95 Aurora intake manifold help...

[5acresohio]

Hi all. I need to know the name of the part on the opposite end of the intake manifold pictured here. When looking at the pic I'm talking about the right side. Is this a replaceable part or does it come as part of a new intake? This is where my intake manifold is leaking. Any diagrams or detailed pics would be great if anyone has any.

i'm going to try to help (with an emphases on "try")
I think the part your talking about is called the "FUEL PRESS RLF VALVE"

mind you this is for a 97, was called the same thing for a 95, but changed on 96's (i'm guessing fuel line recall)
and with new steel rails (recall fix) is no longer needed
and caped off like mine!
(sorry about the pic quality but it was COLD outside)


now i'm going to try to confuse you............LOL

and listed as part 547 in the diagram, for a 95




at this site it states... "(WHEN REPLACING MANIFOLD, CUSTOMER MAY NEED TO REPLACE THE PRESSURE REGULATOR VACUUM TUBE W/12558023 & CAP OFF PORTS WITH NEW MANIFOLD USING CAPS)" as does RockAuto (where i got the part # for the intake!

i hunted down part #12558023 and came up with:

www.compnine.com/index.php?name=12558023
said price was $6.43.

but when i go to the diagram for a 97
i get a price of $35.69 for the same part, and states
"VALVE,FUEL PRESS RLF(PART OF 534 intake)"
www.compnine.com/index.php?u=1&year=1997&artnbr=3M00-015&artsfx=NULL&supplgroup=80&catcode=35G&modelcode=G&makecode=O&modelseries=GA&uid=1&modelid=1147577364&capuid=1&majorgroup=00&grouptype=B

i'm really not sure if you can buy this part separate from the intake, i can't find it at any GM parts source other then this one!
sorry! you may want to get intouch with them.

some options for ya, might be if you can't find the part:

A two part epoxy to seal the leak (as this part is no longer needed,with the fuel rail fix and is just caped off)

A new intake $279.79 from rockauto (forget that)!


or a bone yard part?

Nice work Tipsymcstager. I might add this from the Caddy Forum.
I could'nt find any replacement parts for this "over pressurization
relief valve" anywhere either. Here is part of the discussion with
some pics:

[5acresohio]

YEAH!! Thank you so very much!! My car is running again. I have found it to be called 2 different things...backfire relief pressure valve or fuel pressure relief valve. That part is a discontinued part here in Springfield Ohio so we just sealed it back up. Worked and we're back on the road. Thanks again...
