When I pulled my tank down, took the pickup and sending unit out to check the inside condition of the tank. It had a bunch of scaling rust and the filter on the end of the pickup was caked in varnish and the screen was in bad shape. Took the tank to a radiator shop and they cleaned it to a shiny surface. Repainted the tank with Duplicolor Gloss Black Epoxy paint. I bought the filter + other stuff, from Griffin Motors. The fuel lines were cleaned with carb cleaner and blown out. Good luck, a pita but necessary to get us guys back on the road

 

Is the hole in it big enough to get our hands in and sand out?
We were wondering about that and then repainting the inside with some rust/gas resistant paint? You guys paint the inside? Sort of 'seal' it back?

 

No, both holes are same size, around 3" diameter. Some have put rocks into the tank and shake around to remove the rust, if you have the time. You can YouTube search for cleaning fuel tanks. Once the tank is clean, then buy some tank sealer to slosh around and let cure.

Just a note, when you the gas hoses off pickup, mark them front to back so you won't get them mixed up when reinstalling

 

I'm thinking take to the radiator shop. LOL.

 

If you dont mind waiting a few days, I fill my tanks with white vinegar and let them soak a few days and once a day or so I slosh it around occasionally while it is soaking. Then spray it out with high pressure water and let it dry out. When it is good and dry, I buy a can of Red Kote that I get at Oriellys and coat the inside of the tank. On all of my build below, I have done this on each of my builds and it works great. The 88 runner build has more info on the first post if you want to look into some other ways of cleaning it.

Here is the filter part number and where it is located in the tank on carbed models. Most dont know about it or how bad it can get.
Part Number is 77023-12050.

 

I would second the thought of taking it to a radiator shop...my tank was HORRIBLE and after a trip to the local radiator shop it literally looked brand spanking new...I had tried nuts/bolts/gravel and degreaser without any real success...I wish I would have gone there at the beginning...literally just took him a few hours and I was amazed by the results. The after pic is in my build thread.
