bambamshere Posted May 10, 2017 Report Posted May 10, 2017 Hello I was wondering if anyone has any ideas of how to get a rusty sending unit out. Its probably been in the for 60 years or so. There's no screws on it. Juat need to turn. I have been beating on it for couple hours now. Yes I am trying to turn it the right way. I have sprayed it with PB blaster. But not sure if that will even help. Quote
knuckleharley Posted May 10, 2017 Report Posted May 10, 2017 (edited) Try building a "wall" around it using body plastic or anything else that might work. Once you get the "Walls" up,pour the center part that where the sending unit is full of vinegar. Vinegar eats rust like nobody's business. Let it sit over night,soak up the vinegar,and try to loosen it again. If you get it to move even a tiny bit,spray PB Blaster or something similar around where it spins and use a chisel to tap it open and closed and until you can get it to spin,spraying the PB again with every move. Repeat as necessary until it comes free. BTW,if the top of the tank is really so rusty your sending unit is rusted in place,chances are it is so full of rust on the inside that you are wasting your time fooling with it. Yeah,you can half-fill it with vinegar to eat the rust,let it set for 24 hours,pour the vinegar into a tub,turn the tank over after sealing the top,and let the vinegar eat that rust too,but the sad,sad truth is it is going to start rusting again immediately. There are coatings you pour in your now clean tank that are supposed to coat it to keep it from rusting again,but I am not so sure they work with ethanol. AND.....,it's a lot of damn work to do all that and then have to drop your tank and clean it out again after the fuel line and filter gets clogged up again with gas tank sealer. I went through that crap maybe 15 years ago,and now I just go ahead and buy a new tank from Tanks,Inc or a similar supplier,and spend my time doing other stuff. One of the things I hate most of all is coming home on a rollback. Buy the time you do this twice,you could have bought a new tank. Edited May 10, 2017 by knuckleharley Quote
Plymouthy Adams Posted May 10, 2017 Report Posted May 10, 2017 perhaps a picture of the mount so one can see what method of lock you have on the tank... 1 Quote
bambamshere Posted May 11, 2017 Author Report Posted May 11, 2017 I soaked it over night with PB blaster and then used a 8 pound sludge hammer and a screw driver and it started turning. Just taking old tank out now and will probably have to do same thing. 60 year old rusty piece of stuff lol I really think this is fun am I wrong lol Quote

bambamshere Posted May 11, 2017 Author Report Posted May 11, 2017 Does anyone no on a 1956 dodge fargo truck. The springs on the gas tank bolts go on the front or back of the tank. They were on the front but the back is the part that bolts to bottom of frame. Quote

You are probably better off posting truck questions on the truck side of the forum. I have only ever seen gas tank springs mounted on the back of the tank. I have a 56 truck in my shed. Our Oz trucks are slightly different to yours over there, but the gas tank springs are still mounted to the rear - on an angled plate which mounts to the chassis cross member. We had a chat recently about gas tank mounting. There is also some good information on the truck side of you use the search function to the top right of your forum screen. I always have a laugh when someone calls these trucks a Dodge Fargo - it will be either one or the other. Quote

bambamshere Posted May 12, 2017 Author Report Posted May 12, 2017 Thanks for that I will look and start posting on the truck side Quote

While there are differences, a lot of of information is applicable to both cars and trucks and this topic seems like it may fall into that category. 2 Quote
Dennis46PU Posted May 12, 2017 Report Posted May 12, 2017 I don't know about the 56's and once worked on a 54 about 50 years ago but can't remember. On my 46 I put the springs on the rear because if they were on the front where the gas line connects, it might loosen the fitting on the front of the tank when it would twist with the springs. Just my opinion... Quote
bambamshere Posted May 23, 2017 Author Report Posted May 23, 2017 So I finally got gas tank in the truck. I was installing on ground, on my back, with one leg holding it. Probably good for a funny photo picture. I put the springs on the front. I will see how it works. If I have to move to the back I will. I did notice something how ever. When I took the old gas tank out of my truck the seem in the corner at the back was split. I wonder if it was because to much flex at back of tank and thats why maybe springs need to go in the back. Not sure I'm going to have to find and buy a shop manual for this truck. Quote
Desotodav Posted May 23, 2017 Report Posted May 23, 2017 The attached picture from the manual should help... 1 Quote

bambamshere Posted May 24, 2017 Author Report Posted May 24, 2017 I wish I could find a manual for a 56 Fargo. I have been looking but can't seem to find one. Anyone know where you can find one. Quote
bambamshere Posted May 24, 2017 Author Report Posted May 24, 2017 So I guess the springs are supposed to go on the back of the tank. Quote
