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!!

Don't have the wiring diagram with me since i'm at work, but just looking at the plug most likely:

the big blue wire is fuel pump pos+
gray fuel pump neg.

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.
