[Diy_efi] schematic critique (now gas tank drawing)

[Toyota Supra]

ok, you'll have to forgive this sad drawing, hopefully this helps make 
sense, i don't have photoshop here

here is the link http://68.7.7.84:8080/schematics/tankcomparison1.bmp

a) yes, there is two of them

b) no, there is not

c) no, but there is no out of tank pump

d) not sure what you mean, both pumps have pickup filters on them



let me know what you think, thanks
