Attach a fuel line from an external fuel tank to a radial mounted engine

[heebejeebes]

So I am struggling with the first part of a rocket I am designing. I want to have a final stage thuster that allows me to maneuver around after I am in orbit. I want to use two Rockomax Mark 55 Radial Mounted engines connected via fuel line to eight (four per engine) Stratus-V Cylindrified Monpropellant Tanks. I can connect the fuel lines from the engine to the tanks no problem, the issue is that the fuel runs from the first point to the second point and I cannot seem to place the starting end of the fuel line on the external tanks. The game just makes the node pass through the tank without being able to connect.

Here's a visual if you didn't quite understand that:

Trying to figure out exactly why you're wanting to connect a Mk-55 to a Monoprop cylinder. The Mk-55 is a bipropellant engine; the Cylinder is a monoprop fuel source. They're incompatible with one another.

You also don't need fuel lines to feel monoprop thrusters, BTW.

Umm...First off the MK 55 engines don't run off monopropellant, you should use the Monopropellant engine, in which case you don't need fuel lines.

To be more exact, you do not need any fuel lines to feed any fuel to a radial engine. To my knowledge, the radial engines are already set up to feed fuel directly from the tank it's attached to.

Ahh so there are different types of fuel! I've been playing about 8 hours so far so.... good to know

In stock there are four types of fuel and five types of fuel tank:

Solid Fuel -> (combined with) solid rocket boosters

Liquid Fuel -> jet engines

Liquid Fuel + Oxidiser -> rocket engines

Monopropellant -> RCS thrusters and O-10 engine

Xenon -> Ion engine

Solid fuel just 'is' integral to a SRB and can't be moved around but can be tweaked out in the VAB/SPH.

Liquid fuel is the same for jets and rockets, but rockets need oxidiser to burn it, whereas jets get that from the (oxygen) atmosphere. The ratio of fuel:oxidiser is 9:11.

Monopropellant is mainly for low-power RCS thrusters used in docking but the O-10 uses (a lot of) it for main thrust too, if you want.

Xenon is a special case for the very high-efficiency but low-thrust Ion engine (see NASA's Dawn mission to Ceres).
