720 Fuel tank differences
Some fuel tank differences I've noted across three of the several 720s I've owned. According to Nissan FAST parts application, the tanks available vary as to bed length and cab style (as well as fuel type). As mentioned previously, diesel tanks are not internally galvanized because diesel can etch zinc and zinc plugs filters and possibly other nasty stuff. For that reason, when swapping the SD into a gasser truck, it's a good idea to swap the fuel tank too. Problem is, it appears that there are eleven different part Nos. for the diesel fuel tanks.
The tank from "Lela", 1982 720 KC SD for Mercer Island, my first. I did not think to measure the tank:
The "Orting Truck's" 1981 720 Std cab = 13-1/4"H x 32-1/2"L x 14W
The "Bellingham Truck's" 1982 Std cab = 12"H x 41-3/4"L x 14"W
Kicking Nissan FAST for a long time got it to spit up this info. This is (I think) all the fuel tank part Nos. for all the diesel-equipped 720s through the end of the 720 run.

Legend of applicable abbreviations:
Reg = Regular Bed Truck
K/CAB = King Cab
HD/LB = Heavy Duty Long Bed
T = General term for Reg & Long
LONG = Long bed truck
HD/T = General term for HD/LB, HD/W and C&C
Simplified table:
If someone volunteers to type that up or OCR it, I'll include the text version here for the Search feature; I'm too tired tonight to transcribe it.

My '82 SD22 tank seemed to be identical in shape to the '84 4x4 Z24 tank. The only real difference beside the inside lining that I saw was that the drain bolt on the gasoline tank is located towards the rear where the diesel tank drain bolt is located towards the front.
I've posted this picture before, but here it is again for this tank specific thread. The diesel tank is in the front and the gasoline tank is in the rear. The extra piece on the left side of the diesel tank was left installed on the gasoline truck body, so that's why its not shown on the gasoline tank. They interchanged and all bolts lined up with no issues. The only dilemma I ran into was having to weld new nuts onto the diesel tank flange b/c of bolts that broke from being frozen by rust and had to be ground off.
I didn't look for the part numbers and don't have measurements, but can get them if they would be useful.

On the '81 720 SD tank pic above, two of the mounting bolts were already broken off when I got it. I was able to drill them out without drama, didn't even have to helicoil the flange.TruckA wrote: The only dilemma I ran into was having to weld new nuts onto the diesel tank flange b/c of bolts that broke from being frozen by rust and had to be ground off
[as opposed to the entire afternoon yesterday, removing two broken lower shock mounting bolts on my '94 Dodge B350 service van. Weldnuts on the lower control arm, broken 5/16" bolts, and what a mess to clean them up. Took me hours]
I would like to know the overall length of your tank. It looks taller than my '82 tank and longer than my '81 tank.

Makes me wonder about my Maxima that was converted from gas. The previous owner who did the conversion had a complete donor vehicle. He did a nice job with the conversion, but may not have been aware of the fuel tank issue.

This tank is the gasoline tank from a 1984 Nissan 4x4 standard cab.asavage wrote:I would like to know the overall length of your tank. It looks taller than my '82 tank and longer than my '81 tank.
I didn't forget about you, measuring the length and width of the flange that runs around the tank, it is 43"x13". The overall height of the tank is 13".
