Forklift tank on Cockshutt?

Okay, so I have a Cocksutt 30 propane, no it's not factory or I'd have a big bank account. Love the tractor, problem is my propane dealer isn't real keen on coming way out int he boonies to fill it on my schedule. So I'm thinking that a forklift tank, a couple actually, is the answer. I just this week paid out #140.00 some bucks for a new lock off too, so I'm not giving up and switching to gas. Question is- what do I need to plumb this for a forklift tank? Currently, IIRC, there is a "wet" line from the tank to the lock off which then goes to the heater and then to the carb. The heater may come first, I forget. I'm thinking I just need the line from tank to lock off. I believe I have standard 1/4 or 3/8" fittings. I just need to know if there's anything special I need to look for or do and a pictoral or website for info would sure help. It's can't be that complex, I think.

Any help gratefully appreciated.

Not a big deal. A wet line, from the motor fuel tank to the vaporizer or tee into the existing wet line.

Neat photo on this steamy day, thanks.

Just remember a #33 Hilo tank is 7.8 gallons and a #43 tank is
10.2 gallons. (Liquid)

I have this set up on my 850 Ford, it has an Impco Model J Vaporizer, the flex hose with the fitting for a common 30lb tank. Coolant circulates through the vaporizer. Same in principle, but different than the factory arrangement. It is not complicated, but I am not sure plumbing wise why. With the Impco J on there, its a simple design, so if modifying the existing, they each must give the same result. A 30lb tank may give me 4-5 hours run time at medium throttle, I could run a 40lb tank, but it would be a pain to heft it up over the loader arms and into the cradle, but size wise it would be ideal. You need 2 tanks, that is for sure, 3 is nice, but 2 can suffice, often take the spare with me to change when I know its going to run out. 11 years of this, LP used to be cheap, only way to save on it is have a nurse or bulk tank and fill your own, when I have the tanks filled, they are almost the same as gasoline.

Okay, I think I understand what I need to do, thanks. Propane is still cheaper than gas. I'd love to have a line off my bulk tanks, I think they are 250's but my supplier isn't crazy about that either.

GO back to '02 -'04 LP was cheap, at the local Agway where I could get the tanks filled it was like $12.00 for a 30 lb tank and like $8.00 for a 20lb. Bulk would have been even less, if you could fill your own. I found an old receipt, some time back, was shocked compared to now, and I forget at the moment but I think a 30lb tank is almost $30, maybe $28 now. If I could afford to set up and buy bulk, I'd have an LP tractor, even if it was not the one I currently have, as I thought it was still less that gasoline. I am fortunate to not have to do a lot of run time, Agway is close by, but if I did have to run more hours, I'd have to find another supplier, where I could get several more tanks, at a better rate, and not worry about running out.

2 things I like about this set up, (used to be 3 when it was cheap) it runs real clean, engine oil lasts for years with the hours I do, ( run 15w-40 rotella it performs well) and I can refill, very quickly, take the spare with me put it if off to the side near where I am working or just secure it on the deck of the rotary cutter, which some will balk at, but when its time to re-fill, very simple process.
