Hey guys, I have been smelling fuel the past day or so so i got under the hood and I'm leaking fuel out of the bottom of the fuel filter housing. Please forgive me I'm not sure what everything is called so i will do my best to explain it. It looks like it is leaking at the bottom of the housing that u take of to do the spring upgrade, its not a really bad leake but enough that it needs fixed. I hope I didn't lose you and i hope it makes sence.lol

And yes I check to make sure everything was tight, oh I just did fuel filters 2 weeks ago with OEM filters.

 

Make perfict sense

Need to replace the Keyhole Gasket ASAP cause it could cause Low Fuel pressure and ruin Injectors

Either this or could be runing down from Cap


Is this the spot your leaking Fuel out

 

I'm assuming that housing needs to come off to do that right? Do u have a part number, and thank you for ur help!!!

 

Blade sorry, yes that is exactly where it is leaking from!!

IDK if the second one down from top is the keyhole gasket or not the oring seal is throwing me off alittle here

If you havent done the blue spring mod now would be a good time

 

You read my mind, I will be doing the blue spring, do I need to replace the housing?

 

No yoou can reuse the Housing but to get the Keyhole gasket you might have to get the whole kit IDK some places will sell just the spring You will have to ask the parts guy

I went with the whole kit cuz I wanted all the gaskets and orings in case I need them

 

I'd buy the whole kit. Had one last month leaking from there and there was a small crack in the housing.

 

Blue spring update complete!

It seems to start and run a little bit better, thank you for your help!!

 

Simple right

And now you dont have to worrey as much about low fuel pressure Killing injectors off

Could you tell what was causing the Leak???????????

 

Yep very simple!!

Yes I could see that the bottom of the keyhole gasket was not making a good seal and that's were she was leaking from!!

I feel better that its don like you said. Thanks again man!

Blade you have helped me with a lot on this 6.0 from a egr cooler oil cooler egr codes and know the blue spring so thank you man!!

 

when you started the truck up in the morning time did it sputter for a lil bit and then clear its self out after it warmed up?

 

This sounds more like a FICM or injector issue.

 

i just replaced the ficm about 6 months ago i do have the same leak as he does after about 3-4 mins of driving it runs like its suppose to like it has air in the fuel line

 

If your leaking fuel you could have low fuel pressure Fix that upper fuel bowel first

Low fuel press will kill injectors

also smell oil does it smell like diesel fuel watch for few see if your making oil for awhile I checked mine once a week for a couple weeks shure enough them injector orings was leaking
