fuel pressure guage
 

i juss got a electronic fuel pressure guage... its second hand with no

instructions... but i know how to connect it i juss dont know if the supra has a

fuel pressure sensor or something.... cuz the guage has the white(light) black

(ground) red(positive/acc) and purple (goes to sensor).... so is there a sensor?

sumbody???

I dont think there is one all you have it you fuel pressure regulator which runs on vacuum

You would have to get the correct sensor for that gauge, what brand is it?

After you get that then you could put a T somewhere, I guess before the FPR, and put the sensor there.
