Thats the old style sensor though, the new style has no mounting holes

 

Do you have a P/N on those fittings?

 

I hope you guys are running a water filtration unit with flex fuel... These are hygroscopic sensors, so if you want any accuracy you MUST run water filtration.

 

I've seen that video but I didn't know there was a water filtration system to use. Got any more info on it?

 

Seeing water doesnt separate from e85 like it does with petrol i guess the usual water filters wont work right...

 

I don't see why a Diesel Water Separator unit wouldn't be a perfect match for this application. Just make sure it's under 40 micron.


You'd run this BEFORE your standard fuel filter, which should be 10 micron or smaller.

For instance, my setup is going to be something between 9000-11000cc/min of maximum fuel flow (142-174 GPH) and I'd want a dedicated 10 micron water separator (it still filters the fuel) before my 3 Micron Fuel filter/Water Separator combo unit.

Here's a good option for me:
Racor Filter 1000FH10 Diesel Fuel Filter Water Separator

 

Interesting. Do they use these types of water separation filters on factory flex fuel vehicles?

 

No. And the sensors don't have problems, either.

 

really good view. Really if your draining your system well enough between changing fuel types going up to E85 doesn't really matter about water in the system.

 

Does the ethanol and maybe 2 stroke oil effect the life of the diesel/water filter unit?

 

Really interesting! Very curious as to why there would be a need to run a water separator before a Fuel filter/Water Separator? Just extra protection or expecting that much water in the system? Wouldn't draining a Fuel filter/Water Separator every few thousand mile be more then enough? This Fuel filter/Water Separator looks to be very capable and inexpensive.

I have been running E85 for over 5 years and have been monitoring my E% with a sensor for 4 years. I do live in a dry climate but have never seen an abnormal jump in E% across the seasons ever in my car. Winter here is AZ is always 75 to 77 % and summer is always close to 85%. Car always sits for 3 months or so during Summer/Monsoon season with a full tank of E85, which is our most humid. I am sure water does get into the system but for where I live there is no way it is close to the ration of water and fuel in the video.

 

In that video the water isnt mixed with the fuel like it is when mixed with e85. So is that filter going to be able to remove the water when it is completely mixed into the e85?

 

Yes, did you see the video and links of the products I posted?

That's exactly what happens.

 

I would recommend researching that more and am fairly sure those filters either won't separate water from E85 or if it does then it will also likely separate out ethanol with it. Water and ethanol bind together on an atomic level. The diesel water separator filters works on the principle that the water and diesel are not binding, but instead are two distinctly separate fluids, i.e. they have phase separation.

Phase separation in E85 occurs at about 20% water. One phase is gasoline and the other phase is the atomically bonded alcohol/water. When that happens I'm fairly certain the filter you noted will fill up immediately with ethanol/water because it will be trying to scavenge out the 15% fraction of gasoline-only to send to the engine. That assumes it will efficiently separate anything at all in this particular case, which is still quite different than diesel & water. It typically requires distillation to separate water from alcohol due to the atomic bonding. Otherwise every distillery and moonshiner could just filter out the water to make booze.
