Curious M49 fuel tanker

Hello everybody!

Let me give the new forums a go!

I’d like to start a new topic with a photo that has already been posted previously:
real_thing.jpg

Funny thing about it is that at the same time it is inscribed “Flammable” and “Potable water”. The best explanation I came across for this is that a fuel truck has been pressed to transport water (in war that happens) but they didn’t get rid of the “Flammable” inscriptions because they expected to get back to hauling fuel some day. I sure wouldn’t want to drink that water…
At the same time we have here a “gasser” version of the “deuce and a half”.

The base for my build is the AFV Club kit:

176525-15772-15-pristine.jpg

The kit shows the later version of the fuel tanker, so there will be some converting…

I started with the chassis:

chassis01.jpg

I replaced the grabhandles on the frame to match the photos of a “gasser” that I got from a collector owning a similar truck.

When assembling the axles it’s good to put the whole thing on an even surface, to prevent some of the wheels from hanging in the air later:

chassis03.jpg

As you can see I have scratchbuilt a new frame crossmember under the cab (the mounting of the transfer case will be a little different). I’m also building a different front engine mount crossmember for the gas engine.

The engine itself is simplified in the kit and I think I’ll stick with this solution, but I’ll have to rework it a little, to show the gas engine. Now it looks like this:

chassis04.jpg

I filled the ejector pin marks and I closed up the hole in the fender for the exhaust stack. From what I see I’ll have to make a new oil pan and maybe this will be enough.

So that’s it for now - thanks for looking and have a nice day

Looks like a fun build, looking forward to the updates as you go along. Nice job on the scratch built crossmember.

I want one of those in 1/48!

The AFV kit was more often called a TPU or Tank & Pump Unit. Together with the M35 series truck, the end result is the M49 fuel truck.

The notion of non-purpose built fuel trucks is that if the truck itself is down, theoretically, you can put the TPU into the bed of another truck and continue to provide fuel.

Being in armor units, our fuel trucks were HEMTTs and 5 ton TPUs.

Hello everybody!
My best wishes for you in the new year!
Thanks a lot for your comments and for your kind words!
@jeaton01 - looks like the 3D print is your only option here if you insist on 1:48!
@Rob_Gronovius - yeah, that makes sense. Still they had a number of dedicated fuel trucks back then in Vietnam.

And I have a small update here:

chassis05.jpg

I have installed the air tanks to match the photos I have, the transfer case is also installed as are the propeller shafts and the rear crossmember. The front crossmember is ready to be installed as soon as I figure out the details of the front of the gas engine.

Thanks for looking and have a nice day!

Really nice work Pawel! I’ll be looking forward to seeing how this turns out!

Cheers,

It occurs to me that they are taking advantage of the separate compartments in the main tank to carry water in one and fuel in another. Not recommending that…

After seeing this chassis build up it looks like this kit has a fair amount of details in it. Looking forward to seeing more on this bad boy TB. :+1:

Hello everybody!

Thanks a lot for your comments!

@Striker8241 - good to see you on the forums again, Russ!

@jeaton01 - in that case the products would constantly contaminate each other, wouldn’t they? I already previously wrote the explanation I like best - that this is a fuel truck pushed to work as a water truck, but they didn’t paint over the “Flammable” signs, because they thought it might be used a s a fuel truck again…

@mustang1989 - it’s a nice kit although it’s showing it’s age a little. Let’s not forget it was one of the very first kits of AFV Club and they were just learning how to design plastic kits back then. After 30 years still the best styrene kit of the Deuce…

I didn’t write recently, because building this model went over to 3D:

But soon I hope to be done here and then I’ll just wait for the prints…

Thanks for looking and have a nice day

Pawel, the tanks are separate compartments so different fuels or oils can be carried on the same trip. They should not mix unless the drain valves are operated incorrectly. Water trucks are not made that way but they have bulkheads every so often with openings at the bottom of each, that is to prevent sloshing which can upset the truck. Tankers require special endorsement on most commercial driver’s licenses if not all.

Hello John!

Thanks for explaining! I still don’t think they simultaneously carried water and fuel - but I don’t have a way of knowing for sure.

I have another update: The real fun begins now - I got my 3D printed parts from the printer today. Here’s how they look like:

The thread-plate looks a little coarse in 3D and in close up, but in person it’s just fine. There’s a whole jungle of supports there - removing them is a bit like solving a puzzle, that can be fun, too! I hope to post some assembly photos soon!

Thanks for looking and have a nice day!

Now how cool is this? Looking forward to the “real fun” @Pawel .

This whole 3D printing business has opened up many…many doors to us here in scale modeling.

@mustang1989 - thanks a lot for your comment and for your kind words!

Yeah, 3D design and 3D printing is a major game changer in this hobby!

And here’s some “real fun” for ya:

I put the wings on the frame:

chassis06.jpg

I printed them with the supports that help to keep them straight. After the glue (CA) sets, they will be cut off at the red lines.

Then I dry fitted the parts:

chassis07.jpg

Looks like everything fits, yay!

In this case I can start putting everything together:

chassis08.jpg

The photo above also has the 3D printed steering gear and the front exhaust pipe made of 2mm soldering wire and also muffler made of leftover sprue and plastic sheet.

I’ll try to fit more parts now - thanks for looking and have a nice day

Hello!

Took a little longer than I thought, but I’ve got another update - I was working on the chassis and also on the cab:

chassis09.jpg

chassis10.jpg

chassis11.jpg

As you can see I’ve replaced the bumperettes with sheet metal to hopefully make them look better.

Similarily I’ve had an accident with the step boxes and I repaired them with other sheet metal:

boxes01.jpg

I also started working on the tank. First I had to cut off the later sides:

tank01.jpg

Then I had to do some fixes and tweaks:

tank02.jpg

I’ll soon have everything ready for the 3D printed older sides.

I was also working on custom decals and now I’m waiting for them to print.

That’d be it for now - thanks for looking and have a nice day

Hello everybody!

A small update - at last I got my 3D prints:

tank03.jpg

After dry fitting them:

tank04.jpg

I’ll try to add the control cables for the valves, although it’s going to be tricky, as not everything fits right.

I was also working on the cab:

cab01.jpg

The lights on the wings are old stock (Shapeways - my design!):

cab02.jpg

And I made the dashboard:

Thanks for looking and have a nice day!

Looking great. The prints are awesome.

Was finally able to get back on this forum. Looks and functions just like Armorama now.

Welcome back, HeavyArty! Yes, Pawel’s doing a great job on the tanker.

Hello everybody!

@HeavyArty , @GAF - thanks a lot for your comments and for your kind words! Gino - good so see you here, too!

I made a breakthrough on the tank. First I patched the front bulkhead:

tank05.jpg

Here is my rendering of the control cables - I was not sure about fastening the cable guides, so I just made them “float”:

tank06.jpg

This shot shows off the 3D printed parts and plugged holes for the hose hooks:

tank07.jpg

Other side:

tank08.jpg

I still have to fill and sand the joints. I also plan to restore all the small details, like the hose compartment doors, tarp hooks and so on.

And here’s one more dry fit shot:

Thanks for looking and have a nice day!

Very nice. Great job.

That is the correct assumption. These tankers had like 3 or 4 compartments. Could carry both, plus that setup reduces surges of the liquid. The picture is obviously of a tanker in Vietnam. I’d know that red clay anywhere. Had to deal with it for a year’s tour. 1965-1966 Pleiku, Pleiku Province, SVN.
