[T3] fuel pump output -error

[Keith Park]

Yes, and the addition of your backflow valve seemed to achieve the same
thing whey I was running the 2056 with the stock T3 pump and Green 2L
injectors.

Now that  I've had a bit more time to think about this, I can imagine 
very short  extreme times when the flow from one pump might not be 
enough for a big  engine. To make this work, you'd want to put the 2 
pumps in parallel. Are  you sure Ray put them in series?





I think Ray is using 1 pump as a "lifting" pump (like a rabbit has), and  
the other pump is the main supply pump. What he's doing, by doing this, is
to 
 ensure that fuel delivery isn't an issue with his closely tuned t-4 engine 
 (where pressure deviations of 2 psi can cause a lean condition). He's been 
 playing with it for years, and found fuel delivery to be a problem (using 
the  stock pump).
