This is from my 4 year build post
Pictures in the origional document.
If you guys are doing a engine swap and need to change your fuel system to efi and surge tank try this.
I drilled a 25mm hole in the bottom of the tank then built a tin dish to suit the profile of the tank installed a fuel pick up and drain plug in it then tig welded it on.
I also used the fuel tank liner kit resin type to seal any pin holes in it. The returne line is the stock one and the original fuel feed line has been capped off.
By doing this it keeps every thing standard in the car. And the serge tank is about 2 litres.
