Strong smell of raw diesel.

[rrambo]

Good morning brothers,

My SD is a 2005 that is stock as far as I know other than flashing a tune Friday from Vivian at quick tricks. (Looney)

I bought the truck a month ago and the strong diesel smell started before I flashed.

I can't use the hvac unless I make sure recirculation is on. If I open the vent or the windows, the smell will just about run you out. Even after parking, the whole area around the truck smells like diesel.

I'm pretty sure it's not exhaust, to my nose it smells like raw diesel. But I could be wrong. I don't see any obvious leaks but then again I haven't had time to thoroughly look either.

I googled last night and came up with about a dozen things to look for but I wanted to get some advice from the experts on here.

No, I'm not monitoring yet because my SCT TSX won't connect to my android phone yet. I had to borrow an iPhone to flash my tune. But before I flashed I checked for codes and there were none.

Sounds like a common problem is the o ring on the fuel regulator, but I'm not entirely sure how to check that.

Any help is appreciated.

Does the smell remain for as long as youre driving. Or does it go away as the truck warms up?

Before, during and after.. it never goes away, cold, warm... doesn't seem to make a difference.

any dripping fuel anywhere? my buddies was leaking at the fuel pressure regulator. i would start with the lines leaving the tank and trace all the way up to the fuel filter then down to the front of the heads.

Nothing obvious, but then again it seems like I never park in a clean parking place to begin with.

This weekend I'll try to start at the tank and go forward.

Mine was leaking at the cover for the fuel pressure regulator spring(where the blue spring goes) This is located on the secondary fuel filter housing...sort of "key" shaped.

So if it is leaking there, and you change it, is it a no brainer to also do the blue spring?

yes, order the blue spring update and when you take the housing apart all you have to do is swap in some new parts, no extra work required! Takes 30 minutes

Just get the updated spring kit from a dealer (Very good prices from Vendor dealers)
and you will get everything you need to stop the leak and solve the FP issue!

Sweet.. I'm kinda hoping it's leaking there now!

By the way.. I'm a decent wrench.. four wheel drives, muscle cars, Harleys.. but this is my first diesel truck.. I do have a diesel tractor but it's old so that's not really the same..

What all is on the way to get to the regulator?
