What color wire is for the sending unit for the fuel level guage at the tank. I am stumped.

yel-wht fuel sender with single tank and dual tank.

All I have is an orange, black, red and blue with a yellow stripe

What size engine do you have?

300 straight six (or 4.9)

According to my manual I have a red-wht for front tank. I imagine red with a white stripe. A dk-blu-yel for rear tank.
Send me a private email with an email address and I will scan you a copy.

Thank you. I have a dark blue with a yellow stripe.:biggrin:
