounce or jitter and spot on.
Highly recommended and costs less than the float type replacement Allison sells.
