Exit into FPR inlet. Other inlet plugged. Return line to tank.
I know this is not the best way to do it but wondering if the way I have it set up will cause any issues? This was just the easiest and cleanest looking. Thanks for your input.
First time I've heard of it. LOL trying to learn as I go. I will have to spend a little time with Google and figure out exactly what boost referencing is.
Boost reference means connect your regulator to the lower manifold so it sees boost/vacuum. You definitely want to do this as it keeps injector size constant with vacuum and boost. That silver hose fitting pointing down, connect that to the manifold after the throttle body and update your tuner on what all youve change

It will be a hell of an update.
I am running a surge tank fed by stock pump to 2 450 e85 pumps. My plan was to pull out the stock FPR (now I'm not sure it has one might be FPCM controlled) but not sure what I removed. I will wire 1st 450 into factory pump signal (using hotwire kit) so it runs with factory pump and 2nd pump to a hobbs switch. Do I need to disable the FPCM similar to this? https://www.performancetrucks.net/fo...-power-547334/
or do I leave that alone so tuner can just set factory pump to run all out all the time?
This is the thing I thought might be a fuel pressure regulator. I removed it along with stock fuel filter. Last couple of pics https://www.performancetrucks.net/fo...-549168/page6/
I assume running boos reference does not change how the pumps are wired?
alternatively, some with a good fuel system/injectors will run static 58-65 psi for a KISS method.
I'm undecided, which is why I'm asking/paying devils advocate...I hope it sparks some conversation that could help us both decide
There is zero advantage to that. The only reason to run an unreferenced regulator is if it is far away and would not be pratical to tie it in. This is the case with "returnless" systems. The name is a misnomer as there is a return, it is just inside the tank so you dont see it.
With boost, it is very important and beneficial to reference it, or you will have to massively oversize your injectors.
