Yeah I was not thin king about the return line pressure being nothing.

The bosch pumps are external and very quite.

I just read the whole thing and lots of good info guys. Who sels this Bosch pump I like to know if needed in the future.

5yrs later and still great information - just wanted to say thanks to all who contributed. Given me some useful tips on changes I need to make.

Old thread I know, but I am doing EFI now and there seems to be a lot of conflicting theories.

At a relatively low power level (500-550), from the sound of this thread I should be able to put the reg on the rail as it enters with a T to the other rail and it would only be deadheaded the length of the rail itself. Does this sound like a good compromise?
