Fuel Cell:
Fuel pumps are not pretty and quite noisy so they were put inside the tanks.
There is one Scavenge pump and one pressure pump in each tank, each tank
feeding one bank of 6 cylinders. The fuel tank is 1.2 mm aluminum with 4 mm
of polyethylene inside. Rotational
Molding was used to melt the plastics into each alloy shell. Foam was
then put in each tank and the pumps were installed. There is a fuel gauge
sender in the left cell. Drive by wire & throttle bodies were removed
and replaced with 325i parts.
Dash Pod:
The gauges from a Miata are used with a custom pod covering them. The mechanical
speedometer is driven by a motor which gets it's info from a computer which
gets its signal from the right rear half shaft. The oil pressure and tempeture
sensors are Miata items. The Tachometer signal is reduced by 33% to be accurate.
