My tank design for project PJ

OK here is my tank design.

It uses plates in the lower portion that extent leaving a 1" gap at the end.
These plates are staggered so that if the tank has 1/4 of fuel or so it can still run on its side.

If the jeep is on its nose I would only need a minimum of fuel in the lowest chamber to keep it running.

If the jeep was laying on its rear I would need the lower 2 chambers of fuel.

If it was on laying on the drivers side I would only need the lower 2 chambers of fuel.

If it was on the passenger side I would only need the lower 3 chambers
side

rear


There are baffles in the upper portion that simply strengthen the tank.



Here is what it would look like in the frame


Because the plates will not allow flow between them I could not have a float that ran up between them. The solution was simple I plan on making these(or buying if I can find some that are threaded at the ends).



The design is simple the plastic ball(white). Pushes against a cylinder(green) that makes contact with a connection(yellow in the back) there is a spring(not pictured) that keeps the ball from pushing back unless there is fluid pushing on the ball.


Once the cylinder makes a connection a LED on the dash will lite up showing that level of fuel.

These would screw into the back(of the tank so they could be easily removed if they fail or if I need to flush out the tank).

I plan on using the FATS system. http://www.pirate4x4.com/forum/showthread.php?p=2712471


Having the tank be sealed and the vapor tube be at the highest point in the filler neck before going up and along the tube frame before coming down into this little canister.

It would sit inside the frame rails held in via a strap and have a fluid in line indicator(same design as in the tank) that would let me know if there was fluid in the line. At which point I would simply turn the little screw at the bottom and drain the Fats canister.

After the canister I have the vapor line going to a charcoal canister (located where the battery is now) and then the manifold.

What I am wondering is how to run the return system. I plan on using a truck avenger so I think I need to use a return line off the manual pump. What I don't know is where the best spot to put the return line in the tank would be.
I want to put the return line up front along the top portion(inside the driver side frame rail) this would let the fuel run along the (empty)baffle section cooling it before it fell into the lower portion. Does the pump have enough omph to push it up 4 inches(tank height) above the frame?
Should I use a 3 way filter and where should I put it? Still have a lot of time and these are minor thing still I would like to get the fuel system checked off my list.

Give feedback on this design also I am kind of one sides at this point.

 

since there is no restriction in the return line it should not matter. The preassure from the pump will be more than sufficent to return the fuel to the tank.

 

Thank you, that covers the return line pressure issue. If I used a 3 way fuel filter would the fuel return to the tank(recirculating from the filter to the tank to prevent vapor lock) from the filter or would I need to mount the filter level with the tank's filter(return)hole? So I would have 2 holes at the front of the tank one for the filter and one for the pump return.
