Probably GPH! That is how my Holly pump is rated.

Be careful of using some types of electric pumps with tanks that have a
syphon feed out the top. I found that my Holly pump likes a constant
feed of fuel and the priming action required to get the fuel from the
tank to the pump is too much to get the fuel started. So I had to
modify the Spitfire 1500 tank to a resemble the gravity feed Mk1 tank
that it replaced. Worked fine after that. (Albeit, very noisy).
