Bosch 044 Alternating Noise Issue


Active Member
Hi all,
Please find my issue below:

Power input to the pump is constant along with my AFR`s with them not changing inline with the pitch change on the pump.

Setup is i have another 044 in the tank, feeding the swirl pot, then the other 044 being fed from the swirlpot to the engine.

Anyone have any idea if this is normal?

It drives excellently with afr`s stable at high loading,

Cheers in advance,
