Mix fuel pump sizes in dual boost activated setup silly question
any problems mixing sizes ?
lets say i have a 255 and plan to run a 400 activated via hobbs switch with boost , the smaller Fuel pump will give up against the bigger one??
mix 255 with a 340? 400? or twin 255s?
i dont want to heat up fuel by using too much unused pressure bc is a street car
power goals is 700-750rwhp on 80 pounders

Not an issue with return style fueling. Unless you are boosting pump voltage and jacked up pressure it won't get hot enough to matter.
Honestly I think mismatched pumps will create some turbulence and reversion at the connection. Both of those will create more heat, reduce flow, and wear the pumps faster.
How much boost in psi and where's the redline? What fuel are you running? You'll need these to use fuel flow calculators. Personally I like to cross reference ID and DW online calculators.
