This link simply takes you to my original post about a pump. That does not seem to be the problem.
http://biodiesel.infopop.cc/ev...21076562/m/412100462 Please stay on this Ford thread for responses. When i disconnect the tank fuel line from the pump only slow drips of fuel are coming out. Looks like i now will have to drop the fuel tank (hope not). Any suggestions on best way to check and clean the fuel line? This message has been edited.

While not a permanent solution, how about connecting a compressor hose to the fuel line and blowing the obstruction back into the tank?

Does your pump or your FPR (if it's on the pump) have an inlet screen? Might disassemble them and clean them well and try before dropping money on a new pump.

I checked the pump, it does not have an inlet screen. I removed the pump from the truck, placed inlet in a bucket of oil and attached a pressure gauge and powered it up. Pressure instantly went to over 70 psi before i removed power.

Is there an FPR after the pump?

Just reread FN74s thread.
Does the poppet regulator hold pressure against the 12v pump? Do i have a bad poppet regulator since i know the pump exceeds 70psi? I should have asked in my last post. What is an FPR? (Failed Poppet Regulator?) By the way, thanks for your responses. This also deserves to be stated. When i ran the truck hooked to a jug before removing the clog , it emptied the gallon jug of fuel quickly. I thought it odd, but dismissed it at the time.

Fuel Pressure Regulato - usually looks something like this if it's not internal to the pump:

BTW-I am now going to vouch for the Airtex E2236. IT is the last pump I purchased and installed several years ago and still has plenty of psi as tested in previous post.
Now to figure out where the fuel pressure regulator is and how to remove. Is there a test for it?

The FPR should be right by the pump or depending on your fuel system architecture on your regulated return.

I see you have a 2001 diesel excursion. Engine should be the same as mine. Will you take a look to see where the FPR is?

I believe in the stock setup fuel pressure is regulated by the oem fuel bowl. If the fuel bowl has been deleted, then the FPR sits in the valley typically.

Hello.....I'm still new to running WVO (I'm blending) and I have an '03 X w/ the 7.3l. The only issues I've had so far w/ low fuel pressure was due to dirty/clogged factory screens in the tank. Just curious, have you done the tank mod to your truck yet where you delete all of the screens and plastic in the tank and rebuild the pickup out of ss tubing? Unfortunately, this happened to me right after filling my 44gal tank.....that was heavy and not fun! If you have not done this mod let me know and I can dig up the site that details it. But once I did this installed a goldenrod water/block filter before the factory fuel pump, replaced the fuel pump everything has been working great. I do not know of the FPR yet....just a noob offering my 2 cents! Todd

Pretty sure this is referred to as the "In-tank Hutch mod", and no I haven't done it as the only thing that gets in my oem tank is #2.

My truck is still down. Two mechanics i have discussed this with ( separate shops ) both doubt it is the FPR. Frustrated at not getting the truck running already.
I anticipate putting it in a shop first of next week. Trying to decide which one.

I'm really sorry to hear that! If you are running two tanks, one WVO and one #2, will the truck run on either tank? You also mentioned the truck ran pulling from a bucket or external source.....is this still true? It sounds like a tank/pre pump issue if you can run the truck w/ external source. It may be worth dropping the tank before you send it to a mechanic....I guess it depends on your finances! But from what I've read it sound like an issue between the pump and the tank.....or am I missing something. Sorry, I'm only trying to help; not frustrate you! Good luck! Todd

twtcad as my signature states, the single OEM tank only.I know you are trying to help.
I found a good slide show on an unofficial ford site ( http://www.ford-trucks.com/forums/index.php ) showing where the regulator is and how to shim it. I have shimmed the FPR and my pressure is now above 80psi. My truck is still not running right , but i hope it just needs a running purge. My FPR housing has center damage and allowed the spring to extend through it. How it got damaged??? Soon i will purchase a replacement housing ( http://www.dieselorings.com/in...od=63&cat=18&group=6 ), but the shim should get me around that for the moment. It is not fixed, but better.

I have replaced the housing, which needed to be done. Center had collapsed. I now suspect when the housing collapsed, it caused other damage. Scheduled to go in the shop.
