G506 Fuel Tank Lesson
Gentlemen,
I recently acquired an old fuel tank that I initially thought was for a panel truck. As it turns out, Tony sent me an image of the tank from his panel and this new tank is certainly not from a panel. As this peeked my interest, I started measuring and thought I would share some items found. The part manual states 3 different fuel tanks for all models.
Tank 1) This tank fits all cargo body versions (39 inches)
Tank 1) Filler neck of tank above, notice that the neck is angled toward the front
Tank 2) This tank fits all dumpers, COE, and tractors; note that fuel filler port is perpendicular to the truck frame
Tank 2) Same tank as above showing length (39 inches)
Tank 3) Here is the "new" tank origin/application unknown, notice different length (43 inches)
Tank 3) Same tank as above, notice the filler neck is located more to the rear than the other tanks. The cast filler neck appears to be identical to the other tanks.
So here is the question...what application is the last tank supposed to be used for, and why is the filler neck moved rearward? Is it from a auger, pole setter, or fire truck? I hope some of you folks can help me solve this little mystery.

Re: G506 Fuel Tank Lesson
I have no idea, but ...
I remember the difference between the Budd cargo bodies for the Chev and the Dodge VF was the fuel tank filler position. How sure are you that it is Chev and not GMC or Dodge?

Re: G506 Fuel Tank Lesson
I can say with great with great confidence that this is not the fuel tank for the Auger or Telephone Maintenance truck.

Re: G506 Fuel Tank Lesson
Some of the CCKW Van Body variations take a similar flat tank. I do not have the specs on those tanks.

Here are a couple of pics of my panel's tank, for what it's worth.

Re: G506 Fuel Tank Lesson
Tony, thanks for adding your tank to the photo collection...I was hoping you would as I didn't want to submit the image you has sent me without your permission.
Any images of a auger or pole setter fuel tank?
Joel, I never thought of the CCKW van body models. I was only considering the passenger side and spare tire mount fuel tanks on cargo and dump bodies.
As for the question if this tank was from either a GMC, Chevy, or Dodge; I don't know definitively but I did happen to recover a part number from the cast filler neck.
The part number is 3661091. Numbers containing the beginning numerals of "366" are common to WW2 production Chevrolet's so I feel relatively certain this tank was originally fitted on a Chevy.
Does anyone have any images of a fuel tank from the firetruck models?

Re: G506 Fuel Tank Lesson
The part 3661091 is not listed in the numerical parts index of the SNL G506 Ord 9 parts manual for the G506/G085 family of trucks. There are some numbers VERY close, and they are listed in section 3.06 which is the fuel tank section...

Re: G506 Fuel Tank Lesson
That part number will be unique to the filler neck I expect, so you need the next part number level up, sort of thing.
US practice would be to serialise all the components first, and then the main assembly, so anything 3661091 - up but within about ten numbers I'd expect.

Re: G506 Fuel Tank Lesson
Hi Paul and all,
my 1942 dump has a lower filler neck, by that I mean the straight section of the vertical shaft is a good 1 to 1.5 inches lower than the tank necks shown. I have a spare unrestored tank, and this is exactly the same. I have always understood this was a typical thing for dump trucks, but I dont have any conclusive proof to back that up. I cant get to the tank currently as I am away with work, but I will have a look to see if I have a photo with me somewhere

Re: G506 Fuel Tank Lesson
While I agree that would seem to make sense, the parts in question are actually listed as "Neck", and are different parts then the fuel tanks themselves. They apparently were considered a replaceable item.Gordon_M wrote:That part number will be unique to the filler neck I expect, so you need the next part number level up, sort of thing.

Re: G506 Fuel Tank Lesson
My take is that elbow is part of the completed assembly, the tank, and is not available separately. It is not listed in the Chevrolet Master Parts List.

Re: G506 Fuel Tank Lesson
Yep, I agree. I didn't read the "Neck, Filler" descriptions closely enough. They all indicate "Upper", with some having vent tubes and others not. The SNL list I mentioned above lists a total of 20 unique fuel tanks, and 16 unique filler necks.Ben Dover wrote:My take is that elbow is part of the completed assembly, the tank, and is not available separately.

Re: G506 Fuel Tank Lesson
Can you post an image of the shorter neck? The straight output neck image I posted is from my dumper and the height seems the same as the cargo models.G506 wrote:Hi Paul and all,

Yes I believe you all are correct in the that the tank (cast filler elbow included) is one part number. Why are there parts that carry individual part numbers but are not separated in the parts manual? Do any GMC part numbers begin with "366"?
