The fuel filter blew through, and tank gunk plus filter bits went all up in the injectors. The worst part - I was running on diesel at the time.

Pity me.

Oh yeah, it's a 2002 f-250

Isn't there something to run through and clean out
the injectors?
What happened to cause this? I heard bioD will eat away a the stock fuel filter.

Also interested in what you think caused this. Please post info on cost and work involved in the fix-up (I'm also running a PSD). Thanks - Patrick

What kind of filter? I've never heard of this particular failure. I use Racor filters on the WVO side, and the factory/OEM filter on the diesel side. Never a problem (other than needing a change when spent) so far.

Cheers, John

Tried it. Didn't do anything.

Both a stock filter and a goldenrod filter did that. The stock one just collapsed in on itself, while the goldenrod kind of blew apart and left filter chunks all in the lines.

The stock filter could have been from a tank of biodiesel I used (though it was rated for biodiesel). The goldenrod . . . poor quality? Both of these were hooked to the stock fuel pump which IIRC shouldn't push more than 55 psi, what the filters are rated for.

Goldenrod filters are made for gravity filtering of agricultural fuel and not rated for pressure or vacuum per the manufacturer.

Sounds like something happened with the pump. I've heard of filters caving in due to heavy dirt buildup. Did you post to the DieselStop Forum? Anyone know the least expensive route for him to get his truck fixed?

check on the www.ford-trucks.com forum. I can't remember the company name, possibly giant. They sell a cleaner and jug kit for about $40 called molley-lube or something.
There were a lot of positive responses from posters about ip and injectors making amazing comebacks.

I couldn't find anything on the ford forum. Sorry , I tought that was where I saw it.
My goldenrod filter said it was rated for 50 psi, but not advisable for bio-d.

That depends on which goldenrod model. They make a metal cartridge filter that is rated 50psi, printed on the can. The amber transparent plastic ones are gravity only. I have both.

When some filters paper gets wet enough they can plug up and then disintegrate.

Is the truck able to run or is it dead? You could try the lubri-moly if it is running (my NAPA autoparts store now carries lubri-moly). If dead, I'm afraid the injectors will probably need to pulled, cleaned and tested. Go to ford truck enthusiasts for how to pull the injectors.

jordanmills, which Goldenrod filter did you use? Did you have a pressure gauge? Were the filters clogged? Please describe your system.

They said right on there that they're rated for 55 psi. The pump claims an output of 50 psi.

I used the canister filters that sunwizard mentioned. Didn't have a pressure gauge. The system is described elsewhere, but it's basically diesel tank to fuel pump to filter to solenoid valve to the stock fuel lines. The SVO tank also goes to a fuel pump, then a heat exchanger then filter, then to the solenoid valve. I did compensate for the excess fuel carried in the stock filter bowl with very long purges - a spot check for coking on a pulled injector revealed very little, so I doubt it was a contributing factor.

Do you have a diagram of your system? From your description, am I correct that your OEM filter is used for both diesel and VO? What ambient temps did this happen at? Do you have a heated wvo tank? Please describe how you process your wvo.

Pardon my handwriting.

The OEM filter was removed, filters were placed on the separate diesel and SVO lines. I wanted to keep the OEM filter there too as a backup, but I couldn't get flow through both filters.

This happened at engine temp, fuel was running 180-190 if the engine temp gauges was calibrated the same as when I tested it. It was about 95 F outside.

I have a heated pickup in the WVO tank.

I run my oil through a large screen (window screen), then let it settle 50 gal at a time. I pump the middle "good" stuff out, filter it to 10 microns, then let it settle again. I drain off the water, if any, then test the oil for water. When it passes, I put that in the truck.

The pre-powerstroke injectors have ( I've been told) a screen at the inlet of the IP. Don't know about the powerstrokes. I have a glass inline filter just before mine, which does catch some small stuff from time to time.

The 7.3 L (and maybe others) have check valves where the fuel goes to the heads. Those have little screens over them. But this stuff was too small to clog them.
