Got home today and smelled a strong odor of fuel outside my blazer(2001 4dr 4wd). I then noticed a few drips of fuel on the ground directly below where the drivers side front and rear door come together.

There appears to be a line completely rotted away that rests on top of the frame. I looked around as much as I could along with consulting parts diagrams but I can't go the life of me figure out what type of fuel line this is...return, vent, etc. maybe someone can help me ID it? It doesn't seem to conn t to anything in the rear...maybe that rotted off long ago? The picture of the corroded area is directly above the frame under the intersection of the front and rear drivers side doors (right in front of the body mount you can see in the pic). The other 2 pics are of the lines above the rear axle. One line seem to connect to the evap canister, the other is the problem line that just seems to 'end' and I don't remember where that 3rd line runs to at the moment.

Can anyone chime in? I can't find any parts diagrams that really help out and have read extensively through the search feature on here but with very little luck.

Thanks ahead of time guys! Not what i was hoping to be doing NYE or day but such is life!

 

Not sure why but I can only upload one pic to a post.

 

Last one

 

When checking my post, I realize the pics are showing up very small. Maybe uploading them on a smartphone will help increase their size.

 

Still only allowing me to upload one pic per reply. Sorry for the redundancy!

 

Rotted section below drivers side front and rear door intersection

 

I did some more recon today and from what I can tell the rotted section in the picture is the old brake line (I had it replaced a number of years ago and I think the just cut the front and rear sections off) which made it really deceiving. So the lake must be from one of the lines behind that. This is directly behind the body mount which makes it extremely difficult to see. When the truck is running, fuel is not spraying so I'm guessing it is either a return line or vent line. There is only a small puddle under the spot when the truck is parked, maybe the diameter of a soda can. Can anyone provide some insight?

 

Images are way too small to figure out. 3/8" diameter line is the fuel pressure line. 5/16" is the fuel return line. 1/4" is fuel vapor. Pressure and return lines would leak while running, and for a few minutes after you shut it off. The vapor line should never leak liquid fuel, only vapor. The pressure and return lines can be temporarily repaired using fuel injection rated rubber line and hose clamps.

 

same thing just happened to me, fuel rated rubber hose like captain says, but i doubled hose clamped for piece of mind. you can also flare the ends of the metal fuel line
