After taking what felt like one million years to drain the tank I removed it and started on the surge tank and second fuel pump. I think there was 16 gallons in the car, seriously it took forever. Put all the fuel in my otehr two cars lol.

First I gatherered everything up and got an idea of what was needed as far as space goes. I wanted to preserve as much of the trunk space as possible. Cheap chinese surge tank, check. External Walbro loud ass pump, check. And some AN fittings.

My original layout idea.

It's so dirty under there. I still need to drop the rear end so I can remove the factory hardlines and build new 3/8" stainless stuff.

I cut a piece of steel to be tacked to the floor of the trunk to give myself a flat surface to build on, It is my hope when this is fully enclosed that should there be a minor fuel leak it will go out the bottom of the car along with any fire lol. Not sure how that's going to work out. Hopefully I'll never find out. The rason the plate doesn't extend to the blue line is that I felt it was too big for no reason.

This was option 1

Option 2

I'll more than likely go with option two. I'll also more than likely cut the angle stuff on a 45 at the corners. I'm hoping to find a piece of scrap aluminium somewhere to build the top out of so the enclosure doesn't weigh anymore than it needs to. Called it quits for the night after this cause I was tired of it to be honest. Also i need to order some fittings to get final clearances for the enclosure. For those not familiar with surge tanks, it goes like this. In tank pump keeps the the surge tank full. External pump takes fuel from the surge tank and sends it to the engine. Pretty simple way to get rid of the fuel pick up problem on FC chassis while turning left. There's pretty much no condition under which the main pump won't keep the surge tank full enough to keep the second pump feeding the engine.
