96 bonneville gas leak
Hello all. Well first I am new here and I am glad this forum exists. I am here mostly to learn since I am a beginner to the car world. Everybody starts somewhere right?
Well yesterday, my bonneville turned off on me at a stop light. I managed to Start it up again but it seemed like it was giving itself gas and thrusting forward without me doing anything. There seems to be a lot of gas leaking from under the hood but I do not know where exactly it is coming from. Any help would gladly be appreciated. I need to get my car running for school. Thank you all.

its not the */c one is it? take the cover off the top and check out the two lines you can seperate the connectors with a pair of pliers push it toward the engine squeze the white part and pull up on the black. there are orings in there that sometimes need replaced, take them to the parts store and get some new ones

I doubt it is your FPR, if you want to test it just remove the vacuum hose from the FPR, and wait a minute or two to see if fuel comes out of it.
Here is a video if you want to check it out.
I am with Justin on the culprit, the o-rings for the rear fuel line on my 96' PA started leaking, I could easily press down on the connector when the key was on, and fuel would squirt out of it onto the intake manifold and fuel rail.
Give this connector a little push down when your key is set to ON, and see if any fuel squirts out, if it does the o-rings will need to be replaced, and that job was not easy for me, the o-rings are easy to remove with a pick, but finding the correct o-rings took me a while, and when I did find them, I could not get the inner most one to seat, so I got a Dorman fuel line repair kit that has the o-rings installed, and I tried to cut the line, and repair it, but I learned the fuel line tool I bought could not crimp onto a curved line, so in the end I just bought some fuel injector hose, and a clamp, then I removed the plastic hold down clip from the fuel rail, and ran the hose from there back to the passenger side firewall, where the nylon fuel line meets the metal fuel lines.
I'll see if I can find the part number that I found that was actually the right o rings if you want to tackle the job yourself.
I tried to ask a local dealership about buying the o-rings, or replacing them for me, but they said they would have to replace the whole fuel line, because you cannot safely replace the o-rings, so they would not sell me the o-rings, I guess they just wanted to make more money, because I have heard of others that were able to replace theirs.
Here is a pic of mine when it was occasionally leaking, I expect it was doing so when I'd hit bumps in the road..

Well the car won't start but I took off the vacuum line that connects to the FPR and fuel did leak out. I snapped some photos of other parts where fuel is leaking specifically in one part which I do not know what it is called so I will need your guys help identifying it. Here are the photos:

I tried to snap the shot of the fuel coming out but I couldn't but there was fuel that leaked out of there.

Whoops! I just saw there was a specific Bonneville sub forum.
How difficult is it changing it? If it'* fairly easy I'll give it a tackle but if it'* too difficult I might get my local mechanic to do it. Is is just pulling it out (from what i've read it seems so but it'll give me a bit of a struggle) and putting the FPR in place? Thanks a lot guys, you have been a great help.

It'* a piece of cake. Just need a set of snap-ring pliers and a new part. Pop the snap ring out, pull the top off, pull the diaphragm out, put new one in, and voila!

Well I changed the FPR and it stopped the leaking but the car still does not start. We tried to jump start the car but it didn't do anything. Any chance that the engine locked up because of all the leaking?

Define doesn't start? Is the engine turning over? If so, then we need to find out if the engine is getting fuel and spark next.
