1988 F150 rear tank. Which line is the supply line and return line? I have one that is blue and the other is white.

Usually the supply line is bigger on most vehicles.

That could be possible. See which one has the fuel filter on it. That one is the supply line smilietease

Unless Bill Corrects me there is NO mention of colour in the lines on the parts list.

Just that they are made of nylon and one has a straight connerctor and the other has a 90* connector

Here is the illustration that I hope helps you

Thanks Dennis that really Helps... smilieFordlogo

Do you happen to have from the fuel filter forward to the engine? My fuel system is really butchered up. I want to put it back to the way it came from the factory. Thanks again

Blue is supply, the gray would be return, and they actually are one size off... 3/8" for supply, 5/16" for return. Also, as mentioned, one will be straight, one will be 90 degree.
