Bosch 400lph fuel pump??

[interex]

Would a Bosch 400/lph inline pump be a good way to go for my engine build (check profile).

I really dont want to go with 2 walbros, or a walbro, and then another inline.

Why not just sump your tank and just run a Weldon or Aeromotive pump if you want some serious flow.

I am at this same point as the original poster, and I will most likely be going with an aeromotive pump. There is really no reason not to, your going to need a bigger feed line than OEM, so you might as well go with an A1000 or larger.

The Bosch 044 will easily outperform the Aeromotive pumps, IN DSM APPLICATIONS.

At lower fuel pressures the Aeromotive will outflow the Bosch pump by quite a bit. But decently high HP DSM's do not flow at low fuel pressure. If boost pressure were to be around 30 PSI, I would expect fuel pressure to be around (30 + 43 PSI) 73 PSI.

At 73 PSI of fuel pressure, this is where the Bosch begins to shine and the Aeromotive falls on it's face. The Bosch flows well into the 90 PSI range while the Aeromotive is already out of breathe at 75PSI+.

Bosch 044 is the way to go.
