so by looking into long range tanks 76 long range tanks will not fit (by my research) because of the fancy compartment located in the floor as shown in this picture.
Sometimes i wish I had the poverty pack version.
Here are some 77 shots
here is a shot explaining why I don't think it can work. Kind of a bummer.

I was just fiddling with the rear fuel tank for my 79 body on and stretched 80 frame. I don't know if it will work for you but what I'm using is for the rear "sub" tank is a fuel tank out of a bj74. It fits back there nicely I just need to fab some brackets.
On the wvo/svo...I've attempted to run it in a 1hz and a 2h. I didn't really like the results. The oil has to be really warm for the engine to run right. I also tried running a blended mix of 50/50 wvo and diesel. They both didn't like that either. I'm no expert at this but I think it has something to do with the indirect injection. I've run it in my Hino cab over which is a direct injection diesel and it runs fine even in cold weather.
There is an old diesel mercedes for sale just up the road for me for cheap. I'm thinking of buying it just to do some experimenting with wvo. Might be a good $500 experiment.
As nice as your rig is be careful not to harm that pristine engine with nasty cooking oil

Same size tank and same tank as all rear stock 70 series.
As for WVO it must be cleaned (heavily filtered) and dewatered and heated up to a minimum of 70 degrees Celsius before hitting your injectors. At this temperature it is the same viscosity of diesel fuel.
I have researched this heavily. At this point I am not going to be doing it on my 77, I don't need the hassle or project in those terms.
Foreal, what are you talking about a heavy filter- and dewatering system in your cruiser? I used used veggie oil in a 4runner and in an Isuzu Bighorn (Trooper), just in my standard tank and with no extra filters. A friend of mine collected the soya oil from restaurants, for nothing, cleaned the stuff, put some additives in it and sold it to me for half the price of normal diesel. And I never had problems with my car.
And he already uses it for years in a Isuzu Trooper, a Ssang Young and a Mercedes 300 series.

yeah good point but the 74 tank came from japan so it wasn't completely rusted out...one of the only reasons i'm using it b/c it looks new and the other one being that it fits.
My problem with the oil was that I never was really driving far enough to get it heated up to the right temp.
If filtered/dewarted properly before putting it in a truck and with the right veggie oil system on the truck I think its a great idea. The home brew methods of a couple 55 gallon drums and a filter don't get it clean enough. Feel free to share the info you found in you research. Always looking for a way to improve my setup.

I don't know how he is doing it precisely. He is some smart inventor and does something with cooking and some biochemical stuff, although it's a quite simple system. But he has patented it and starting to do business with the national oil company here.
Anyway, you absolutely don't need to change anything in your car when you put this stuff in your tank. Like I said, I drove it for approximately a year and it worked fine. The engine even ran a little smoother. Never had problems with it and his Mercedes already drives on it for 6 years without engine problems or growing oil consumption.
The only thing is that your exhaust gasses smell like a snack bar

Its entirely dependant on your oil source. If your source changes it oil often chances are you oil is cleaner.
I would say heavily filter stuff down to about 5 microns with a racor filter to both filter particulate and water.
From what I was reading the highway (fishing trips, and ski hill trips) would be the best time for me to really use WVO or SVO. My daily driving would not permit sufficient heating time for using WVO.
The idea is to have it as clean as possible from your barrel system.
My idea involved using two barrels that are constantly heated by a stick on magnetic heater. I would insulate the barrels a bit for a bit of efficiency. Using a series of felt old clothing filters before pumping oil into the one. The constant heat which will take place over a period of a few weeks will slowly settle out the very very fine particulate that may have missed being filtered from the pre-filter. You can get a series of washable filters that can go down to I believe five or ten microns. The constant heat would evaporate the water and you could pump clean oil from that into a clean drum that could be filtered via a racor and have a ready to pump drum.
I would still install a racor on your truck for that complete system.
I could write a paper on how I would do this but this just about sums it up as quick as possible.

Sounds like he is making bio diesel. This involves cooking the WVO with methanol and a biochemical rxn takes place.
I would love to find an old VW golf or mercedes diesel for my daily driver so I could park the 77 a bit more. A few friends love the older tdi's. Heck my one friend runs a dilution of my waste motor oil 10w/30 in his car and it runs great. I'd be running the stuff if I drove a s*** box like his
I have a quick question for you foreal...how down past the bottom of the frame does the stock tank sit? Or if anybody knows how far down past the frame a stock 79 series sub tank sits. I planning on using a bj74 tank back there but it drops below the frame rail a few inches...i really don't like that but I might have to live with it.
crushers said:
They work different , the 80 has a pull lever and flap to switch between the front and back , the 105 has two fill holes (front tank & back tank) but in the same filler neck
So I presume different part numbers , I have a mate who fitted a 80 filler to his 105 though

are you really going to scrape a fuel tank? i think i am more likely going to drag a bumper.
I don't know the measurements.
thanks for the pictures mate...thats exactly what I wanted to see.
I doubt I will every scrape or get hung up on the rear tank. I just don't like things sticking below the frame.
Plus I won't have leaf springs to block the tank
