Newbie? whats the best wvo tank level sending unit?

[biged4x4]

Hello all,
Thanks for all the good info on here, it has been very beneficial.
Background: 2000 F350 7.3L in the process of converting to wvo.
I'm sure most will recognize that the way I designed my system is 99% the same as the check valve system design that has been published on here in the past. So credit for my system goes to FN74's check valve design, I think that is where I read about it and incorperated his ideas, anyways to who ever designed it/developed it, thank you!
Nuts and bolts of the conversion.
90 gallon aluminum transfer tank/tool box combo, artic fox pick up, TIH 3/8, FASS HPFP(1004 model), Davco 12v heated 382 filter, 30 plate FPHE from Duda diesel (12 inch version), aluminum mantifold with check valves on each side diesel/wvo enter through checkvalves from each side and lines leaving mantifold into front of each head. Lines off the back of the head T into a purge valve which T into the main fuel line just prior to the FASS pump. The mantifold has 3 extra ports for Fuel temp and pressure, with an extra incase I change something.
I have bought AN fittings for the entire fuel system.
I have a good sorce of oil 200-250 gallons a month. It is partially hydrogenized, but after a 2 week settling period the hydrogenized oil settles out to 1 gallon, with 4 gallons of good looking oil left, which leads me to my filtering process. Starts with a 55 gallon Poly tank which I have cut 3 5" holes in the top with 200/100 micron filter bags in each hole that the good settled oil gets pumped through. Once my tank is full I will heat x 24 hours (drop in bucket/tank heater) then let it settle again for 1-2 days. I have a drain on the bottom to drain out any remaing settlement/water. My plumbing comes out of the tank 6-8 inches of the bottom through a 1hp Harbor freight pump through 3 household waterfilters (20/10/5micron) then into more poly storage tanks. I will then pump it through a goldenrod 5 micron filter/dewaterer into my aluminum tank in the truck!
With that said, and anybody that is still awake, my question for all the experienced wvo'ers is,
What is the best fuel sending unit to use with wvo? I have searched through old threads but to no resolve! This is the last big piece I need to buy, then it is assembly time! Has anyone used the Moeller marine sending units on ebay that are advertised for wvo use? They have a 3 year warantee on them even with wvo use?
This has been fun, I hope it works.
BTW, I live in Pocatello ID, off I-15, so once I get my reserves built up later this summer I should have extra oil if any one that is passing through needs a little extra.
Once again thanks for all the info
Derek
