looking for some nice fuel tanks, and possibly making one of them a half-diesel, half-hydraulic oil tank.

any ideas who sells this sort of thing? or at least sells aftermarket tanks that i could customize?

 

I know there are some "L" tanks with 2 compartments made by either Weatherguard or Better Built. They're typically used for diesel/gas combos but I don't see why you couldn't use it for diesel/hydraulic. They're 50gal tanks I believe too. So 100 total.
