I have done a search and just cant seem to find it. Im looking for a diagram of the fuel lines on a 1991. If anyone has or knows where I can get one please let me know.

 

You've got to be more specific. Are you asking about vacuum lines or wiring diagram for the fuel pump?

 

no the actual lines and which one is which. The problem im having is I have fuel spitting out of what appears to be a vent line. so before I pull the tank to inspect I would like to have a diagram of how and what the lines are. I have a Chilton manual but shows nothing.
keep in mind this car was a tbi car and now its a tpi, don't know if that matters

 

bth_thelines.jpg?t=1361637518maybe something like this but for 91. would help alot

 

sounds like the vent valve is bad next to the tank or are you saying fuel is coming out of the evap canister ?

 

The 3/8" is the feed, the 5/16" is the return, might be 1/4" for the vent (should have a spring clamp). Use open end wrenches to figure out the sizes.

 

if the fuel is coming out of the ccp canister replace the filter ACDELCO Part # A478C

super cool man thanks and yes fuel is coming out of vent number 17.

 

did you get this from a service manual

 

I got it from the parts manual. Part number 17 is discontinued start looking at the junk yard or post in the wanted classifieds.

 

If you can purchase a vented gas cap it would do the same thing. The vent is a one way check valve to let air into the tank.

 

thanks man im going to find a vented cap and see what happens. thanks again now you got me looking for a parts manual
