My cheap fuel system 1 stock tank= free
vette regulator= $45
Walbro pump
05 mustang gt filter= $5
hand full of compression fittings I had laying around= free
roll of Summit 3/8" fuel line= $30
3" license plate recess box from suicidedoors.com= $15
drill some holes in the license plate box around the bottom of the sides, tac weld it to the bottom of the factorytank, run some hose connected to the vent tubes in the factory tank and direct it into a 3/8 hose size hole in the side of the box and clamp it, connect return line from vette regulator to 5/16" vent tube, now the return line feeds the makeshift sump too
pretty easy and dirt cheap fix to the non sumped tank issue if you ask me
also a lot easier than building an internal sump from scratch

I'll get some pics up later, I just took some of the box, the vent tube, and the location I mounted the pump, filter, regulator above the rear end housing
The license plate boxes are folded up but the corners aren't welded, this creates a taper that allows fuel to come in/out more easily towards the top of the box, but it gets tighter and tighter down to the bottom.
For my needs it will do just fine and I seriously doubt I'll have any starvation issues unless the tank is almost bone dry. Best part is the pump is easy to get to and unless you look close everything appears stock. No hanging sump or fuel tank, no hole in the trunk floor, and it would be easy to go back to a mechanical pump (not that I ever will).

But doesn't that have to come after the pump? Plus that thing costs $45...I'd rather replace a $5 filter every other oil change than let that one get clogged. I also thought it would be a good idea to filter before the pump so it doesn't burn up prematurely.
I have a habit of getting bad gas so I want it to be as easy as possible keeping everything good.

running a tight filter as a pre-filter is a bad idea, it puts too much restriction on the inlet side of the pump. That said, yes, you do need some type of filter on the inlet.

you need a filter that is designed for the suction side of a pump. it will be around 75 or 100 micron. usually this is handled by the mesh "sock" on the inlet of the pump when its in the tank.
