I've just spent quite some time tinkering with a heat shield to isolate the early V11 Sport fuel pump from the left hand cylinder radiated heat. After all the messing about trying to get it right, I thought I'd share the details for the final successful (Mark V)iteration, in case anyone fancies getting it right first time. I used 0.5 mm Aluminium Sheet cut and drilled to the shape in the attached .pdf template (should be overall 165mm x 180mm if the scale is right). I then covered with adhesive heat shield fabric - I obtained mine from ThermalVelocity.co.uk (other suppliers are available). It will protect against radiated heat from the cylinder but not convected heat from the engine. If used in conjunction with a manual fuel petcock (GU01105460) see Gutsibits, changing out the solenoid one, and a properly burped fuel line, this should by some accounts purge my vapour lock gremlins, without having to relocate the pump and fuel filter. We'll see whether it works, if we get a real hot summer - dream on...! Andy Heatshield_template.pdf
