I've seen a lot of people using the bosch 44 inline pump but no one seems to be using the 40 intank. My walbro is either going, or is just not up to the task, so I'm looking at the bosch 40 which flows 300 lph. I know people are going to say, us both the walbro intank and the bosch 44 inline, but I really don't want to deal with the noise of the inline pump. My neighbor has a bosch inline and I can hear it from across the street.

below is the specs and write up I found for the bosch 40.

i have that same in tank bosh but i also have a 044 inline.works much better then the walbro/044 combo that most use.

i dont think youll make any where near the clamed 700hp on the 040 alone
