I am not surprised you are feeling the pinch David, any half decent turbo has got to be worth at the very least £20,000 of anybody's money, and you will get poorer with the resulting increase in fuel consumption. Here's a tip for you from my Indie, who did his apprenticeship at PCGB. The fuel tank on the 996 T, notwithstanding its Ron Weasley (measly) 15 gallon capacity, is a sort of saddle tank construction because of the front diff. As a result they are susceptible to the pump pick up sucking vapour if you try to eke too much out of the tank before filling up. It has been known for a minimally fuelled 996T to exhibit the symptoms of running out of fuel whilst negotiating steeper inclines. Inevitably this damages the pump, because it is lubricated by the fuel. I guess the warning to "condsider the range on the remaining fuel" is there for a reason eh? The fuel flowing through what is probably a roller type pump, like most fuel injected cars, damps out the sparks on the commutator of the DC motor too. Luckily, the vapour in the tank when the pumps does suck vapour is an order of magnitude above the upper explosive limit, so there is no risk of a fire, in my considered theoretical opinon. Comments invited as to whether this seems like so much B/S, but how else do you explain the lack of tank fires?
