fuel probs
 

Hi all i am building a nitro air boat and i have noticed that a lot of the builds have the fuel tank level / in line with the carb
but on the life size boats the fuel tanks are lower down

what i would like to know is are there any low voltage nitro fuel pumps out there that i could use
as i don't have enough back pressure on the manifold to get the pressure that i need
i am using a tiger 40 engine which is 4" above the fuel tank
help please
