I figured i would share this with everyone, and since i am a newbie on here i am posting it here. I have owned and worked on dsm's for quite some time just never got into these forums.

Before you attempt to do any of this make sure your tank is empty and has sat and aired out for a few days!!!

This is my stock 1G fuel tank that i fabbed up a custom sump for. I found that the sump kits you can buy from summit were way too big for the dsm fuel tank.

I started with finding a good spot on the tank then figured out the size of the sump I wanted to make, it is 8" long X 6" wide X 2" tall, i used 16th" thick steel a little thick but what i had on lying around. I marked out on the tank where i wanted it to go then I took a hole saw and drilled 1" 1/4 holes within the area where the sump is going rater than just cutting the whole section out, thus leaving the structural integrity of the tank and creating a baffle. Sorry did not get any pics of the baffle.

The next thing I did was weld up the sump then weld it on, make sure you clean the area to bare metal really good! You want to face the deep side of the sump the part where your fittings will be toward the rear of the car that way when you launch the fuel will be pushed into the lines rater than away, avoiding fuel starvation.

I still have not drilled the hole in the sump for my weld-in bung for the fuel feed line, you can do this before the assembly of the sump. My return line is going into the tank where the fuel sending unit and stock fuel pump goes. I made a plate that replaces that since mine was real rusted. I used aluminum, it will have a AN fitting in it. I integrated my stock fuel level sender into my plate i made as well so i still have a fuel level gauge.

This is just the beginning of my build and the custom things i will be doing! More to come!
