Couple of fuel system related questions Options

[CelicaB]

Trying to get a celica back on the road, does anyone know what size this fitting is? It's the one that goes into the bottom of the stock fuel filter.



Also does anyone have a wiring diagram for the stock fuel pump and it's plug, or at least what each wire color does? Car is a 94 GT





Thanks in advance!!

the big blue wire is fuel pump pos+
white with black is fuel pump neg. (it's just bad lighting)

y/b 12v pos
br 12v neg
y/r fuel level variable voltage.



y/b and y/r may be switched can't tell just from the colors, but if its wired like a pot, thats the order it would be.

Thank you!!
Fixed one wire color in case someone else can use this info in the future. Also found a pretty good pic of the stock pump and sending unit.
