Anyone know where to get an electronic fuel pressure sending unit that is WVO compatible? I replaced my lift pump after seeing low pressures on the new gauges and it doesn't seem to have helped. I plan to try a mechanical gauge this weekend to make sure that it is the gauge and not another bad LP but I am thinking that the sending unit was not compatible. And just a note but I see the same pressures with WVO and #2 alike so it isn't the difference between the two.

 

I would think any sender would be compatible with WVO.
Actually diesel fuel is incompatible with more materials than most other fluids.
Here's chart relating to o-ring materials but many of the same materials are used for hose, sender diaphragms, etc.

You might look though the chart, I'll bet it lists materials compatible with veggie oil, I know it lists the ones compatible with beer.

Personally if I found the sender to be shot I'd just replace the FP set up with a mechanical gauge.
Much more reliable.

 

Got another sending unit this morn but won't be putting it in until I get the tranny rebuild since I lost 1 and 4 this morn. It's toast.
