Re: Fass and regulated return
Here's a tip....
The Fass I had, had a pre set regulator of some sort in it's system built in. Then when you run a RR system with a conventional fuel regulator the two fight one another or create a imbalance. You have to swap out a springs to bump the Fass pressure to a higher pressure to get it to run-up against the RR system regulator as it's last in the fuel circuit .
However you do it make sure you have only one source of fuel pressure regulation.
