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?

Aeromotive recommends...

Read up on Aeromotive's instructions. My understanding is with EFI and high pressure, say 45 psi and up, the delivery capacity is ample at -6AN fuel line. With lower pressure, using a regulator, Aeromotive recommends upping the line size to -8AN. For serious horsepower, they recommend a bypass style plumbing arrangement, using a fuel log at the carb.

The Aeromotive Stealth 340 is an extremely capable pump.

I talked to aeromotive tech today. Motor makes 850hp on gas.
One Pro Systems dominator. Complete fuel system will be new.
I just think the 6-an outlet will be a restriction. My last car had a
Mega fuel 500 with 12-an to pump and filter then 10-an to reg.
New system will be bypass style. Thanks
