I have one walbro in tank but i am thinking about adding the bosch inline or just go all out on the pump.So the bosch gets my vote.

So from my understanding you will tap out at the bosch limit ...
Please correct me, if I'm wrong

^ I believe you're correct. I would also worry about surge issues into the Bosch if there's no surge tank since the walbro should be able to out flow the Bosch. My brain doesn't like the idea of trying to force in more fuel than the pumps capacity to flow, but then again I'm kinda retarded sometimes. At least with a surge tank there's an over flow ability and will be zero head pressure on the in tank or inlet of the in line

i was under the impression a surge tank is needed if your intank fuel pump can keep up with your inline pump thus causing your inline fuel pump to work harder and strain itself. the flow will be restricted to what the walbro 400 can make but the pressure will be greater at the same flow rate due to the bosch 044 inline,
surge tanks are only needed if fuel starvation or lots of lateral car movement is made in my understanding

... i used to use this setup , i have since went back to dual intank setup as the noise the 044 makes after its broken in is unbearable .. when they get hot they tend to sound like a coffee grinder .. if you use a surge tank it tends to mitigate some of the noise why not look into the aem 320lph pumps and do a simple twin intank setup .. i have researched them to death and they have less then 1% failure rate and its 100% e85 useable ..

^^^^^^ this is spot on , is called head pressure ... i used to use this setup , i have since went back to dual intank setup as the noise the 044 makes after its broken in is unbearable .. when they get hot they tend to sound like a coffee grinder .. if you use a surge tank it tends to mitigate some of the noise
