What You'll Learn
Asparagus staging
Fuel lines are used in Kerbal Space Program to run fuel from tanks to engines. Asparagus staging is a rocket design method that involves using parallel engines and fuel crossfeeds to increase initial thrust and available fuel while reducing the dry mass of later stages. It is properly known as a propellant crossfeed system and has not yet appeared in real-world rockets, although it has been proposed multiple times. Asparagus staging was a very effective method of building efficient rockets in early versions of Kerbal Space Program, although several updates have since made it less effective by making the drag model of the game more realistic. It is now usually better to use a single large main engine per stage and a less complex arrangement of boosters. However, Asparagus staging can still give a good profit on fuel over a couple of stages, enough to give you that extra Delta-V to get past the atmosphere or perform those costly orbital manoeuvres.

Fuel lines and symmetry
Fuel lines in Kerbal Space Program can be run using symmetry to make the process easier. One user recommends using 2-way symmetry for placing each pair for asparagus staging, which makes it easier to run the fuel lines and reduces the chance of glitches. However, another user encountered a problem with fuel lines not functioning properly when using symmetry, with fuel draining from the wrong tanks. This issue was resolved by removing all the tanks, lines, and engines and then redoing them.

Fuel lines and glitches
Fuel lines are used in the Kerbal Space Program to run fuel from tanks to engines. However, there are some glitches that can occur with fuel lines. For example, fuel lines can sometimes glitch out by mixing symmetry with non-symmetry. This can cause the fuel to drain from the wrong tanks, leading to the spacecraft tumbling due to weight and balance. To avoid this, some players recommend using 2-way symmetry when placing each pair for asparagus staging, as this can make it easier to run the fuel lines and reduce the chance of glitches.

Fuel lines and weight
Fuel lines are used for asparagus staging, a rocket design method that involves using parallel engines and fuel crossfeeds to increase initial thrust and available fuel while reducing the dry mass of later stages. Asparagus staging allows you to pump fuel from the tanks of your external boosters into the core stage, so that when you jettison the boosters, your core tanks are still full. This method was very effective in building efficient rockets in early versions of Kerbal Space Program, but in modern versions, it is usually better to use a single large main engine per stage and a less complex arrangement of boosters.
Asparagus staging can add weight to the rocket, so you need to add engines to the tanks. This results in boosters that boost your main stage, but after they are jettisoned, your main stage is still full of fuel. You can achieve this by making the yellow fuel lines go from the boosters to the main stage, making the fuel pump automatically (ensuring the arrows on the pipe are pointing towards the main stage).

Fuel lines and engines
Fuel lines are used to connect fuel tanks to engines in the Kerbal Space Program. They are an essential component of any spacecraft, ensuring that fuel can be delivered to the engines for propulsion.
When designing a spacecraft, it is important to consider the placement of fuel lines carefully. One common approach is to use two-way symmetry when placing fuel tanks and engines. This allows for easier routing of fuel lines and reduces the chances of glitches occurring due to mixing symmetry with non-symmetry.
However, there have been reports of issues with fuel lines not functioning properly, even when using two-way symmetry. In some cases, fuel keeps draining from the wrong tanks, causing the spacecraft to tumble due to weight and balance issues. It is recommended to check the direction of the arrows in the fuel lines to ensure they are facing the correct way.
To troubleshoot fuel line issues, it may be necessary to remove and redo the fuel lines, tanks, and engines. It is also important to ensure that there are no modded parts or other modifications that could be causing the problem.
