Just tested with Imuya-kai and regular Imuya, her resupply is exactly the same. For 4 bars, it's 4 fuel/8 ammo. Non-remodeled Goya and Iku also have that same resupply, and I assume non-remodeled Hachi does as well. 4 bars for Shioi-kai costs 10/12, which matches the fuel resupply of 25/30 we have on this page. Not sure if non-remodeled Shioi's resupply is any different.

In short, any non-remodeled sub except Shioi (and Maruyu) has the same resupply costs as Imuya-kai. And there's no reason not to remodel every Imuya you have when they hit level 50.
