'96 Park Avenue lost vacuum hose

[danielcrenteria]

I live in travis county,aka Austin texas and i can't seem to pass the emissions test for inspection.I believe one is a short circuit in the purge valve.Im just gonna go ahead and buy a new one.Another problem is ,as you can see..i have a vacuum leak that is attached to the fuel rail.Idk where i can get a hose for that.Next,in one photo i put up.theres a hose at the bottom(aside from the green connector)I absolutely no idea where it came from or where it goes.any help will be appreciated ...

The main component in your pics is the fuel pressure regulator FPR - the small 3/4 inch tube at the top does connect to the intake manifold to provide vacuum. When the vacuum changes it varies the amount of fuel pressure on the rail.

Check out this diagram - item #516 - http://parts.nalleygmc.com/showAssembly.aspx?ukey_assembly=368691&ukey_make=1022&ukey_model=14446&modelYear=1996&ukey_category=19398&ukey_trimLevel=15566&searchString=vacuum

any idea on where that other lost vacuum goes too?The FPR i already know i just need a new fitting but the thing is where can i get that one exact piece?

As far as the "other" vacuum hose is concerned I can not make out from the pics which one you are talking about. Perhaps someone else can see it and can provide additional info. If you give us a little more detail maybe we can make it out.


Regarding the FPR vacuum tube - if you go back to the provided link - scroll down and you'll see item #516 listed below - it provides the actual part number, description, and price. If you want to buy it from them just call the number on the website and I'm sure they'll sell you one.

I did some additional searches and it looks like this part is not widely available. Good luck and let us know how it goes.


Some more pics from different angles might give us a better view.

thanks....but its starting to be a pain!i can't figure where it goes or where it when.I think looking at someone else park avenue or le sabre would help!

You may have to get some plastic elbows & vacuum hose from your local parts store and make up some new connections. Since you have an L36 (VIN-K) engine, the diagram below will give you a better idea where each hose/tube in connected.

thanks for the reply..So i went to a junk yard and found the line i needed..Still my question is answered .That bottom hose thats not attached to anything can't be found..I even seen at the junk yard,it was either a PA or lesabre and it had the same hose just there with nothing attached to it..Im still having codes also.Ugh emissions suck!
