New Gas Tanks ? 1941-'48 Mopar ?

[Plymouthy Adams]

Shel..when I first clicked on the link the only thing that was returned was a huge file with the photo of a 15 gallon trunk mounted fuel cell...thus spurring my comments....I click again to the link above on reading your note back to this thread and the page linked to a e-bay page where if you scrolled you would find the Jeep reference tank...very confusing morning it seems...

 

my thoughts on the fuel cell use remain unchanged however...lol

OK.  yup, fuel cell would be a temp sort of a thing. Sort of like the Plym coupe that I went to look at, and they had a "pony keg" in the trunk as a gas tank.

Wayne,

 

Thanks fo the link;  let us know how it looks and fits...

 

 

Thanks !

47heaven, and fargo55 have installed these tanks. You might search their threads for the things that they did for installation. Seems there may have been 1, or 2 others that used the Tanks Inc tank.

You need to be wary of fuel cells; a lot of the sports racers that I used to work on were seeing delamination of the bladder because of the requirement to use pump gas.  New bladders and switching to race gas was the fix!

I should add that this problem occurred after a couple of years of mostly weekend use.

There are 15 gallon, 25 x 18 x 10-7/8 fuel tanks on ebay for around $80.00 delivered.

 

They are for the older Jeeps.

Maybe I did not post the link correct.

 

Here is a photo of the fuel tank I was trying to refer to.

Andy Bernbaum has tanks and mounting hardware for $275. No clue on how original they are. http://www.oldmoparts.com/parts-fuel.aspx

Most likely a Tanks Inc resale , but only speculation on my part. I'm sure Chris would give details of the style if anyone is interested.

Well, the Plymouth is back on the road! Here's an update with some pictures in the event someone is considering a Tanks, Inc. replacement tank. First of all, the tank is well made, and heavier than the original...however, there are a few things to be aware of.

1. As noted previously, the tank is a different design than the original. It's going to work out OK

in my P15, but would also look right at home on a hay baler. It's just a rectangular tank.

2. A molded gas filler hose was provided, but my original gas filler tube would only insert about

1/2" into the new hose. To fix that, I got a short length of steel tubing, and extended to fit.

3. I used the new straps that came with the tank, but used the "hooks" from the old straps. They

were fairly easy to fabricate, and I could still use the original barrel nuts in the trunk floor.

4. I installed my aftermarket gas sender unit, but I think there may be interference with one of

the internal baffles, because it won't read above about 3/8 of a tank on the Sunpro gauge. And

the mounting flange holes are not symmetrical, so I can't turn it to reposition.

5. There isn't a strainer for the fuel pick-up...it's just a 3/8" diameter tube that is positioned

about 1/2" above the bottom of the tank.

6. In my case, I installed an Edelbrock electric fuel pump near the tank, to replace the Mr. Gasket

(junk)fuel pump that failed after about 2000 miles.

7. I hope this information is helpful to anyone considering one of these replacement tanks.

5. All in all, the tank will work out fine, but it is definitely not quite as easy as I expected.

Shel,

 

All in all, it looks pretty darned good... if you painted the tank black,  I would bet that only a Flathead MoPar expert would know that it's not stock...

Thanks for sharing your experience...

 

Let us know how you resolve the sender connundrum...

Autocityclassic.com has a 17 gallon tank listed for '41-'48 mopars. The price is $194.00 + shipping. Has anyone had experience with these tanks? I have been looking at the tanks inc 15 gal but this one is bigger and slightly less money. The pics look pretty good but the website disclaimer says actual tank may vary from photo. That makes me a little apprehensive to just order one and hope it works. Any input would be appreciated.

Autocityclassic.com's tank looks almost identical to the Tanks,Inc. offering, right down to the molded filler hose. But it seems odd that they claim the picture may not actually represent the tank being sold. Kinda like buying a "Pig in a Poke". Their tank might be just fine and dandy, but I think I would want to see an actual photograph of what I am considering buying, before making the purchase. And I would want to actually talk to a representative to get any questions resolved prior to making the purchase.

(And even though I did that with "Tanks,Inc.", I was a bit disappointed with the fill tube issue that I encountered.)

Your tank install looks great!  Unless someone knew what the original tank looked like they would probably think that the new tank is stock.   I can't believe how clean the bottom of your car is.  Mine was originally a Massachusetts car, and by comparison it looks like it spent 50 yrs on the bottom of the ocean.

 just had my 39 Desoto into the shop for some other repairs and we discovered that I had a leak also in my original tank.  I called around and Mitchell wanted 900 for a NOS tank.  The mechanic sent the tank out to a gas tank specialist to get it repaired.  He informed me that if the guy can not repair the leak then they ( expereicned gas tank guy) would then install a bladder inthe tank.  This would be the type of bladder that they have inthe NASCAR gas tanks.

 

The tank should be done this week so I do not know much more on this but will let everyone know how it comes out and the cost.  I am trying to keep the original tank and not have to convert to an aftermarket and then go through alot of customizations to get the tank to work.  I have a driver so want to keep as much originality as possible.

