Baldwin BF1212 prepump water separator and freezing conditions
Going to be dropping down to 0 and below this week. I have the Strictly Diesel hutch mod kit with a Baldwin prepump fuel/water separator filter installed.
If I happen to get a crappy batch of diesel and it fills up with water, which then freezes, would the filter keep my truck from starting? Or is the filter designed that fuel would still flow? I'm wondering if I should keep a spare filter on hand.
The water would have to fill the outer area of the filter before fuel would be restricted. You can run isopropyl alcohol (a.k.a. heat and other brand names) to traverse water through the fuel system if you suspect a bad fuel load.
The best bet is to drain the filter / water separator now and anytime you think there is a bad fuel load. I would also keep a spare filter for the "just in case" need.
Don't change it unless you need to because it puts air in the fuel system.
I also installed the same hutch mod kit myself because my fuel bowl was constantly full of junk (mainly sand, rusty etc.). I had gotten a bad tank of fuel. Dropping the tank and cleaning it out did the trick. However, there is still residual crud in my fuel lines even though I have run multiple tanks of fuel. I am convinced that Bio-Diesel is what will cause this to happen. Nonetheless, any time it drops below about 15 degrees, my truck constantly gels up. I have just filled the tank and even put fuel preventative additive in it. I am convinced that the little plastic filter is causing restriction on the tank. More specifically, I think that the reason it is causing restriction is due to a residue from Bio-Diesel and residual crud in the lines. The filter is so small that although the diesel may not freeze, even minimal crud inside that tiny filter is enough to cause restriction. My tuck starts no problem, but will constantly start to gel up after about 10 minutes or less of driving. It also idles fine. I will replace the filter in the spring with the racor unless you guys think my problem is elsewhere.
My father has the baldwin in his 02 F250 (I installed it). He hauls RVs to dealers from the factory and has had many problems with it, mainly when it is -10F and lower. He also has to fill up in many different locations across the country and cannot know how each stop keeps their tanks.
I've had my Baldwin 1212 in longer than he has and never had a problem. There is a new filter there now because of other issues (it was a troubleshooting step), but there is a water / crud filter there.
I plan on putting all my filters in a box under the bed. I have a coolant and pre-pump fuel, I plan on adding a bypass oil and trans filter in an under bed box. I will do a write up when I do it for the truck in my sig.
Box will hang just in front of the wheels, behind the cab.
