1/4 inch minimum is the way to go , The cost difference for material is minimal. I’d insert an extra bung for an extra pickup so one pickup is Main other is reserve. One thing I’ve learned with fuel gauges on boats during my 50 years is their worthless when you drop below a 1/4 tank.
Piece of mind to know you have 15-20 in the tank if you run out on the main pickup.

There have been a handful of times since buying our PQ that we have come into the ramp on pucker, thinking we were sucking fumes. During our ongoing rebuild, while addressing the tank pickup sitch, I called Florida Marine Tanks and came to discover we have a 90gal tank, when I was thoroughly of the opinion it was around 60gal, and that the fuel gage sender is a 12" unit, which only reaches the bottom of the "square" portion of the tank. Anything below that, that which reaches into the vee of the hull, below the bottom of the square sides of the tank, is out of sender, which he said was good for about at least 15, maybe 20gal. We have 15-20gal of fuel when the gauge reads empty. Go figure.....
Thanks. Brad.

The return to filter is the less desirable way to do it. Returning to tank is always better and allows you to use the entire cell as a cooler. If you don't have access to the tank or dont want to risk drilling you can always dump the return in the fuel fill neck, usually 1-1/2"

I remember when you first came on the site and excited about your new flat deck. Next thing we know you’re cutting up the floor, at the time I thought to myself what a rude awakening to buying a big expensive Hole in the wallet.
Whoops you did it again .
