We used brass ballpeen hammer + brass drift punch to get the locking collar off, same deal to put it back on. ( make sure all the tabs are slid under their mating tabs). Brass used, so no sparks. We also tied string to the assy, so stuff would not fall back into the tank. It's a trick getting the pump assy out, since it's a tight fit.
Shine a light into the tank, and u will see the crap floating around at the bottom of the tank on driver's side. In an ideal world, you would do this with a 1/4 tank of gas....and suck out some of that crap that's floating around the bottom of the tank. We didn't, just cleaned the sock filter. My sock filter had 3 x rubber bumper's on the base of the sock..which sits on the very bottom of the tank. So the sock filter is sitting just above the bottom of the metal tank.
The back seat comes out in 10 secs flat. Mine had pull tabs dead center, between ur legs. We removed the entire back seat via the pass side, with pass side seat slid forward as much as possible, and back seat folded towards windshield, and pass headrest fully nested.
Ok, when you get pump + sock re-installed, and locking ring back on, you have to prime the pump. Procedure is to put key to 'on' position ( eng off)..for a few secs. You will hear the pump running+ purging air. Shut key of for 2 secs, then back to 'on' position again. You will hear the pump once more. Do that 2-6 times, till you no longer hear the pump noise. At that point the pump is primed, and you can just fire the eng up.
In 'on' position (eng off), let the aeroforce gauges boot up. ( have em pre set to read both fuel rail pressure + also FPDC (fuel pump duty cycle). Once booted up, you will see that the fuel rail pressure is aprx 50-53 psi. Turn eng on, and pressure will drop down to it's normal 40 psi. Take it out for a rip, and you will see that pressure stays put at 40 psi....and FPDC will be a lot lower.
Aeroforce gauges ( anything plugged into OBD port) will indicate exactly 1/2 of real FPDC. IE: '40' = 80%. My aeroforce reads '18' at 750 rpm idle...and ...'39-40' at 6.1 k rpm. 36-80% fpdc.
