I have a friend who has a 00 blazer. His blazer died on him on the freeway the other day and thinks the fuel pump is bad. I take a look underneath his car and look around and notice a hose that is split and barely hanging (not plugged in) next to the 3 fuel lines (and close to the fuel rail). After looking around and moving the hose throughout its diameter to try to find where it connects to, I am at a loss. I need some help. I scoured the internet trying to find any good pic of the underside so I could find the same hose and thus figure out where this hose end is supposed to connect to. Can anyone point me in the right direction?

P.S I can hear the fuel pump when I turn the key, so I dont think the fuel pump is the problem, but want to figure this hose thing out before I start checking other possible culprits (fuel filter, spark plugs, etc.)

 

why not take a pic of the hose in question so you can show us what's the problem - photobucket hosts images for free and just wrap the link in [img]linkhere[/img]

this will show it all. btw from what your saying the fuel rail i suspect your not looking for a diagram of the UNDERSIDE of the blazer but more or less a pic or diag of the motor bay.
