Truck sat for five years and now will not take any gas in either tank. I dropped rear tank and there is a blue vent thing on top of tank. I do not know what it is called. I have a Chilton manual but cannot find where all vent lines go.

Hello,

Make sure none of the vent hoses are kinked or bent to where air cannot get through.

Here is a video on how to remove a fuel tank so you can see how the vent hoses go on a normal tank:

Below are some diagrams of how the lines should go our your truck.

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
