Hey there Johnny
I got the aeromotive a1000 pump and regulator .Now do I run my return line from the aeromotive regulator or from the fitech return ? If you have a diagram I would appreciate it a lot .
Thanks again . moparisbest
Below is a diagram for an inline fuel pump, with a return line.
in your instance you have two options...you can leave the regulator inline (say to 60 PSI) and still run the return through the fitech.
OR
you can set the regulator to 58psi, and run your return from there, and then plug the return on the fitech.
in the diagram below, note that there is no external regulator. the fitech can regulate itself to 58psi if the return line is utilized, HOWEVER...i have heard of, but never first hand seen, "big" efi pumps "overpower" the internal regulator. I've only heard of this third party.
also some of those aeromotive regulators are return style only...you can't plug the "return port" because thats how they regulate. if thats what you have, then regulate it at the regulator, and just run a dead-head line to the fitech.
