Fuel Pump placement

Mine is roughly 6" from the center top. I'm thinking it might be just a smidgen high. I only have 160 miles on the it but haven't had any problems yet.

I'm thinking about moving it further forward and down the the rail to get it further away from the exhaust and lower it so it won't struggle to pull gas out of the tank.

I filled up after the engine swap and drove 77 miles. Then filled up to see what gas mileage was (8.75 mpg). Then drove another 80 miles and filled up again, exactly 10 mpg this time.

So...I haven't driven with the tank very empty and have wondered if the height might cause problems with an empty tank.
