Fuel Supply - Complete

I fitted a couple of stainless P-Clips to the supply and return hoses that fit to the bulkhead fittings in the boot to satisfy the requirements of the IVA.

I was concerned about the smell of fuel in the boot of the car, along with the garage so I did some research online and came up with the following: 

• Standard rubber fuel hoses won't leak fuel, however the fumes will pass through them.  For this reason, PTFE lined hoses need to be used to prevent this.  I used Goodridge 811 Series PTFE hose. 
• The fuel tank requires to be vented for the filling and emptying of the tank in normal operation.  This basically means that the fuel tank is open to the atmosphere and therefore vents into your garage when the vehicle is at rest.  Normal production cars have systems that feed the fuel tank vents back into the engine through an emissions control system.  Since this is far too complicated to do, I chose a different method.
• I found a two way valve from Newton Equipment Ltd (TPV8) that states that the valve remains closed when the engine is switched off, therefore preventing fuel smells in the garage.  The valve allows the fuel tank to breath when both filling and emptying and can be mounted in any orientation.

I mounted the Newton valve inside the N/S rear footwell as high up as it could be mounted.  Hopefully this will clear the tyre!  This involved drilling a hole through from the boot and using some P-Clips to mount the valve.  On the outlet of the valve I fitted a standard fuel filter just more as a dirt filter to prevent dirt being sucked into the tank.  I used stainless jubilee clips with hose end covers.  I sealed the hose exit using some sealant to prevent water ingress.

Before fitting the tank and making up the last of the fuel hoses from the pumps, I covered the tank and boot in Silent Coat sound deadening pads.  These make a huge difference to the resonance of the fibreglass and the stainless fuel tank.  I really went to town with it, maybe a bit too much, but I didn't want to have steps in the carpet once it was laid.  I did the boot floor, wheel arches, rear bulkhead, main seating area, engine bulkhead and under the dashboard.  It has added a good bit of weight!

Once the fuel tank was in position, I cut the fuel pump wires to length and crimped the ends.  This will all require clipping into place, but I will wait until I finalise the rest of the boot lights.

The wiring harness from the pumps was run through the passenger footwell and clipped using P-Clips.  The heateed seat wiring was also joined in with the run.  This wiring will be covered with tape prior to the carpets being glued in position.
