That will work ok.
As a side note, "deadhead" regulator's (1 line in, 1 line out) are very marginal at doing what they are supposed to do, especially, low pressure ones.
If you want to check this, mount a fuel pressure gauge OUTSIDE the car but where you can see it while driving.
It will read up and down like a tachometer, with engine speed. The pressure will sometimes drop to zero at full throttle on a long steep hill pull.
People buy this type regulator because they are cheap.
The alternative is the bypass type regulator which has a return line to the tank. Not cheap but quality never is.
