[RL18]

Okay lets take one huge step back. First off I'm assuming from looking at the new pump in the pic that the new pump is the r90 pump (upgraded pump) the old pump is the stock pump aka r70 pump. So if you have the r90 pump follow this: I put some marking on your pump pictures. So lets look at the old pump you have...

The white marking is the hp side connection going to the fuel rail.

The blue is the return line connection.

The red is the supply line connection.

Now On the new pump...

The white marked connection is the same

The red marked line is the same

The BLUE line is the banjo bolt connection. This banjo bolt won't connect to the new fitting provided on the new style r90 pump. So you follow that line till you find where it "tees" off, at that tee you pull that yellow plastic line completely off. You then take your new 3/8 fuel line, put your clamp on, push it onto that tee and tighten the clamp. Then you go to the pump and push the hose onto the blue marked fitting (the new pump picture) and tighten the clamp. Now you are completely connected
