Dont use a t-fitting; use a y-block.

Here is a quote from kiggly on the topic:
"scaling for multiple pumps is extremely dependent on the fitting that merges the pump flows. A long time ago I was running a "T" fitting and two pumps in parallel barely flowed more than a single with this restriction."

Interesting. I'd like to see more info on that if you have a good link.

I ask because I am running two 255's, in parrallel, with a "T" fitting, on E85, airflow right around 60lb/min, still on stock wiring, and haven't ran out of pump. I have a pretty solid 11.2 AFR until redline. If it really barely flowed more then a single pump, I would imagine I would have ran outta pump awhile ago considering I'm running E85, and also have not rewired them with thicker gauge wiring.
