I bought one of those aeromotive 340 pump for an upgrade on my walbro 255. I was thinking is it possible to run both of these pump on a Dual hanger? I know the flow Is mismatch but can it be done? Don't just want to toss the 255 pump in storage so why not just use it too.

 

Why didn't you just get dual Wally's? You shouldn't mismatch flow rates. It doesn't begin to sound like a good idea.

 

I wasn't Really planning but was wondering if Mis match flow can work..

 

I don't think that would be such a good idea because the voltage/current characteristics of the pumps is different. Due to their unique requirements, you might be running one of these pumps at a lower flow rate to even out the supply voltage.

Personally, I wouldn't do it.
