Gas tank removal?

Hello,

My gas tank is becoming my worst nightmare, i am going to have to take it off to have a closer look at the hole in it. Has anyone ever taken a 1st gen gas tank off? I have an 83' if that helps at all. Do you think chiltons repair manual will cover this?

Thanks alot,

CD

Getting above the gas tank to remove the fuel lines is a real pain. It's alot easier to remove the gas tank when the bed is off. Plus,you can inspect the lines and your sending unit and replace them alot easier if they need to be replaced. Chilton will cover the gas tank removal, too.

Re: Gas tank removal?

Just a suggestion, but if your tank is leaking your better off just replacing it instead of trying to fix the old one....won't be long and you'll probaly spring another leak somewhere else on it, and your back at square one. The peace of mind is worth the cost of a new tank imo.

Re: Gas tank removal?

hmm I never thought I would have to remove the bed, I suppose I should buy the chilton repair manual for the bed removal as well. Ill keep you updated.

Re: Gas tank removal?

bed removal is easy. 6 bolts (possibly 8) and u can see exactly where they are if u crawl underneath. then u have to remove 3 bolts outta the filler neck (inside gas door) and the harness for the taillights in the back, should be somewhere around the back of the driver side framerail. then get a buddy or 2 and pull the box off.

Re: Gas tank removal?

You don't have to even lift the bed off the truck, just remove the bolts on the driver's side of the truck and loosen the ones on the passenger side and tilt it up:


While I have it lifted up, I have someone shove a jackstand between the bed and frame to hold it up. Plenty of room to to get the fuel sending unit. I have replaced over a dozen fuel pumps myself. Last year the fuel pump went out in my S10 and it took my bud and I thirty five minutes start to finish to swap it out. I had to replace my tank his past fall due to rust pin holes. I patched it with Permatex radiator/gas tank epoxy and that bought me about half a year. Ended up buying a plastic gas tank through JC Whitney so that I never have to worry about rust again. Two tips:

1. If you get another tank, you will need to get a new fuel sending unit lock ring or cam. It's the metal ring that holds the fuel sending unit in the tank. Some part stores carry them in the "help" section. If you can't find one, you will have to go the "stealership" part number is #251-24032 and the price will be around $5. When you install that new lock ring, GREASE the living snot out of it so that it doesn't rust to pieces like to old one did. When I put my new tank in last fall, the lock ring still looked brand new and it came right out with no problems.

2. If you have a full tank of gas like I did when I had to replace my tank, you've got a problem. You need to get all that gas out. The easiest way to do it is first disconnect the fuel lines. Do yourself a BIG favor and draw a picture and/or label the lines so that you remember where they go. Connect a short length of hose to the outlet side of the pump which will be the line closest to the cab. Run the other end of the line into a gas can(s). Then disconnect the wiring harness that goes to the fuel pump. Take a jumper wire and connect one end to the positive terminal on your battery and touch the other end to one of the leads in the plug (there are two) on the fuel pump and it will pump all the gas out. It goes lots quicker than you think it would. Only took me about three minutes to pump out nineteen gallons of gas. HTH's

Re: Gas tank removal?

there is 4 bolts on the outside of the frame that hold the gas tank in ,
if you remove the bolts the whole gas tank assembly will lower down,
remove lines and pull out from under the truck,
then you can remove the straps from around the tank , when it is out from under the truck
in the picture above with the bed tilted( is a great idea also), you can see the upper bracket that the straps go to, that is part of the assembly that will come out when you undo the fore mentioned bolts.

Re: Gas tank removal?

when i did mine i dropped my tank and then extended the rubber hoses another foot and a half which made it much easier to install afterwards, i hooked everything up while the tank was on the ground and raised it up, the only bitch thing was the filler neck

Re: Gas tank removal?

Don't waste your money on those books for this simple stuff.
Pull your bed, way easier to get to the tank to see the real issue. You might can even fix it as well. Depending on if all it needs is the rubber o ring around the sending unit.
