Depends on how much fuel u need supply. And if u want it in-tank or external .
External pumps allow more choice but becomes expensive with swirl pots extra fuel lines etc. Plus you lose boot space and car smells of petrol not to mention the noise
I think the best thing might be 2 HP walbro pumps that will fit in tank just adapt the hanger .
The two high power walbro pumps cost around 90 quid each and together should supply more than enough fuel at half the cost of other motorsport pumps,Bosch o44, areomotive , hks etc.
