Are these pumps suitable for external mounting?

I'd probably find it a lot easier to mount a dual outside the car and run lines down into the tank than sumping the tank or creating some sort of dual mount in-tank. I know the gas acts as a radiator for the pump; are there any other problems I should be aware of with this configuration? I don't care about pump noise, just getting ideas at this point. Thanks

 

in short, no.
they are designed to be submerged. if not they will overheat and fail faster than normal.

 

Thank you!
