my 05 f-350 works great with bd except for the filtering, it will filter 1 or 2 tank fulls of bd with no problem but then it begins to clog, i remove the filter and notice no dirt! but i do notice the filter will not let any fuel pass through it when i manualy try to pour fuel through it. i filter my crystal clear, washed, bd through a 1 micron home water filter before pumping into my truck. this is the 10th time this has happened. the trucks been running bd since new. i put petro diesel in when i notice the filter is cloggeged, after a few miles it frees up??? i noticed the new truck filters are called "fuel/water filters" is this a filter that clogges once water is detected? is there something in bd other than water that makes this filter think its water? my bd is crystal clear, there is no water, i pump dry it with convection... any ideas? i believe it is something to do with the filter maybe being a water block filter, im not sure if it is or isnt. i use motorcraft filters. this is really anoying, i remember someone once posted this, im not sure if this issue ever got resolved?... any input would be great, thanks

Sounds more like saturation verses dirty. Yes, the combo filters will get this situation effect quickly. All the water filter usually consists of are some cotton balls. This type of filter is designed for the general use of consumer purchased diesel, not our BioDiesel. I use only WIX brand filters, and that is for the reason "they are a damn good filter". Have you tried a marine filter system just before going to the tank? I have a filter system on my storage tank pump to my truck. Those 6.0s are finicky about everything! Clean n Mean...

wix oil filters? i dont think they make an oil filter that can fit in my 05, 6.0 fuel filter holders. remember their are two filters in the 6.0, one at the motor and one under the truck, one is a 10 micron while the other is a 4 micron filter. what would be the best way around this set up? do they make non-water block filters for my stock filter set up? thanks

I'm sorry about that type o. I ment to say "fuel" filters, and also "when available". I didn't by any means want to give the idea of replacement of fuel with oil filters. I do want to restate that Ford modified their fuel intake system filteration due to the concerns of poor quality commercial fuel. I DO use a old school mechanic's trick by filling 3/4 filter full of transmission fluid, 1/4 diesel for prime. The tranny fluid is believed to keep the injection system clean... I found that it also conditions the filter and system for BD. I have been doing this way before I started Brewing and just kept doing it. Found that I didn't have as many of the common problems as reported in the forums. Good luck. Later Clean n Mean...

thanks for the input but the info i am looking for is how do i make my db so it doesnt clog up my filters, i dont know what it is, its not dirt, not soap, not cold, not water. i filter through 1 micron before entering fuel tank.... weird. should i put the bd through a series of filters before entering my fuel tank, like a water block filter, then a 1 micron filter. its so strange. maybe there was something in my tank, i did put a diesel additive in recently when i had bd in it... i also tested my ford fuel filters to see if they are water block filters, and the result is that they let water through them, so i know they arnt getting clogged with water as well. once filters are clogged, i run petro diesel and they free up real fast. anyone know what this is??? Thanks

Midnight I was thinkin about your problem. Try a gallon or 2 or k1 in a tank full of bd, that is what i use in the winter to keep it from jellin up when it gets cold with a blend. I will bet it will keep your filter from pluggin up and give it a little more pep. Jammer

That's weird, I know someone with an '05 and as far as I know there have been no filter problems.

thanks jammer, will do, what exactly is k1, not sure what that is?

K1 is Kerosene , or #1 diesel fuel.They use it for the torpedo style heaters for shops and barns. You can get it at gas stations, make sure it's not red. Jammer

Midnight, I forgot, are you using 100% bd? If so, maybe at night the temperature is causing the bd to gel. This time of year, I am planning to use a 50/50 blend. Hopefully that will prevent any clogging. Please let me know of any other problems. I am about to put my first bd in my 2004 f250, and I will abort if things aren't going well with your truck. 2004 F250- 6.0 Turbo Diesel God is Good, All the time!

Midnight, I think Lanetang is right- the petro diesel that you put in after the filter clogs is creating a mix with a lower gelpoint, thereby freeing up the filter. Incidentally, we've got a number of happy customers with 6.0L Fords, using B100 (or close to it). Do you know the cloudpoint and gelpoint of your homebrew?

the cloudpoint is around 40f. i never have this problem as i am in south florida. its not because of this. its something else, i am going to keep playing with it and let everyone know what happens.

