Necessity.
You want the fuel to pour into the fuel cell without adding pressure to the return line.

I have a piece of tubing inside the cell so the return is below the surface of the fuel. Keeps it from causing bubbles that could be pulled into the fuel pump.

This............I didn`t but will ad an extension tube to the cell and run it down into the foam to help stop aeration and foaming.
I ditched the foam years ago. I have a tube on the returns. I two returns, have one from the pump and one from the regulators.

I'd be curious to see how that works, maybe it's time for a Mr. Wizard test.

If you are running foam in the tank, you don't need to run a tube in to it ( or below the fuel level in the tank ) to eliminate fuel airation. More important is NO back pressure. Try not to run a 90* fitting in to the tank. The fuel traveling through the foam ( plus the prefilter )will insure a solid stream to the pump.

I have foam in my cell and the only sharp 90 I have is the line that goes to my fuel pressure gauge.

I threaded a fitting and did this on my Duster.

Won't submerging the return line into the gas already in the tank increase the return line pressure?
I know it makes a big difference on my water tanks at the job site, I have to keep the hose out of the water in the tank I'm filling or the flow really slows down.

Your talking inches of water back pressure(about 30" of water to 1 psi)... with the return down in the fuel it reduces aireation a ton... but if the return is far enough away or if it has foam there isnt any problem

I removed my foam years ago because of the alcohol in pump gas with zero issues. These are the instruction that came with my BG400 pump.
Bypass The return line should be fed with a single #8 or 1/2" line. Plumbing kit number 150187 is avail- able for this application. The return should expel the bypassed fuel into the liquid rather than into the air space of the fuel cell. This will prevent aeration of the fuel. All fuel tanks and cells should have fuel cell foam installed to prevent fuel slosh. WARNING: DO NOT BLOCK THE RE- TURN, VENT, OR PUMP FEED. MAKE SURE THAT THE SYSTEM IS LEAK FREE AT ALL CONNECTIONS...YOUR SAFETY DEPENDS ON IT! Wiring BEFORE MAKING ELECTRICAL CON- NECTIONS, DISCONNECT THE POSITIVE TERMINAL FROM THE BATTERY. Your BG400 Fuel system should be connected to a fully charged 12 or 16 volt battery. A fuel pump, like any other electrical accessory, will only perform at its best when given adequate voltage. The black wire is a ground (-) and the remaining wire is a switched hot lead from a 12 or 16 volt source. If wired incorrectly, the pump wi

I know sometimes I'm a bit out in left field, but I have thought about this before. like in a fish tank where water flows out of the filter and dumps into the water, its adding oxygen to the water, is it possible that when fuel is dumping into a fuel cell, is it adding oxygen to the fuel similar to some race fuels that are oxygenated
