Currenly, $80K for a "roller." Constructed to Ford's original engineering blueprints. 90+% of the parts will interchange with the 1960's original.
This is not a kit car. Unless you are experienced and able at race-car engineering and construction, you should have somebody else do the installation.
Go to
SPF MK2 Fuel system
and look at the images and read through the thread. If you are familiar with these types of decisions and installations, then you may be able to do the deed yourself.
A Lynn Miner on this forum is doing his own installation. You will see a posting of his on the above web page.
