Just for buster :)

The Skyline fuel tank has a good design to keep fuel pooled around the internal fuel pump, fine for nearly all uses. However, around a racetrack typically on a hard left hand corner combined with a low fuel level, the 'In-Tank pump' can starve of fuel. The result is a sudden drop in fuel pressure to the injectors, followed by instant engine hesitation and leanout - not good !

What you can do is an external fuel swirl pot as this will solve the problem - an extra reservoir of fuel that sits between the pre pump and main pump. Using the Skyline in-tank pump as normal, the pot should keep itself well primed, hence no real need to have the return injector rail line feed into the pot as well, just leave it alone to return normally back to the fuel tank. Without the extra swirlpot, the only way to avoid a potential drop in fuel pressure on hard left hand corners is to have the tank well over 1/3 full. ( a cheaper option most will say )

Ok so not the best document but hey what do you expect its 12:30 and I want a pint !
