87 gas tanks
ok my 87 has dual tanks and the guy i bought it from said the rear tank has had gas in it for 6 years. so i sifened it out. now i am wondering if i just put new gas in it will it work just like new or should i pull it and clean the whole inside? and 1 more question. my gas gauge doesnt work. and when i turn on my key the gauge just goes past full all the way it can go. i was thinking it is the sending unit. but im not much of a mechanic so can you please help me.

These trucks have a habit of needing fuel sending units. It's a common problem, mine goes past full until it gets to about a quarter tank and then starts to bounce towards empty. If the rear tank has had gas in it for 6 years then I doubt the fuel pump works in it.

fuel gauge
the gauge going to full could also mean the float on the fuel pump/sending unit is not attached, or working. drop the tank, pull out the fuel pump unit and look at it. couple of hours work.
