Weekly update time.
Been doing a bit of everything to start getting the shell fitted up .
Fuel tank.
After some head scratching (a few months ago) I decided not to use an original style tank , but fit a fuel cell inside the boot. Ideally it would be sunk down through the boot floor to get the weight lower down in the car, but for the time being I'll set it on top of the floor and change it later if I feel like it .
Reasons to use a fuel cell:
a) Almost cheaper than a reproduction tank , straps, sender, filler neck , etc
b) easy to connect to - AN fittings already on there
c) already comes with anti-slosh foam and baffling inside, and a rollover-safe breather with ball valve.
I was going to fit a swirl pot as well, to eliminate any possibility of fuel starvation - but it may not be necessary, and the swirl pot (and second pump) would be extra weight and complexity.
Summit 20 gallon cell will just about fit through the boot aperture, and should be big enough for up to an hour's racing.

Needs a few modifications though:
1) The sender unit supplied is very poor quality, and is held in with self-tappers (aargh horrible). Quality VDO cylindrical senders are available in a whole range of heights, and happily the bolt pattern is the same. I drilled out the self-tapper holes and fitted M5 countersunk rivnuts . Much nicer now.

2) Got some mounting tabs welded to the lower sides.
3) Since the cell is inside the boot, regs dictate that the filler must have a spill tray that drains to the outside. Bent up a strip of ally and had it welded on, with a 10mm drain tube as well. Also - the filler neck is plastic and not great quality - I replaced the washers under the fixing nuts with larger ones, to reduce the distortion already present.
