I sent water to combustion engine with extra utils transfer node, and the water tank fills as expected. I have a lever next to the engine to give redstone signal, but no matter what i try, it won't start. I put lava bucket in the UI slot but it doesn't get consumed. Engine is directly connected to a BC pump. I tried sending lava with Mekanism pipes, from 2 different sides of engine but nothing goes in.

As a workaround i use 4 redstone engines all around the pump. I've tried RF based power generation, like XU lava generator, but the pump is not accepting universal cable from Mekanism.

forge-1.7.10-10.13.0.1188-universal.jar, buildcraft-6.0.17.jar, Mekanism-1.7.10-7.0.0.75.jar, extrautilities-1.1.0f.jar

Lava as heat source for combustion engine was disabled in the past.
