gritty oil after fuge

[Cashflo]

Ok making this short cause im on road. Using backup oil that is 3/4 creamy on 600 trip to pickup kids. After first pass on fuge at 180 deg i notice that fluid from bowl on shutdown appeared to be atleast half water. Worried i put it threw another pass but only 145 deg. But didnt watch shut down. After I pumped to my tank in truck i noticed my suction tube for pump had a gritty substance on it. feels like cold waxcrumbles. It broke down rubbing between fingers.

Any idea what it is and should i be worried?

Another Q. Running V3 how can i tell when filter needs changing?


Yes this is me keeping it short.

Animal fats?

[Cashflo]

maybe. I made it back. I made it 552 miles before the 30 gallons of veg ran out. Still had to use 4 gallons of D2 to make it home.

How can I tell when V3 filter needs changing

[vegginpsd]

I know it is supposed to monitor fuel pressure and turn on the D2 pump when VO pressure drops. With that said I recall reading that a light flashes when fuel pressure drops.

If you don't have a pressure guage on the V3, the only way to know your filter is done is by the green light flashing. This is the veg pump shutting off due to the pressure dropping below the switchover point. There is no loss of power at the motor because the diesel pump kicks in at the same instant the veg pump shuts off.

If you have a pressure guage, you can see the filter clogging because the veg pressure starts to drop down below 75psi, especially under acceleration.

Thanks Guys. The V3 is an early 08.... before the pressure relay problems!

I need to load some pictures of my 2 bowl turnkey Simple fuge

I think i cam across what the gritty substance was either sterols (a steroid alcohol) considered as a mushy crystal-like material, or it was paraffins.
