Parts added and LOWERED Prices
Part: LSJ 2.0 stock exhaust manifold - NOT AVAILABLE, will use it for a turbo conversion
Description: This manifold is the factory part that came from a 2006 Cobalt SS/supercharged. Reason for selling is because it was replaced with a GMPP exhaust manifold. The manifold has about 12k miles on it.
Part: stock ss/sc pulley,stock belt and stock intake manifold gasket used for 12K miles
Description: belt and pulley from 2.0LSJ 2006 supercharged.
NOT AVAILABLE
Part:Stock LSJ Air box
Description:Air box from LSJ 2.0 with 12k miles. Replaced with fujita CAI.
Price: $35 + shipping

Part: Stock LSJ fuel pump
Description: In tank stock LSJ fuel pump.
Price:$40 shipped

Part: Cobalt Boost Gauge
Description: Aftermarket Cobalt boost gauge up to 30 Hg@vacuum and 30 psi. Bought it from Ljavyy17. I think I'm not going too far on boost. Going up to 20~21psi. Still in box and didn't installed it.
Price: $160 shipped

Parts needed
1. Walbro GSS342 - longer than stock fuel pump
2. Aeromotive A1000-6 Part# 13109 regulates from 30-70psi
3. Fuel lines (20 -25ft)
4. fittings
5. fuel filter (1 input, 1 output)
Step 1
Take out the tank. Several bolts need to be unscrewed. Try to have an almost empty tank. It'll weight less.
Step 2
Take out the module inside the tank. Be careful to take out the cap where the fuel pump is located. It has like 4 clips. Use a philips screw driver.
Step 3
Take the stock fuel pump out. Take out the in-tank regulator.
Step 4
Insert Walbro GSS342. Warning, this fuel pump does not fit in the location where to stock pump is located. Put back the cap and tied firmly with 3 straps.
Step 5
Replace one of the fuel lines that goes into the tank with a fuel line. This one goes from the tank to the bottom of the regulator. You gotta be extremely careful here, try not to break the plastic fuel input of the module inside the tank.
Step 6
Installed regulator.
Step 7
Here you got two choices. Either buy a 2002 Ecotec fuel rail, which is already tapped, or tapped the stock fuel rail, that's what I did. Connect a fuel line from the side of the regulator to where the fuel rail is tapped. You'll know where to tapped because the fuel rail the LSJ uses is the same as the cavalier except the LSJ's is blocked. Drill and connect fitting.
Step 8 Verify for leaks and connect vacuum hose. You have to get a T, cut one of the vacuum lines and install. Replace the fuel filter. It needs a 1 input, 1 output type and be aware of the flow directions.
Step 9 Test for leaks. Switch to Run until the pump fills the fuel line. You'll here a small whine and when the fuel pump stops. Remember, you have to do this everytime you start the car. The regulator does not hold fuels in the lines like the intank regulator.
Step 10 Use a wideband to setup the fuel pressure. Set the pressure. Try to set it for 40-41 psi. At vacuum should be 50-51psi.
After the installation, I went to a dyno and set AFR to 10.8. Dyno results after return style and fujita CAI. The KR I got before the return-style, gone.

To prevent starvation of the fuel injectors to the farthest of the fuel rail where the fuel lines enter. On a return fuel system, there is a constant fuel pressure inside the rail which means that the fuel injectors are basically getting a equal amount of fuel. On a return-less fuel system, the farthest injectors might not get as much fuel as say the closer ones would.
This can directly affect the performance of that one cylinder (I believe #4). A wideband would show your a/f overall, so if you richen, you'd be richening your total a/f but that doesn't mean that #4 injector would be getting the equal amount of fuel and it could cause that one cylinder to detonate from being lean.
The SRT-4 guys do this change when they are looking into a big horsepower application (I believe they suggest anything over 400 HP that you do this).
