My 02 Z is getting a head/cam package as we speak as well as some other goodies like a new clutch. I tried to find the part number for the fuel filter on my car but couldn't find it. Anyone have it available so I can get it from GMPARTS Direct?
Also, I am going fairly streetable with a 228/232 113 LSA cam, etc. but I believe my installer/tuner is going to use the stock injectors, is this safe?
Brian,
Sorry but don't have the GM part number, but it is available from AMSOIL as part GF336. This fuel filter is for the rail mounted fuel filters in mid-2003 and earlier Z06s.
- Relieve the pressure in the fuel line at the rail. - Disconnect the battery. - Raise the rear of the car, best done from the rear subframe. - IF you have an A4 space it tight and it helps if you remove the catback portion of the exhaust on the drivers side. - The filter is just up under the frame in front of the drivers side rear wheel - Remove the bolt holding the filter assembly to the frame. - This is where it gets messy... Remove the two quick connect fittings towards the rear of the filter, just squeeze the blueish colored tabs and pull the two lines from the rear side of the filter. DO NOT be right under this - a couple of cups of gas will come pouring out - trust me I got soaked... - Using the fuel-line disconnect tool, remove the line on the front side of the filter. This is tight, I was worried about snapping the line when I did mine but it will come out... Again, some gas will pour out and remember the filter itself is full. You MUST use the fuel-line disconnect tool here. The tool is made of metal or plastc and looks like a ring with a cutout and tail that slide between the connector on the line and the hard tab on the filter. Same tool is used if you ever remove the line from the fuel rail...it's the 5/16" one. - Clean up all of the fuel that went everywhere. - Put the new filter in place and bolt it down. - Reconnect the lines. - Reconnect the battery. - Turn the key in the ignition to pressurize the lines but do not start. Do this two or three times. - Check for leaks. - Replace the catback if you remove. - Lower the rear of the car. - Take it for a spin. Note: I made some small additions but the majority of this tip was posted by someone else but somehow it got deleted from the database. If I could remember the original author I would've made reference to him. Thanks
You can possibly have 2 different fuel filters, depending on what type of fuel system that you have.
If you have one stainless steel braided fuel line going to the engine, then you have the 10299146, which has a fuel pressure regulator built inside it. List is 54.28
If you have 2 stainless steel braided fuel lines, then 10287788 is your filter. This does NOT have a pressure regulator built in, and is $13.70 list.
Mid year 2003's and up with FFS Fuel System the fuel filter is in the tank and not necessary to change.

Brian,
I responded to your email with specific info.
AMSOIL lists the GF336 as applicable to 1999-2003 C5/Z06 Vettes. This one should be the fuel filter/pressure regulator.
My 2002 Corvette Service Manaul shows the fuel filter/pressure regulator to have only one line running to the engine.
AMSOIL lists the GF341 as applicable to 1998 and prior C5s and this should be just a filter (and the one that has two lines running to the engine as described by IT L GO above).
Price for the GF336 is notably less than the GM part price quoted above. I found this same thing with Ford. I could get the fuel filter for my F350 from AMSOIL at about 60% of what Ford sells it for. If anyone would like the price of the GF336, you can either email or PM me, or click on the AMSOIL Online Store and type gf336 in the search box to the right.
One more quick question guys. I checked under the hood this a.m. before work and noticed that there is one stainless line from the firewall to the center of the driver's valve cover. That is the line correct?
Brian,
That line does carry fuel from the stainless line that runs to the firewall to the fuel injector rack. The actual fuel filter is way in the back of the car up under the drivers side frame rail. A stainless line runs forward from the fuel filter to the firewall and then to the line you are looking at.
As IT L GO said, for an 02 Z06, you either need the GM 10299146, which has a fuel pressure regulator built inside it, list is $54.28, or the AMSOIL GF336.

So the dual lines are near the fuel filter and not going into the engine area?
Brian,
Not having an older C5 that has the dual lines, I don't really know how they terminate at the fuel injector rails. The older style had two lines coming forward out of the fuel filter and going forward. I think the second line was a return line which helped regulate pressure, but I'm not sure.
A 2002 Z06 has one line running forward from the fuel filter along the frame rail up to the fire wall and then to the braided line you saw that runs to the fuel injector rack.
Part number for this should be GM 10299146 (or the AMSOIL GF336).
Update: After putting everyone through misery etc. I called my local Chevy dealer and gave them the last 8 numbers of my VIN#. They can tell what is on it from that! Thanks for everyone's assistance.
FYI.. the dealer wanted $67.14 and I got it from GM Parts Direct for $30+.
