Its a very simpe design:

1. After emptying the contents throughly use a pair of diagnal cutter to carefullt unroll the crimp in the metal can cap.

2. Pull the cap out.

3. Get some aerotrend 1 1/8" OD coupler cut a 1" piece.

4. Get a pressure fitting and install it at the end of the curve in the front of the MCP.

5. Cut 1 1/2" off the end of your header pipe.

6. Put the 1" piece of coupler in the MCP. It will be a bit of work but it will go in.

7. Lube the inside of the couple and the 1 1/2" piece of header with fuel and slide the header piece in to the coupler. It my take a few tries but you should end up with 1/2" of coupler and pipe in the MCP.

It should look like this:
