External fuel pump for fuel cell?

[ajfeik]

What are guys running for an external fuel pump for their fuel cells if it doesn't already have an internal pump?
Or are most desert guys running an internal pump for simplicity?

Thanks in advance guys

In a desert racing environment, in tank pumps are desirable because they run cooler submerged in the cell than they would if mounted externally, minimizing chances of vapor lock. Also, it has has been has been my experience that fuel pumps are happier "pushing" the fuel from within the tank, rather than "sucking" fuel from outside the tank.

Perfect response and absolutely spot on! Eg...run an external fuel pump up high and...DNF. All that nice cool fuel with the fuel pump submerged at the bottom, makes for happy fuel delivery. My 2 pesos
