JB weld vs. Fuel

[Tony724]

I poured 5 gallon of fuel into my tank on my 1952 Plymouth Cambridge, and it started leaking out of the male end where the fuel line screws into. I looked online, I can only find a new one on ebay.

However, trying to save some money just for now. I put JB weld around the male lug that is fixed to the tank. I did wire wheel the area, and it was shiny and clean. Will JB weld hold up at all against fuel?

Here's a photo of the leaky area.

 

Here's a link to the tank if I need one. I can't find one anywhere else.

I hate ebay because I have gotten parts that don't fit, and its a pain to ship back. It does say fits 1952 Cambridge. I dunno..

I think the JB Weld will do the trick !  I do see some so rust in the female area. Hope that isn't an indication of the rest of the tank.

[Young Ed]

If it doesn't that tank sure looks right and with the sender thats one heck of a price

Yes, there was a slight rust to that area, as soon as I posted the photo I seen it too.

When I shined my light into the tank, it is all clean inside, for except the sending unit has some crust on the end that floats. I don't get it.

Just the neck where the hose hooks onto for the filler tube inside. I can clean those things. I hope the JB weld will hold long term, will help me use momey elsewhere.

Yes, it does look the same. I kept debating on ordering a new one. He has good feedback.

I sealed a few pin holes in my gas tank with JB Weld.   It's held up fine

[Mark D]

JB Weld kept my tank from leaking for the past four years.d

Awesome! I am trying to save some money on this part if possible.

Okay, four years is good! If I can get one year out of it, just until I get other stuff done on it. It was leaking right about that square lug that the line threads onto. It was a very minor leak, but enough to cause an issue with it dripping on the ground. I must admit. These cars don't seem bad to work on. The tank came out very easily.

One note...

The 1949-52 fuel line tube nut and tube that fits into the tank is special... a bubble flare tube formed end and copper washer...all needed so the line does not leak at the square tank fitting.

For anyone with a leaky gas tank, and if you are in an area where you have a heated garage, I would not use JB Weld. I love the product but when it comes to leaky gas tanks and an open flame, I would take the tank to a local radiator shop and have it soldered properly. Leaking gas and an open flame, like a pilot light, is asking for trouble. I have a heated garage and always check my tanks, fuel lines, and filters on my cars before lighting the furnace. Just my two cents worth. Guess it has to be a nickle's worth as we no longer use the cent in Canada.

Many years ago I spoke to an old guy that got a rude awakening at 3 in the morning . He was woke up by an explosion . The double door of his garage blew off and hit a home across  the street  .   His garage walls were bowed outwards . windows were broken , etc . I asked him what might have caused the explosion and he said " It must have been the gas leak on the truck . "

Mine was leaking out of the square lug on the tank for sure.

My flare is on the end and looks the same as yours.

However, I will check right now and return with pics. I don't believe mine has a copper washer on the end.

I would has noticed that. Unless it is buried into the female part of the lug that it threads into? Thats a wonder mine wasn't leaking there, if the copper washer is missing.

I use a Torpedo heater in the winter. Thats why I want this repaired. I don't want an incident.

Oh great! Now you got me afraid! I went into the garage just a bit ago, for a screw driver, and it is strong in there. Of course, I have the gas tank laying there with gas in the bottom of it while the JB wled dries.

[Tony724]

Ah ow! Okay, luckily mine wasn't leaking at the fitting.

But...I just took photos. I don't see a copper washer? Is there anywhere I can buy a washer specifically for that? Or a new fitting and end with the washer?

Here's some photos.

Heres the inside of the tank, the best shot I could get.

[Jerry Roberts]

Can you put the gas tank outside ? Perhaps under a tarp to keep it dry .

Since you don't use the cent anymore, maybe the government can send them the to all the radiator shops to repair leaking gas tanks. I've seen pennies soldered to gas tanks to fix holes in them.

Hey Tony,

 

You should be able to buy your copper washer at any hardware store. They usually have a good selection of sizes in stock.

 

For anyone else who may have a small fuel leak on the tank, JB Weld works pretty good. That being said the best tool in your repair kit for on the road, is a small bar of ivory soap. It has to be a bar of soap not the liquid kind. Gas will not eat through soap, and you can use it to make an emergency repair to your tank until you can pull it to make a permanent one. Here is how I know.

 

My dad told me.

 

Really he did.

 

I was about 14 years old at the time and we had a family station wagon. Must have slung a small stone or something and it put a pinhole in the tank. My dad used the bar of soap and rubbed it across the hole, caking it in and it stopped the leak. Sold the car a few years later with the soap repair still in place.

 

7 years later. I'm rolling down U.S. highway 64 at about 3 am. Had a blow-out on my left rear tire. The truck I was diving had two 20 gallon saddle tanks just forward or the rear wheels. The tanks were plastic, but that didn't matter. The tire tread smacked the corner of the tank cracking it. The 3 cracks radiating out from the impact area about 2-3 inches. I had gas leaking out onto the remains of the tire. My spare was shot and I'm 1 1/2 hours from home. I pulled out my shaving kit got my bar of soap out and smeared it into the cracks on the tank. It stopped the leak dead in it's tracks. Limped to a station a few miles up the road and spent the rest of the night there until it opened and I could get a new tire.

 

That soap repair lasted over 5 years. The only drawback to this repair is if you live in a wet area. The water will eventually wash the soap away.

Well, I have to change the tank for sure. After draining the fuel out, the one side of the tank is covered in rust really bad. I am going to order the one on ebay.

This one...says "Make Offer"...I may try to ask if he will take $250.00 and see what he says.

Hope it fits properly...

At least is comes with the float. My filler tube has rust in it also.

Any ideas on how to get the rust out of that long filler tube?

While it is out, I am cleaning that whole area under the car. It does look clean, but I want to redo it, while the tanks out of the way. Freshen it up.

An old choke or throttle cable makes a good auger to put in your drill for cleaning out a tube . Perhaps your new tank will have the common fitting that would take a new inexpensive brake line and fitting . 

[Smokeywolf]

Leaking fuel tanks don't mess with them just replace along with the fuel lines.

I new a couple of brothers who welded a tank at work

One was killed the other had a lot of plastic surgery.

It was a hard lesson for the whole family.

I offered $250 for this tank 2 weeks ago and was rejected. Let me know if he accepts and I'll offer again.

[casper50]

see above. new tank $250

Hey, thats a good idea. I have thick mechanics wire. I can use that, thank you!

Thats very sad honestly. I just want a new one, and all new line all the way to the front. I may have to find fuel pump gaskets. Even for the pump itself, I would like to take apart, and clean it out. If they sale that type of kit.

Thank you. I like the second one. The new one. I punched in 1952 Cambridge, and it says it won't fit. I don't get that??? Is that an error. Because I think it said it fits 1952 Cranbrook. Aren't they the same?

[JerseyHarold]

Cambridge and Cranbrook take the same tank.  The listing on eBay for the new gas tank has some errors.  It incorrectly shows that the tank fits a '52 Savoy, which is a wagon that has a different tank.

[Plymouthy Adams]

the two links does not show a wagon fuel tank..having removed and replaced mine and documenting the process with photos..I can say this..if I were not so feeling lazy I would go upstairs and photograph an actual 51/52 fuel tank..but having moved my tank 5 inches to the right to center for ease of running dual exhausts in the club coupe..I can say the tank pictured will fit my car with no problems
