Keith Browning Posted April 22, 2012 Share Posted April 22, 2012 Anybody ever come across this? I have seen a couple of trucks doing this, just not as bad. It sounds like a valve in the fuel system chattering and possibly resonating at the secondary filter. It could even be the filter. Just a guess. Anybody?

Brad Clayton Posted April 22, 2012 Share Posted April 22, 2012 See it lot up here in the sticks. All the do-it-yourselfers don't get the primary fuel filter bowl tight. If it's backed off just a smidge it will make funky noises in the fuel system. There's a message about it on FMC. Quote Link to comment Share on other sites More sharing options...

Brad Clayton Posted April 23, 2012 Share Posted April 23, 2012 I can't find it now that I am looking for it. It has disappeared into cyber space. Quote Link to comment Share on other sites More sharing options...
cbriggs Posted April 23, 2012 Share Posted April 23, 2012 I think it was an ssm. I remember seeing it, But as you said, its gone. I have heard the noise referenced ( or what I assumed hey are meaning) in the ssm about being below 1/4 tank. Quite anoying. Quote Link to comment Share on other sites More sharing options...
lmorris Posted April 23, 2012 Share Posted April 23, 2012 Honestly, IMHO, if these guys are letting the fuel level get below 1/4, they deserve to put up with the noise. Too much can happen on low fuel levels. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 24, 2012 Author Share Posted April 24, 2012 The truck in the video had an Airdog installed which had a problem that ultimately caused a restriction. Apparently the blown fuse from that install also disabled the low fuel pressure warning switch and the fuel restriction went un-noticed.

One would have to tell me why replacing the secondary filter (a second time) cures the condition. I admit that I haven't taken the time to inspect the primary filter, but the concern has been cured without touching it. Yes, I have seen this condition SEVERAL times - once after the filters were replaced in our shop. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted July 29, 2012 Author Share Posted July 29, 2012 Here's a new one. I have also attached the Job Aid file Quote: Jul 25 2012 4923 -2011-2012 F-SUPER DUTY - 6.7L - DIESEL FUEL CONDITIONING MODULE (DFCM) SERVICE JOB AID 6.7L DIESEL FUEL CONDITIONING MODULE (DFCM) ARE BEING REPLACED DUE TO NOISE. ENGINEERING REVIEW FOUND THAT DFCM NOISE IS NOT TYPICALLY A CONCERN WITH THE DFCM BUT A RESULT OF AIR INGRESS OR RESTRICTIONS IN THE SYSTEM. A 6.7L DFCM NOISE/REPAIR JOB AID IS AVAILABLE ON PTS TO ASSIST WITH IDENTIFYING THE MOST COMMON SOURCES OF AIR INGRESS OR RESTRICTIONS IN THE SYSTEM. THIS JOB AID ALSO CONTAINS TIPS FOR FUEL FILTER REPLACEMENT AND FUEL SYSTEM BLEEDING. Quote Link to comment Share on other sites More sharing options...
DieselD Posted July 31, 2012 Share Posted July 31, 2012 Interesting. I have always cycled the crap out of the pump after changing fuel filters or working on the fuel system on anything diesel. I love when the lube kid hits the key right after changing the filters and cant figure out why it wont start That should be stuck to every lube kids forehead Quote Link to comment Share on other sites More sharing options...

YukonTyler Posted August 12, 2012 Share Posted August 12, 2012 Had one of these on Thursday. Drilling truck was trailered in with 105 000 km on the clock and an original secondary filter (triple pipe not dual) that shooting fuel like a geyser at key on. Did both filters. Got the primary screwed back all the way - right against the 'stop' and where the wiring pigtail will just perfectly line up with the sensor away from the framerail. Cycled 6 times for 30 seconds each before cranking. Was good - no noise. Hauled it out and it started to whine in the parking lot. Another 6 or 7 key cycles before the next start killed the whine.

Mekanik Posted February 25, 2013 Share Posted February 25, 2013 I've got one right now that our Quick Lane did fuel filters and it has the noise. The noise DID go away aftger I replaced the secondary filter, but after doing a really good inspection I noticed that they over-tightened the primary fuel filter cap. After idling for 10 minutes the noise started to come back again. I have had other ones where replacing the secondary filter took cake of it and one where replacing the O-ring for the primary filter fixed it. As many fuel filters I've done on these I've never had a problem. All the ones that come in with a noise were recently in our Quick Lane. Not to hijack a thread but I think Quick Lane does more damage than good. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted February 25, 2013 Author Share Posted February 25, 2013 I wonder how many times the primary filter cap o-ring does not get replaced It's kinda out of sight and outta mind. I still see 6.0L oil filter caps with well aged flat o-rings. Quote Link to comment Share on other sites More sharing options...
mchan68 Posted February 26, 2013 Share Posted February 26, 2013 I wonder how many times the primary filter cap o-ring does not get replaced It's kinda out of sight and outta mind. I still see 6.0L oil filter caps with well aged flat o-rings.There's no excuse for this type of crap to go on at all. Given the fact that every filter comes with a new o-ring, I can't see why anyone would be too lazy to change it out. That's just like removing the new rubber gasket from a new spin on style oil filter and reusing the oil rubber ring in my opinion. Now, when upselling a new oil filter cap (which I'm sure many of us have had to) due to the vehicle having one of those garbage aftermarket oil filters, sure we're going to have an extra oil filter o-ring to put in our box, since both the new filter and cap both come with them leaving one extra.

And when they come in leaking oil all over the place and you tell the guy the filter oring is leaking, you get a good laugh when the guy replies "But I just changed my oil filter not to long ago!"
