They do offer an inline 255lph walbro. Could you add a 044 close to the tank while using stock lines?

i opted to use a bosch pump because of the much higher base fuel pressure that can be run (~150psi max pressure versus ~80psi of a walbro), and the fact that walbros have some reliability issues with them (when on low fuel)
you also have to look at the fuel system in 2 ways, do you want hi pressure or hi volume...
the FB setup is a hi volume setup and low pressure (maxing out around ~80psi total pressure) so to achieve big numbers you need low base fuel pressure, thus needing large (2000cc) injectors to drive the injector duty cycle value down into a tolerable level....
The Bosch setup like mine is Hi pressure, letting one use smaller injectors (1000cc) but running higher base fuel pressure , which drives the duty cycle value way down.....
i still may run 2000cc injectors to make sure i dont ever run out of fuel, or maybe add another bosch to the surge tank......

You know all we need is someone to start making a new hanger with an Bosch 044 which would be a great solution.

Apparently the tops are different in the dbw ones. Hit me up and we will make one that fits. LJ

I know a DSM guy who did dual Walbros on a budget and did his DIY fuel pump hanger in 2 pieces/brackets that he put in individually and then screwed together.

You can mod the walbro to run past 80psi. We have done it over and over without any issues.
