Here is where the fuel cell sits.  It extends well below the factory floor level into where the stock tank would be.  It is also centered in the car, the  tank on a stock car is centered  twards the drivers side.

Here is the fuel cell in place, there are 2 stock fuel pumps run in paralell for added volume and redundancy.  It also has an inline fuel filter on each line and just down stream of hte pumps are 1-way valves to hold pressure in the lines.

This is the areodynamic fuel cell shield. It is very effective at smoothly directing the air past it at high speed.  Dave tole me Team Toyota protested this shield as an unfair advantage, but it was allowed to stay.

This is the 22 gallon fuel cell.  It is made of plastic with the aluminum top made to securely bolt it into the frame.  It has dual pickups and a vapor breather on the top.  the vapor breather has 2 float balls to keep the fuel in the cell if it gets turned upside down.  The car was built for 150 mile races so it neeed a large fuel tank.

Here is where the ECU sits. It is an 87 ECU, I'll be putting in an 88 ECU so I can raise the boost past 14 PSI. The canister below is the oil accumulator, it collects oil when the system is pressurized and releases under pressure if there is an engine failure or low pressure condition  It also acts as a resovoir making it an 8 quart system with out having to change the oil pan.
