Perhaps...
Brew your own - All you need is; A Workbench, 1 pack of Sugar Bombs, 1 Box of Detergent, 2 Maize Cobs & Science Skill 50.
This recipe will produce 20 units (~1 second squirt) of (home-made/crude) Flamer Fuel.
Ergo, you'd need; 500 boxes of Sugar Bombs & Detergent + 1000 Maize Cobs.... to attain your goal of 10k Units of FF (approx 8 minute squirt!).
^ This method maybe useful for subsidising the quantity you are able to purchase from vendors.Considering, Home-made FF is crude, it will degrade your Flamer, faster (3x). In which case, ideally, it is going to be more beneficial to have a companion use HMFF instead of yourself, seeing as weapons are not degraded by them when 'fired'.
Also saving and combining 4 Drained FF Tanks gives 1 Unit of FF.
We get: 1 empty FFT for every 60units of FF used (
I think).
:. 10k units of FF gives an extra ~40 units (2 seconds) when the DFFT are saved and combined.... meagre, yet every little helps!
Keep your eyes pealed for the ingredients and check in with vendors often to acquire the supply you require.why do you want so much flamer fuel in the first place?
Great question. I too am wondering this...
