Dont know the full specs, but this i know!
GU Sub tank pumps are a transfer pump not a delivery pump.
the pump in the main tank delivery fuel to the engine bay at the required pressure, the sub tank pump is less in pressure.
I found this out when i bought my GU dual fuel wagon and wondered why the gu went crap on fuel ( no top end ) after talking to the gas mob that done the conversion they told me that when the main tank comes out for the gas bottle you loose the large pump from the system and have to rely on the sub tank for petrol