WELL,WAZUP????? Jammer

Midnight What is the verdict?

Would it be worthwhile to try a few tanks of commercial biodiesel just to take one factor out of this problem? By trying the same number of tanks that it took to clog your filter using commercial biodiesel would confirm that it's either a compatibility issue, or it's something with your biodiesel production that's causing the problem. I am by no means an expert in biodiesel, but that was just a thought to try to confirm that BD is the actual culprit and not some impurity in your biodiesel.

I have 20000 miles on the same set of filters in my 6.0 running B90 (about 10% Kerosene) I changed the filters when I started using Bio and never looked back. I too live in Southwest FL so temp is not an issue. I like to add a bit of kero to my fuel to thin it a bit (and keep the cat from drinking it) You might consider having some of your fuel tested. I have only plugged one filter and that was on my 04 Jetta after 100 miles on Bio and no prior filter change.

hi all, well my fuel lift pump went bad after 1500k of b100 use in my 6.0 psd. the pump would run when i tested it out once i removed it from the truck but when i put biodiesel through it it fouled up and barley pumped. weird, maybe it was just faulty? or it burned up from running clogged filters over and over. I now got a new stock fuel lift pump and am going to try bd again. I want to put a raycor marine diesel 10 micron fuel/water filter before the lift pump, and remove the filter inside the lift pump. This test should rule out any stock filter problems if there is any since marine diesels are known to run biodiesel. and if the pump goes again, i want to put a mallory 100psi fuel pump in and remove the stock lift pump assembly. RShrimp, do you make your own BD?

Yes I do make my own. About 50 gal a week for over a year now. I make 2, 100L batches and then wash/dry them together in a 55Gal cone bottom steel drum (67 gallons with the cone on the bottom) I have a good source of oil from 1 large resteraunt and I dont even titrate it any more. It is always been 3.5 to 4 so I just use 1100g of KOH in 5 Gal of Meth for each 100L batch. If thats too much it comes out in the wash. I consistantly get 5.5 Gal of Glysoren out of each 100L batch. I use a 50Gal water heater 135-140degrees F and about 5psi. Mix for an hour and then move to wash tank. Wait 20 minutes and then drain off the Glysoren while it's still hot.

heck, i make 45 gals pr week for a year now, I first do a safety boil off in my custom heat system, i get my oil to 250f in 1.5 hours, my oil titrates any where from 2.-5. i use caustic soda. I use 22% meth, or 10 gallons meth for my 45 gal batches. i use 5 grams caustic soda plus titration amount. I make sure my oil is in between 130f -140f before processing. I process for 4 hours and wait 24 hours until glycerol drain off. I wash my fuel until the water is perfectly crystal clear even with the most vigorous bubble washes. then i pump dry the fuel until sparkly clear. I do a shake test on every batch and get super clear results. My wash system is automatic, it mist washes for 2 days then bubble washes for 1 day. I never even have to look at it during its wash times, my system auto drains the water once full wich is about every 3 hours and repeats itself over and over. I then filter it with a 2 micron home water filter and pump into truck from my gas pump set up. my fuel is always consistently clear etc... and i always do two titrations on every batch. i just think the ford filter sys just doesnt like bd, i do feel it may be too thick for it and needs to be thinned. I will keep everyone posted how my new stock pump works...

Midnight- I have an '05 6.0L PSD on an E-350 cargo van. Your F-350 has a horizontally mounted fuel conditioning module (HFCM). The E-series vehicles have a standard mounted FCM. I'm very interested in the issues you are having with the fuel filters and the replacement of your lift pump. Some questions: 1). Do you have a small centrifuge to test for BD water content? 2). Have you ever had your Water in Fuel light come on? 3). What diesel additive did you use with your BD? 4). Have you ever had your fuel tested for total glycerine? 5). Which filter was clogging; the 4 micron? 10 micron? Both? 6). Do you have the Raycor 10 micron installed now? 7). Did you replace the other 4 micron fuel filter? 8). Is your 4 micron filter integrated into the lift pump? RShrimp- What year is your 6.0L PSD? What type of vehicle? TJ..
