I am needing to up grade my fuel system and was ready to buy this new tank but the fitting size has me wondering. 6-an seems to small. I have searched this forum and others and the general opion is that your fuel line size is only as big as your smallest restriction. Meaning if I run a 10-an line I am still restricted to the 6-an that is at the pump. I have a 850hp bbc carb. I know the pump is big enough but I would think I would need a 10-an line. My only other options are a custom tank from Rick's with an A-1000 pump which would be great but twice the cost. I know you have to pay to play! What do you think?
