CUCV Blazer fuel tank?

[dyeager535]

Were they "stock" with the small tank? Don't have a manual for one handy, but I saw one the other day that obviously had the small tank, and another I saw today also had the small tank.

I thought maybe the first one was a service replacement or something, but then thinking about how operating range, weight loaded, etc., is figured into everything, the military probably wouldn't do that. Seems odd not to use as large a tank as possible...looks odd with the large skidplate and gap between it and the tank!

Well, 'member these are diesel, not gas. I thought gas K5's had 22 and 31, but that was 70's trucks.

Diesel tanks had less capacity in other apps, probably stands to reason in the trucks as well, but these tanks are definitely shallower than my gas 31 gallon tanks. There is a good 2-3" between the skid plate, where my tank rubs.

prolly require different straps and sending units than civilian models also ? i tried to do some research on this awhile back but could not get much info. /forums/images/graemlins/confused.gif /forums/images/graemlins/ignore.gif /forums/images/graemlins/ears.gif /forums/images/graemlins/thinking.gif /forums/images/graemlins/doah.gif

I would figure my CUCV has a 22gal tank.

Me too, just don't see any civilian ones with the small tank to compare to. And if no skid plate, no easy reference.

civi diesels have 31 gallons as option

Thought military tanks were 25-27gallons ?

 

[mcinfantry]

military specs were 27 gallons on a m1009 blazer

I've read numerous things about these tanks, no one seems to know about:
a) the sending units (civilian/military gas/diesel) and if they differ
b) if gas tanks had a galvanized coating that diesels didn't (because they would break down the coating?)

 

[dyeager535]

If military diesel cap. is less than civilian, gotta be a reason, and that would seem to indicate the sender would be different as well. I think the service manual I have for the CUCV's covers all of them, and I know it has part numbers in it, be awhile before I see that thing again.

Still no idea on the coating though.

The GM part number for a CUCV M1009 fuel sending numbewr is - 25004140, I believe it is the same for the civilian version. Military spec only requires vehicles to be able to travel Approx. 300 miles thats probally the reason for the smaller tank. The tank on my truck is galvinized, Very good chance that they are becuase of added corrosion protection. FYI the M1009 has the largest fuel capacity of any of the CUCV series trucks, all the others only have 20 gallon fuel tanks. Hope this helps.
