I have a quick question regarding smelling diesel fuel, everytime i go to start up my truck and when i walk around the front of the truck i can smell fuel and when i enter the cab i can smell it as well just wondering if anyone has any ideas what it might be

Thanks,
Bob

 

Check the little yellow lever on the backside of your fuel filter bowl, I just bet that the O-rings are leaking. Just follow the tube down and see if it is dripping, or fuel is laying in the valley. There have been alot of posts about this problem, lately. Just do a search for leaky o-rings , and read on.

Look in the valley behind the fuel filter housing it may be puddling there. The Drain valve on the back of the Filter housing is sealed with a pair of orings and has become a common occurence in the past 3 - 4 months

 

If the fuel thing is not it, possibly the exhaust has a minor leak. Do you have the defrost on when you styart your truck?? If so try it without and see what happens or try it on the A/C mod and see what happens. If it doesnt happen with the ac on it could be a exhaust leak too. Might be time for that new 5 inch exhaust you been wanting !!!
