dual bosch 044's in series
dual bosch 044's in series I'm shooting for 800-900whp and i already have a bosch 044 in the system. I want to add another for my new setup and was wondering if two 044's in series running at the same time would do the trick. I want to stay away from a parallel system and hobbs switches. I want to keep it simple and not pay $40 for a couple y blocks. Thanks.

Running them in series would be totally pointless.
If you need flow, they must be in parallel. I just run mine all the time, and have done for about 5 years...maybe even 6 years.
And you dont need a Y-block. A simple tee piece works just fine. A Y may be nicer though

I ran both of mine off a single 30A fuse and single relay. Means if there is a problem with either, both pumps will stop, so there is no risk to the engine.
Under most circumstances, they seem to draw around 22A
I used -8 lines from both pumps, into a -8 tee then onwards to the engine via -8
My tank to pump side is not ideal, as I only had a single outlet on my tank, so just used a single Aeromotive 100mic filter when then tee'd -10 into each pump.
I will upgrade this over the winter though.
But again, it has ran totally fine like this for the last few years.

Stevie is correct!! I see about 11-13 amps at 72 psi and upwards of 18 amps each, when the filter is dirty. When the filter is really dirty, the PDM is tripped at 20 amps, and I run the car on the reserve pump. I monitor filter life based off pump amperage. 
But most cars dont have a Motec PDM 
Those pumps are great, youll really like them. They are very very durable.

Thanks for all the info guys i liked the single bosch 044 on my 5.3 so I'm sure I'll like two even better. I have two outlets on my fuel cell so I'll run a pump from both outlets then t it off and send it to the fuel fails. This system should support atleast 1000hp correct?
