How far has everyone gone with their fuel system upgrades. I shall be running the intank pump but not sure if I should upgrade this.. It will then be going to a swirl pot in the boot, or is this overkill? Then to the Bosch 044 inline mounted under the car, Then a racing fuel filter To the fuel rail, As its schimmel manifold it's has an adjustable fpr in the engine bay, with an inline pressure gauge. Finally back to the tank, Is this over kill for my vrt?