 

Had the car over 25 years and this is the first major issue that I have had and the tank was original to the car.

(snip)

This may not be as good an idea as you think.  Most fuel cell bladders have problems with delamination because of the ethanol in pump gas.  Be sure to ask about that before he puts one in!

[Plymouthy Adams]

cross that bridge later..give the tank repair guy a chance to work some magic on the original and fix the hole..would not think it catastrophic if you were driving it unnoticed all this time..

[desoto1939]

I have been told that when they install a bladder the tank need to be heat so that the bladder then seals itself to the metal tank.

The cement or sticky material would then have to unbind itself for a bladder to delaminate.  The enthinol should not cause the bbladder to delaminate. For this to happen the enthinol would have to go throught the bladder then loosen the cement.

 

This is an old time repair guy and we will see how it goes and I will get back to you after getting more info.  Hey also the NASCAr cars use bladders. Did some reading and methanol seems to be the bigger issue and not ethinol gas.  Some even state to use dry gas inthe tank but I will wait for more instructions from the tank guy.

Rich,

 

All of the bladders I have seen have a glued seam somewhere, and that is what comes apart.  NASCAR isn't a good example, as they tend to throw the cars away and build new ones every year.  I was speaking from personal experience in the SCCA arena, where a number of classes require pump gas in a fuel cell.  They all tend to have problems in the 2-3 year timeframe and wind up replacing them.  The classes that allow racing gas don't have this problem.

bringing this  topic back to  life,,,,  my  tank 1940  dodge is original,,ide be willing to bet  the drain  plug has never been out,,,my tank does not leak it was a southern car,,,but the issue  im having is this,,,the car has been parked for 6 ish  years,,,now back on the road,,,during the time it was off the road,,,  i kept fresh gas in it and  started  it  once in a while,,

 

i recently got it back up and running,,,and  had  problems keeping the plug clean,,,lots of gas on them,,,,had a simalar problem on a super charged car,,,,I just happened to read an  artice in  street rodder  on todays GAS,,  in a car that doesnt get  driven  every day,,and  still has a steel tank,,,,they were dead on,,,,my carb  looked  inside the same as the one they  pictured in the magazine,,but not as bad,,,,newer carb  low miles,,,lots of  rusty  powder  in the carb and  eating the carb  bowl,  took it apart completely,,carb  cleaner,tooth  brush and  compressed air,,,  car purrs like a kittten  now,,,

 

so a tank is my next project,,,  I read that the  tanks inc steel tanks have an  aluminum  coating to prevent the  rust from the  gas of today,,,,SO MY  QUESTION IS,does  any one makes a poly tank that  is able to  use the  side fill  like the  original tank,,and  not  in a race car fuel cell style  of  gas cap on top of tank,,??     thanks for posting  pics of the tanks inc install,,,,

[OldDad67]

I need to find another gas-tank for my '41 De Soto...

 

It is a 17 gallon tank.

I am assuming that most tanks from 1941-'48 MoPar car will work.

 

Is anyone making re-pops, or am I at the mercy of Gas-tank Renu ?

 

 

 

 

Thanks,

 

Frank

 

I used a tri-5 Chevy tank so I could run dual exhaust without tank interference. It worked well and is 16 gallon. I cut a hole in the top of the tank for the Plymouth sender and used the Chevy sender pick-up tube for fuel pick-up. I had a piece of exhaust tubing cut and one end expanded from 2" to 21/4 for the stock fuel inlet hose. The system fit and adapted well. Tank price new was $75.00 off evilbay. Just another way to replace your tank.

[BobT-47P15]

Good pics Frank.   If that tank is more narrow than the original.......is it taller (or thicker).......than original?  

 

If taller......how much?     Does it hang down below the car farther?        I am at the point where I need to

eventually get a new tank.........have looked at some new items sold thru O'Reilly Auto Supply (there is a catalog)....

and the closest match seemed to be something for a Jeep or older Mustang.   Those would still need certain mods.

You might want to give Berbaughms a call. I called and they had the after market tanks as well as a couple original tanks for my P-15. The after markets were $250 and the originals were $275 I think. Any how I ordered an original and it was in pretty good shape when I got it. Had a little rust in it, but I took a length of chain and put it in the tank and swished the tank around for a while then flushed it with some old gas. No more rust spots in the tank.

 

Also to note that the fuel senders for the after market and the original tanks are not interchangeable.

nice  job on the tri 5  transplant,,,,the question is,,,new or old  tank,,,how long till todays gas  makes rust in a new tank ??

 

the tank you showed on  e bay  is from  tanks inc,  it is  aluminum  coated steel,,,may stand a chance  of surviving todays gas,,,

 

tanks inc has a poly tank for  1936/37/38  plymouths wit ha side fill,,,but says  the mearsurements are way  wider then the  41 to 48  steel tank,,,im going to  do some measureing see if it will fit  my  40...

 

only thing that bugs me is there side fill,,,it bolts on with a flange,,how can  it  not leak ??
