Sounds good to me so far then, not that matters even a Penney.


So it's down to space and cost comparision. Also factored into that is how low of a PPM is needed. What is the PPM standard accepted for Diesel and Bio-D? I forget.

Less than 500ppm is generally accepted but I go fo less than 1/2 of that to allow for some condensation getting into the fuel later.

Why 1/2? Would think that this 500ppm has also taken into account condensation since the others are also used in the same environment. Thus no need for the 1/2 your cutting it down to.

500ppm is the petro diesel standard and many diesel vehicles have water separators that actually do remove water from DIESEL fuel so the engine is often getting less water than what was in the tank.

WVO tends to increase it's water content in storage and the water separators aren't effective in removing water from VO so my personal opinion is that WVO should start out with lower water than Diesel to get to the same water level by the time that it gets to the engine.

Since I have no problem getting my oil down below 250ppm and I have had no fuel related engine problems in over 30 years, I'll keep doing what has worked for me.

My fault for not being very clear about an on board CF. I didn't intend to use the SimpleCF while moving, but rather start the cleaning cycle when parked for the night - campground. Thanks for all the posts. It was interesting.

since they can handle the forces of a multiple horsepower electric motor's rotor at 7,000 rpm


smoothly actuated g loading at 1G is quite different than instantaneous g-loading such a hitting a pothole or bump - or even the way some ppl
drive :lol:

shock and vibration is an engineering speciality and still not completely understood (to many variables) - the higher paid pros fly around the world
just to roubleshoot everyone probs!

if to be CF'ed while in transit, at a minimum would suggest application specific shock mounting/damping and some SFI rated ballistic blanketing as is used in hydroplane boats and drag racing or it could end up becoming a real drag! :(

Wow !! You guys have so much experience about filtration systems.I am using an Aprilaire water filter . I do know some of the functions but really I've never been deep inside the technology . Salute You Guys !!!!
