I have been reading a lot about this stuff. Here is what I have come up with so far:

Larger fuel line
Put the pump below and close to the gas tank to act as a pusher and not a puller
Additive (may help a bit)

What else?

What does a larger fuel line help with? What ois the point to this?

Why run the FASS system instead of a standard pump closer to the tank? I can remount an LP close to the tank with no problems. Do I want a pump that can flow more GPH?

Thanks
