I made significant progress on my trunk area this week. I have the meth system 100% done and all the fuel system bits in the trunk finished. After getting all the AN hardware and 5/16 soft lines hooked up I had a friend come over to help me flush the system. We powered up the car's electrical system to test the new electronics, wiring, the in-tank walbro and the feed/return lines to the main tank. To begin with, we ran fuel into the surge tank until it was 100% full. Once the surge tank was totally full we forced gas to low backwards through the -6 return line and into an old gas tank by kinking the return line between the surge tank and the main gas tank. After a gallon of fuel went through the -6 line I used a set of vice grips to pinch off the end of the SS fuel pump return and focused on the A1000 pump / -10 side of things.

As I posted previously, the stock fuel pump controller has been totally disabled and the Walbro always sees 100% voltage directly from the battery when the ignition is on. I placed a manual shutoff switch in the trunk to prevent the A1000 from running during fuel system maintenance which really came in handy while I was trying to test and flush the fuel system. Since the surge tank was full from the previous testing and flushing that we had done I directed my friend to place the engine side of the -10 line deep into a large gas can while I powered up the A1000. I must say, I was very very surprised to hear how the A1000 sounded. I was expecting a very smooth noise similar to the Walbro (only louder) but the A1000 sounded pretty crazy. I would liken it to the noise the Hydramist pump makes when its running only much much louder. We decided to run two to three gallons of fuel through the system while I carefully monitored the A1000 to make sure that the surge tank never ran dry. I felt pretty good when the A1000 was not able to drain the surge tank after one minute of 100% flow. I also played with the fuel pump controller a bit and and experimented with the high and low settings.

As I previously posted, I am going to use the Hydra to control the A1000's controller so that the pump will switch between a high and low setting as needed. I am very happy with my decision to spend the extra money for the Aeromotive fuel pump controller because it cuts the pump noise by 60-70% at the low speed (when compared to 100%). Make no mistake about it, the A1000 pump is loud, very loud when running at 100% duty. One of my next projects will be to wire in the connection between the fuel pump controller and the Hydra. I will also need to setup a map to get an output to ground out while under boost. I plan on posting very detailed instructions on this as soon as I get it finished and working.

Here are a few crappy cell phone picts of the final product:
