The idots back with another gas tank question
**Disclaimer - This is my first car project ever..and this is my first project on this car.

First question - As Im tinkering with various hoses, I see that a lot of the clamps are metal bands that are crimped at the top. Kind of forming a triangle or trapezoid shape. Simple question, Is there a tool for removing these?

second question - 83 CJ7 been sitting for a decade - made a huge mistake of ordering my gas tank before I actually dropped it. turns out I dont have a factory 15 gallon tank, i have a factory 20 gallon poly. I cant seem to find a straight up replacement for it. Anyone have any suggestions. I found one on eBay, but Id like to get something new from a buyer I can trust.

For the first question I have just taken a screwdriver to it until its loose and then replace it with the usual band clamp ones.

Second I don't own a 20 gallon tank but I believe both quadratec and 4wd have replacement tanks, I think MTS has one too.

Thanks James - so after some quick research, i guess this is some kind of a Oetiker clamp. There has got to be some kind of remove tool.

Ill look up the tanks you suggest, are these websites?

james04si 07-13-2013 12:30 PM

Yes all have websites. MTS you actually have to call to order them but the guys there are top notch and I know make the hoses in house. I have heard they are even the suppliers to others. I'm sure there has to be an easier way with those clamps too but its not too bad with a screwdriver either. I have even used a pair of dikes to cut them off, its not like you plan to reuse them anyways.

Looks like Quadratech carries the MTS tank which is the same one at morris 4x4. The problem is that it says right in the description "replaces 15 gallon tank only, will not replace 20 gallon oem". Im assuming has the same. Is there really no straight replacement. seems odd to me.

Yuma84CJ7 07-13-2013 01:27 PM

There is no direct replacement plastic 20 gallon tank, mine cracked and i had to find a used one on ebay also.

texas1al 07-13-2013 01:38 PM

Yeah, there's no replacement for the factory 20 gallon tank or skid. Used one's are expensive for this reason. I suggest paying up for a used one if your current tank is not repairable or finding some info on getting a replacement one to fit. What's wrong with your current tank? I think switchig to a 15 gallon tank is doable and new parts are more plentiful, but it's a pain because the sender is different and the rollover check valves are up in the drivers rear fenderwell (and hard to find). Would probably cost as much as getting an expensive used 20 gallon that just drops in. For the clamps you mentioned, you can usually get the points of a tin snip in the crimp to cut them off.

Thanks for the replies guys!! Again, Im new to this, but Im shocked. With the number of sites and random parts out there for CJ's, no one makes a replacement for the OEM 20 gallon? Crap. Mine must of cracked from just sitting in the sun for a decade with fuel in the tank. I dont really want to downgrade to a 15 gallon. If anyone knows of any threads on any forum where guys have replaced a 20 with a 20 or 21...please let me know!!.

texasdave 07-13-2013 02:09 PM

I did! The only thing I had to do was use the extension plates that came with the MTS tank. It was very close to the original size. I used the original skid plate for the tank as well. You can order direct from MTS and their tanks come compete with a new fuel sending unit.

VPALLARI 07-13-2013 02:33 PM

Thanks Dave. so you you replaced an oem 20 gallon poly with the MTS 21 gallon with the extensions? So you just dropped it in the original skid plate, added the extensions and all the holes lined up?

Im also considering this:
They make a 26 gallon steal with skid plate, but looks pretty pricey

VPALLARI 07-13-2013 02:35 PM

Hey Dave - is this the one you used??

VPALLARI 07-13-2013 08:31 PM

so i have 3 more quick questions as Im planning on getting this MTS 20(21?) gallon tank ( )

1) It looks like forward most holes on the skid plat extensions should line up, but the back end extension only has 4 skid plate has 5. On the factory OEM 20 gallon set up, there are 3 holes to the driver side. Anyone who has done this, how is this rectified
2) Attachments. I get the input hose and the vent hose, pretty straight forward. The sending unit has 2 inputs, same as the old tank. My old tank (link in post number 1) has 2 inputs?? on top of the tank. How do these map to the MTS tank. I guess a simple way to put it, can someone diagram the those hoses for this conversion. 20gallon OEM to MTS 21 gallon tank?
3) My old tank as 2 electrical components on the sending unit. One that attaches to a threaded bolt and one that attached to a flat piece of metal. The MTS tank has the same bolt, but off the flat piece it has a 12 inch piece of wire with a flat round screw connector...line a grounding wire. Should I just take the wire off and put the plug it into the existing wire(s) like my old tank?

texasdave 07-13-2013 10:07 PM

Go here: part number 051XL. Look at the instruction sheet for installation it is pretty straight forward. I have a rear frame from a 1986 CJ-7. (don't ask how I ended up with the rear half of a 86 frame other to say rust and Obama's clunker program) everything lined up just fine.

VPALLARI 07-13-2013 11:40 PM

Thanks again Dave. Thats the tank Im looking at, but the same questions still apply
1) 4 attachment points in the rear, mine has 5
2) the 2 additional inputs (im guessing they are the return inputs?
3) electrical components on the sending unit

Not trying to be a pain in the ***, but this really is my the first project of my first venture into rebuilding a jeep. I already made the mistake of buying the wrong tank, sending unit and hoses. Id just like to get through this part before halloween.

The skidplate for the factory 20 gallon is different than the 15 gallon. The two "inputs" are actually rollover check valves. The 15 gallon check valves were located up in the fender wells. Personally, I would try and scare up another factory tank to replace what is there. They are out there. But, since you already have the wrong parts, you may as well pick up a new skidplate and be done with it.
