Well I redid my fuel system over the past 3 days thinking it would help my fuel starvation problem. It made it a little bettter but didn't cure it. I'd think 200 needles would let enough fuel in, but it seems they don't unless what did can't supply enough fuel for the motor (I doubt that). Looks like I need to invest in some 300s.
Any way on to the fun part. This is all done on my 2g but it'll be similar for a carbed 3g except that the 3g has its pump in the tank. You 3gezers also luck out not haveing to pull the tank down to get the pickup out, though you might want to take the tank down to make it easier to run new lines. Now find a lap to sit in cause its story time.
This is the old 2g pickup, The 3g part looks nothing like this.

Then I bent up a piece of 3/8" steel tubeing to sort of resemble the original tube.

If you're wondering why go to all this trouble, here's the diference in the pipes.

Then cut the old tube off and drilled the hole out to fit the new tubing, got out my welder and did a really bad job of welding the new tube on. I managed to set the connector for the fuel gague on fire 2 times as well.

I had to trim it up a little bit to get it into the tank. I also tossed a coat of paint on the top (don't paint the part that goes into the tank). Once it was all dry I put the tank back together and bolted it back up.
With the tank in place I tossed the old 2g prelude pump I was useing, and replaced it with this nice holley red. (The stock pump was on the frame rail next to the tank. This one is on the spare tire well, it was too big to ever fit where the stock one was. Stock 3g pumps are in the tank.)

Next I ran some 3/8" soft tubing up to the motor. Soft tubing is so much easier to work with but takes twice the room of hard lines. That was boreing so I didn't take any pictures.
Then I mounted the holley regualtor that sean (formerly known as funstick) had given me when he helped me with my trans. Spliced in my fuel gague and fired up the pump.

Once I got the regualtor figrured out, didn't have the spring in right after cleaning it, the pressure stayed at a steady 4psi. It held 4psi when the motor was running and when it was floored. Thats alot better then the old pump which was at 2.5psi (2-3psi is spec for the pump), but fell to 2psi when the motor was running at 2000 rpm and fell to barely 1psi as soon as it was floored. I can now get about 1/2 way though 2nd gear, depening on how much I let the tires spin when I shift, before it runs out of fuel which is a little better then running out of fuel just as I shift as it was before.
