2005 f350 SD FX4 anyone had or have a problem with blowing the O-ring out when towing? the trailer is a 30' 5th wheel. the dealer has replaced the O-ring several times but now its getting old having to take the truck back everytime we go camping. anyone have any ideas on this?

 

i have no idear but i will say this is a new one to the 6.0 forum, least i can remember. Maybe a older user can pick this subject up.

 

HAve you changed the filter or is it the original one?

Here is an update I came across if you bought an aftermarket filter...

January 16, 2006

This bulletin is to inform you of an application error in both the 2005 & 2006 NAPA Application Catalogs.

YEAR APPLICATIONS SERVICE FUEL

Catalog Reads:
2005/2006 Ford F Series w/V8 6.0 L Diesel Engine 3599

Correction:
2005/2006 Ford F Series w/V8 6.0L Diesel Engine N/A
NO Replacement


We DO NOT currently have a replacement part number for these applications. DO NOT FORCE the 3599 into the fuel filter housing, it could damage the fuel release valve.

A new replacement part number is scheduled for release as soon as possible.

A host of changes have been made to the 6.0 litre diesel engine since its release in 2003. A new housing cap was one of the changes made in 2005. The new caps have support ridges which will not allow our 3599 to fit. Pictures of the old and new caps are below.

We apologize for any inconvenience this may have caused you or your customers.

Sincerely,

If you go to Wix's site or Filter 1's you can see that the filter #3599 is not for '05 or '06 trucks...they do show a new filter which is # 33899, but as stated on the site..."is not available".

Now, isn't that just GREAT since a lot of us are using the #3599...wonder what damage we can expect from this abortion

Here's an addendum to the above. I C/P'd this from Filter 1's site:

Fuel Filter 33599 2003-04
Fuel Filter 338991 2005-06

And from FleetFilter:
IMPORTANT NOTICE FROM WIX:

January 24: Wix announced that the 33599 Fuel Filter for the Ford 6.0 diesel may not fit properly in the fuel canister in the 2005 and 2006 models. Ford made a minor change in their filter housing cap that makes the fit of the 33599 difficult.
DO NOT FORCE A 33599 INTO THE CANISTER; damage of the fuel release valve could result.
At this time, Wix has listed on their website that the replacement filter is a 33899.

This information came from FleetFilter.com

 

which o-ring? and if it has been replaced a few times, why has your dealer not been smart enough to replace the whole assembly? Being an 05 the truck should still be under warranty.

 

What would be wrong with relacing cap with 03,04 cap.

 

i havent done anyhting to it, took it back to the dealer when this happens. its the O-ring onthe bowl of the filter housing on top of the motor.

 

Lets just scare everyone into using RACOR! From what WIX personally e-mailed me with IMAGES attached the problem is Ford changed the Seconday Filter cap design for Job #2 2005 Builds and up. I will postpone changing my filters till the new number comes out because I refuse to use a RACOR element.

BTW, thanks for the props Bum I was the one that posted the info you are "supposedly" came across that I recieved in an e-mail from Wix on the 16th..........

 

I had a similar problem with the fuel filter leaking. Couldnt tell if it was from the O-ring or not but I didnt think it was. anyway, took it to dealer and they replaced the whole assembly under warranty and no problems since. I had less than 5,000 miles at the time.

 

I just repaired my fuel filter housing myself after a week at the dealer and many calls telling me I didn't have a leak! Turns out the O-ring sealing surface at the top of the filter housing had several vertical ridges on it (chatter marks from machining). It would only leak on a cold start for a few seconds, just enough to keep everything stinking with fuel. I smoothed out the surface using 280 grit sandpaper and then finished it with 400 grit. Also the cap had some flashing left in the O-ring groove from the molding process. Remove the O-ring from the cap and carefully scrape away the ridges if present. BTW, the ridges on the housing were on the surface toward the front of the truck and only visible by crawling in the engine compartment and looking down on it.

 

Super Duty trucks.... made in Kentucky and QA checked in Alabama. Good info for others to look for if they have the same problem.
