An easy job turned into a hard one. Trying to get the fuel tank out of a 47 cab I have for parts. Passenger side seat bracket has some square tab welded in so I can't get the bottom of the seat out. Also, I don't know what this part is, I believe it is what is holding the tank on still. Anyone know what I need to take this out?

 

Alright false alarm. It can be undone from a 9/16 socket. I never knew of such a thing. Looks as if a cotter pin is supposed to go into the bolt. Thanks for the help... Ha

 

Looks like a castellated nut to me. Can you get at the bolt head under the truck? It might be a two person job unless you have really long arms.

 

If I recall correctly, that is a stud welded to the bracket, not a carriage bolt so you should be able to remove it with out the bolt spinning. Just give it a little with PB Blaster or something that to help ease it off.

 

I have all the nuts removed and the filler pipe for the tank. I am still hung on something. Is there a bolt and nut under the cab? I try lifting the tank out but it feels like something in the center is holding it on. I am stumped cause this is my "parts" cab and I have no room or way to tip it over and look under it.

 

Did you disconnect the fuel line that went to the engine?

 

Fuel line? WOW! Same time 38!

 

Sometimes great minds think alike....

 

I will post a picture tomorrow of what I am talking about. To dark at the moment. Maybe the cab is lying all of its weight on the line?

 

Sorry I forgot to post the updates. Got the tank out. Some wrong parts on it made it hard to get off. Plus when I shake it I hear a piece moving in it. Probably a rock or bolt. Needles to say, I don't think I will use it for a spare or backup. I will check the tank on the other truck. If that becomes a problem I may just fabricate a new one in the frame rail.
