[Solved] Bio-Ethanol does not work with Liquid Fueled Firebox (Steam Boiler)

[Shabazza]

I'm using the TechWorld2 Modpack for MC 1.6.4 with RailCraft 8.2.0.0 and Forestry 2.3.1.1
and I'm having trouble with my steam boiler.

When I'm pumping BuildCraft fuel into the Liquid Fueled Firebox, the boiler starts heating up and the fuel gauge rises.
But if I use the exact same piping system and try to pump ethanol into the firebox, the gauge does not fill and the boiler does not heat up at all.
It does also not accept ethanol buckets or cans.
Is this a known bug?
Or am I doing something wrong?

Picture shows a simplified example of my actual Bio-Power-Station.

Would be glad if someone could point me in the right direction.

Has boiler completely burned through the fuel yet? It's only going to take a new fluid for fuel once the previous type of fuel is gone. You can't mix fuel types.

If the boiler isn't hot anyway, I'd break and replace first since that's a simple first step in trouble shooting.

I also thought of this. So I rebuild the thing several times.
It's a Fluid Fueled Firebox with a Low Pressure Tank above it. (just to be sure I re-cheched it. ^^) And I'm also not accidently using kinesis pipes instead of fluid pipes. (would not be the first time...)
My big boiler I actually wanted to setup has never seen another fuel than Ethanol.
I also tried Fluiducts from ThermalExpansion and different sides to pump it in. But nothing. It gets not accepted by the firebox.

Normal BuildCraft fuel rafined from oil however does work with the same setup. So the problem must be either Forestry or Railcraft.
Or the problem sits between chair and keyboard... But I'm not aware of doing something wrong here.

The changelogs do not say anything about restrictions in compatibility between those mods.
But I guess if this is a real bug, then other people would already have brought this up, hm?

Any other thoughts?

EDIT:
It works with the Direwolf20 V1.0.18 Modpack.
The only relevant difference is: Direwolf20 V uses RailCraft 8.3.2.0 and TechWorld2 V1.1.2 uses RailCraft 8.2.0.0.
BuildCraft and Forestry versions are identical in both packs.
So it seems something in the older RailCraft version prevents the boiler from accepting Forestry Ethanol. Strange. I'll update RailCraft to 8.4.0.0 and try it again.

EDIT2:
Works like a charm with RailCraft 8.4.0.0.
So I guess it has really been a bug in RailCraft 8.2.0.0.
Only bad thing is, I got ID errors with the new version. So I had to start over with a new world...

Anyway. Solved.
