Based on pitlanes testing I thought 280 would be the requirement for an intank pump, but getting a bit off topic, is the standard fuel reg and return up to the increased fuel supply of an 044? Dont want an unstable rail pressure making a good tune almost impossible.

Heaps of info found on intank pump upgrades, Pitlanes pump testing thread is gold! What I cant seem to find is the crossover point of an intank pump, which I have, to requiring a surge/044? This is a very grey area I know but was hoping some new data may be available like pitlanes on the standard pump.

Thanks for the great replies, Benny I am assuming always maintained 1/2 tank as I like many others have experienced fuel cut prior to finding this info. Since Ratter made it known supply is also marginal (low return flow from rail on his testing) well, get out the wallet. I personally do want my fuel system legal which is why I like the KPM module and somehow missed the KPM460, so this is the type of product I am after. Thanks for the quick and detailed responses.

Hi all, am still uncertain what option to go with for safe fuel supply at only 300rwkw. There is lots of great info on fg fuel surge/cut at under 1/3 tank. Obviously the 044 and swirl is the most common solution although do not want pump noise inside car as I know it will piss me after a while. Can it be heard at idle or above? Love the new KPM intank but for only 300kw seems like major overkill. Does anyone know if installing a walbro or similar intank pump will just improve fuel flow in l/hr or do these pumps sit a little different in tank and not suck air as easily? Im guessing not but worth asking to save a grand. Cheers
