Hey rceron

Here are some photos to help with my explanation of the fuel system. These two show a top-down view of the fuel cell, and a forward-looking view of the external surge tank from underneath the rear of the car, respectively. Note the fuel pumps and line routing on the fuel cell.

Here are two top-down views of the surge tank (a little offset from eachother). Note the line routing here.

There are three lines to the top of the surge tank - the bottom-most rubber line in the photo is the output line from the dual pumps; the top-most rubber line is the factory fuel return line; and the braided line is the return line to the fuel cell.

There is another line which you can only really see in the second photo - this is the output line from the main pump, which draws from the bottom of the surge tank. This is the factory fuel supply line, which you would simply re-route from the OEM fuel pump. In the third photo, you can see the main pump to the right of the surge tank, and its input line running to the bottom of the surge tank.

At the bottom-center of this photo, you can see the top of the main pump and its output line more clearly. Notice that it simply runs forward to the factory fuel supply hard line. Here you can also clearly see the factory fuel return line running back to the top of the surge tank (the line that crosses in front of the main pump output line).

Referring back to the top-down view of the fuel cell, you can see the dual pumps mounted at either side of the top of the cell.

The input line for each of these pumps runs through the fuel cell plate and down to one of the two corner pickups. As I explained previously, there is a corner pickup at both of the rear corners of the cell.

The output lines from the dual pumps are teed together, and the resulting single output line runs to the top of the surge tank.

The return line from the top of the surge tank simply runs to the fuel cell plate, where it dumps the return back into the cell.

I forgot to mention one other thing...

A simple modification you can make to the cell to assist in fuel scavenging is to alter the bottom to make the rear corners the lowest points in the cell. A hammer can do this job quite effectively, as well as putting a slight rearward tilt on the entire cell when mounting it.

Thanks for going out of your way to do this. Need sometime to absorb and digest. Suspect I'll have questions.

Thanks again.
