No seperate and/or additional gravity feeding if thats what you mean.
Return line from regulator still goes back directly into the fuel tank close to wwhere the feed pump picks up the fuel from the tank. Upper connection on catch can goes back to tank as overflow and also acts as a breather. Pics of the set-up are on page 33: http://www.germanlook.net/forums/sho...t=9953&page=33 The idea of mine is/was that a zero-pressure feed pump (which is now the 944 pump) always supplies more fuel then the high pressure pump will be able to flow at 45 or 60 psi. |

Hi Wally
The reason that I asked what sort of pump you were using to feed the surge tank / swirl pot is that myself and a friend both had noise and heat issues when using EFI type pumps to fill the surge tank / swirl pot. My friends pump actually failed. We put it down to cavitation in the pump as it was not restricted with a pressure regulator etc as it would usually be in a EFI set up. We are both using Carter lift pumps now. Obviously your car has travelled many kilometres using a pump this way, but it maybe something to consider. Steve

Thanks for the info Steve! I would feel better having a dedicated large-volume, low-psi feed pump for this tbh.
I never could find anything for this. Hmm, worth looking into Carter pumps (never heard of them before). |

That could be I didn't see where the lines went to

More header pics at the import site. They are WRX this time so a bit more relevent. Divided housing, but incorrect cylinder pairing

He just did not kept the single wastegate divided, which he should and that is indeed a BIG mistake. Might as well kept it simple and 4 int 1 then. |

Hehe, there's been a misunderstanding, I was reffering to 70Turbobug's post about seeing a race car with 2 separate inlets from the tank to the catch can, and it has nothing to do with your electrical pump problem :P

Right you are. I was viewing on a small netbook screen.

http://www.summitracing.com/parts/CRT-P4600HP/ This is the one I have been using to feed my surge tank. It seems to work well and haven't had any issues yet. I had some noise from it but it was caused but not mounting it properly and the body of the pump was touching some steel, giving off some vibration. I also have a small bleed line of 3/16" coming from my surge tank and tees into the return line. This ensures that I do not build up pressure in the surge tank. Mike

You're probably right Mike, so I 'won' me a 100 gph one from evilbay. Hope it gets here soon.
In the meantime, I figured this turbo needs a bit smaller A/R for this little engine and it came in today: 0.91 instead of 1.00 A/R: Just looks as big as the other one |

Downsizing is cool these days
