[Main vs. Auxiliary Fuel Tanks - 1973 IH 1210]

Just brought home a ‘73 1210 pickup, and am doing some wiring cleanup to track down a parasitic drain. I don’t have an owners manual (yet), and am wondering which tank is considered the main and which is the aux? I’m ASSuming the one with the filler neck behind the passenger door is the main, and the filler neck behind the right front wheel is the aux - but wanted confirmation before buttoning up this part of the wiring. Thanks in advance.

Stout...Trying not to avoid your direct question, I would emphasize that the I-H trucks of that period were ordered ala carte, each vehicle's Line Set Ticket unique and looking much like an order sheet—because it was.  If you have the original or duplicate Line Ticket for the truck, the document often indicates the shipping weight or FOB weight.  This is very close to actual curb weight.  Line Set Ticket (LST) duplicates are available at:

As a broad guess, I would characterize the curb weight of a 3/4-ton regular cab 4x4 with "8-foot Bonus Bed" at somewhere between 6,200 and 6,800 pounds.  I could be off.  Options would tip the scale. 

I managed to find this spec sheet/ad for the lineup of 1972 I-H pickups.  4x4 ("All-Wheel Drive") is footnoted in fine print as "available".  Specs for a 4x4 are not listed, and the key would be the weight capacity for the live front axle.  Traditionally, if you use the gross vehicle weight range (GVWR) as a yardstick, for a 3/4-ton capacity truck, you subtract 1,500 pounds from that GVWR figure to determine the approximate curb weight.  The base or "Standard" 1210 rates 6,300 pounds, which would put the 2WD base model at 4,800 pounds curb weight with its 2WD beam front axle.  The Optional 7,500 and 8,200 pound GVWR would be more like a 4x4.  Here's the link for some general information on these 1972 models:

Unless this question is about a potential vehicle or project that you have in mind, if you have access to the truck, run it over truck scales at a truck stop.  The scales are very accurate and will provide the front axle weight versus the rear axle weight.  If you plan to actually use the truck, the bed load or a camper needs to match up with the vehicle's axle ratings and the weight distribution front and rear.

If you can get the vehicle to a truck scale, remove all excess items, run the truck low on fuel, and get out of the truck during the weight tally.  When you have firm axle weights and the total (curb weight), please share the details with us.  Let us know the Line Set Ticket features for the truck.  Others can benefit from your findings.

Thanks for the reply. Now that I’ve completed the purchase of the truck, I have the LST. It shows a GVWR of 6,300 lb for the truck, with a front GAWR of 3,000 lb and rear GAWR of 3,400 lb. 

The reason behind my question was that I need to rent a trailer to tow the vehicle from Colorado to Illinois. I can rent a 7,000 lb GVWR trailer (trailer weight ~1,500 lb, so GCWR ~5,500 lb) for $250 a week, or a 10,000 lb GVWR trailer (trailer weight ~2,200 lb / GCWR ~7,800 lb) for $450. I don’t want to throw money away, but it sounds like I should be able to get by with the 7,000 lb GVWR trailer.

i agree that the ideal solution is to drive it to a truck scale, but I couldn’t do so without being in Colorado. Do you see any flaws in my thinking?
