Hello, All Is A A1000 fuelpump too big for a single 525HP 502 carb. I plan on running 1/2 supply and 1/2 return line , does anyone know where to get a good deal on the marine grade blue fuel line and what make. I need about 38 feet. Thanks Alec

that pump works great and is fine as long as you run a return system to the tank

I,ve got a good used one. I upgraded when I rebuilt my blower motor.

im running 2 a1000's on 2 500efis, i am running number 12 from tank to[inlet strainer] pump, then #10 from pump to fuel filter then to fuelrail then number 6 from regulator to fuel filler neck for a return. works perfect

get an extra relay or-2 they are the weak link !

The Fuel Pump Will Work Ok . You Will Need To Run A Return Style Fuel Regulator With A Fuel Return Line Back To Tank. Do You Want C.g. Aproved Fuel Hose Or Performance Fuel Hose. We Have Parker Bleu C.g. Aproved Hose (big $$$) And We Also Have Other Marine Fuel Hose And Performance Fuel Hose.

Is the Parker hose approved for pressurized fuel, ie between the pump and carb?

yes it cg aproved for high pressure, but still expensive,we have other alternatives.
