I needed a new fuel pump for my 97 Bravada. It Is a delphi fg0071. Followed the directions installed the new harness and put everything back whereit belongs. The issue im having is that the center line keeps coming off. I am pretty sure that is just the vapor line as it didn't have a clip when I removed it. Problem is fuel is being dumped from it when the line pops. I have checked and it is the middle line. Today I started it up but noticed the fuel pump stayed on and then the line popped dumping fuel everywhere. What the hell is going on?

 

try replacing the fuel relay. It could be stuck overloading the system.

 

Replaced the relay. Made sure the lines were on there tight and it still keeps blowing the line.

 

I need to replace the fuel pump on my blazer also. looked on youtube and saw a guy changing his. HIS fuel pump had 3 lines coming out of the top of the fuel pump assembly.
ALL 3 had clips on it. maybe your was just missing? still on old pump? try a small clamp?

 

they do all three have clips the middle line is a vapor line if its just a clip you need you could probably just find that at a junk yard hell I have on settin out to bad shipping is a pain as if that don't work you may have to get a whole line if your actual line may be broke (they are friggin plastic) so if you cant get the clip or whole from a junkyard well that would be a dealer item as it is formed hose for that purpose...good luck no idea why it would shooting fuel out the vapor line
