Don’t worry too much about it. Leave the port open to atmosphere, set the fuel pressure and run it. K.I.S.S. It not need be overly complicated. And I wouldn’t choose the deadhead style over what you have. Other than for testing of course.
Well, I had it set for 6
Got on it and it dropped to 2, so something ain't right
I agree the return style should be better, that's why I swapped out the deadhead in the first place..
But it seems like a good way to troubleshoot it now
