Question about Cars & Trucks
I am working on a 3.1 liter buick regal that is pouring raw fuel out of the throttle body, i suspected the fuel regulator to be the problem, i have a new regulator ready to install but upon removing the intake manifold there were some fuel lines under the manifold that lead up to the throttle body, those fuel lines are hard and brittle and fell apart when i lifted the manifold off, i should have taken a picture or marked the lines but who would have known they would have broken the way they did, could someone please let me know how to route the lines so i can put the car back together and find out if the regulator fixes the car? i am an experienced technician but this is the first time i have worked on a 3.1 liter regal.

SOURCE: fuel pressure regulator
unfotunately all of the throttle body and sometimes the intake has to be removed to do this, what is really great (just kidding) is you also have to remove these things to replace a $2.98 PCV valve, because the fitting for the top of the valve butts up against the top of the intake, so BE SURE to do that at the same time, just a tip..

SOURCE: Spark plug pattern
the spark plugs shouldnt make a difference the wires are what make a difference and if they are all different lengths then the shortest wire will be for the closest spark plug.

SOURCE: fuel lines
You have the lines crossed. One is pressure from the tank, and the other is the return for the unused fuel to return to the tank. Newer models do not have this, but yours does.
Switch the lines.

The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.

I did this job on my 3.1 about 2 months ago and i forgot to put the ("O") ring on back fuel rail. had a fuel mess!! had to tear down plenum to fix, in my case i lost the o ring on rail and forgot to put 1 on. I had to order 1 from chevy garage, and replaced it. cost 9.00 just for 1 little o ring. mine fit tight also!! see if o ring is ok, and check line. car runs fine!!
