In the Kerbal Space Program, players can attach fuel lines to transfer fuel even when using non-cross-feed docks. This can be done by turning off the Resource Transfer Obeys Crossfeed Rules setting in the game's difficulty options. Solid boosters are cheap and efficient at sea level, making them a good choice for adding more delta-v to a rocket. However, it is unclear whether solid fuel can be used in fuel lines as there are no explicit mentions of solid fuel in the fuel line discussion.
Characteristics and Values of Solid Fuel in KSP
| Characteristics | Values |
|---|---|
| Solid Fuel Engines | Used as boosters |
| Monopropellant | Works alone and used in Reaction Control System thrusters |
| Xenon Gas | Used by ion engines and requires electric current |
| Fuel Transfer | Possible between tanks with a heat shield in between by using an external pipe or any part that allows crossfeed |
| Fuel Transfer Buttons | Located by right-clicking on fuel tanks or capsules |

What You'll Learn
Solid boosters are efficient and cheap, but separators are needed
Solid boosters are a great way to add more delta-v to your rocket in Kerbal Space Program. They are cheap and provide efficient thrust at sea level, making them a better choice than asparagus designs. However, there are a few things to keep in mind when using solid boosters.
Firstly, you need to consider the placement of your boosters. If you put them above and below the rocket instead of on the sides, you risk the booster colliding with the rocket during separation unless you use a powerful enough separator. To avoid this issue, you can either add more fuel to your sustainer stage and core booster stage or use separators to ensure a safe distance between the booster and the rocket.
Secondly, you need to ensure that your boosters are correctly attached to the separators. In KSP, parts can only have one parent, and loops are forbidden. This means that you need to use docking ports, struts, or feed lines to attach the boosters to the main body. Struts can add stability without interfering with separators in some conditions, but they can break, so it is important to also use separators between boosters.
Additionally, if you need your boosters to get farther away from your craft after stage separation, you will need to use sepratrons. These small thrust engines help to get rid of empty boosters and ensure they don't collide with your craft.
In conclusion, while solid boosters are efficient and cheap, separators are necessary to ensure the safety and stability of your craft during and after booster separation. By using a combination of docking ports, struts, feed lines, and separators, you can effectively utilize solid boosters in your KSP designs.

Fuel lines can be attached to non-cross-feed docks
In the Kerbal Space Program, fuel lines can be attached to non-cross-feed docks to transfer fuel. This can be done by turning off the "Resource Transfer Obeys Crossfeed Rules" setting in the difficulty options. This setting allows for manual fuel transfer and makes building moon refineries easier.
There are a few things to keep in mind when it comes to fuel lines and fuel transfer in the game. Firstly, fuel lines let fuel flow only in one direction, and decouplers need to have crossfeed activated. Secondly, fuel cannot flow across heat shields, but this can be circumvented by using fuel lines. Additionally, moving tanks or other parts around them in the staging sequence may automatically readjust tank priorities, which can affect the setup.
It is also important to note that fuel flow priorities have been added to the game, allowing for more free fuel flow across the entire ship. Tanks with higher fuel flow priority will be emptied first, and the values outside of the parentheses should be compared to determine the priority.
While the above information pertains to fuel lines and fuel transfer in the Kerbal Space Program, it is not specifically related to the use of solid fuel in fuel lines. Solid boosters, however, are mentioned as a way to increase delta-v and improve thrust in one user comment.

Fuel flow priorities can be adjusted in settings
In Kerbal Space Program (KSP), fuel flow priorities can be adjusted in the settings. This feature was added to the game around a year ago, allowing for more free fuel flow across the entire ship.
To access and adjust these settings, you may first need to activate advanced tweakables. This will make the fuel flow priority settings available. Once activated, you can set the priority for each tank, determining the order in which they will be emptied. Tanks with higher fuel flow priority will be drained first.
It's important to note that flow priority only works between tanks that are directly attached or crossfed through an enabled separator or decoupler. Additionally, separators require specific tech nodes to be researched, such as the one that includes the fuel line part.
When adjusting the priority, it's recommended to use more spread-out numbers for each tank, like 20, 50, and 70, instead of consecutive numbers like 1, 2, and 3. This is because moving parts around in the staging sequence can automatically readjust tank priorities and potentially ruin your setup. Therefore, it's crucial to check the priorities after making any adjustments to the staging.

Decouplers need crossfeed activation
In the Kerbal Space Program, decouplers are essential components that enable the separation of rocket stages. By default, decouplers do not provide automatic crossfeed, which means they isolate fuel consumption within their respective stages. This is important because it prevents the launch stage from draining the payload stage's fuel unintentionally.
However, there are times when enabling crossfeed on decouplers becomes necessary. Crossfeed activation on decouplers allows fuel to pass through them, which can be advantageous in certain scenarios. For example, when using jet engines, enabling crossfeed ensures that fuel can be drawn from every fuel tank within the same "network" or from the last stage with crossfeed-enabled decouplers. This eliminates the need for fuel pipes and simplifies the fuel delivery system.
It's important to note that crossfeed on decouplers does not work with all engine types. For instance, when feeding normal LF-Engines, crossfeed through decouplers is not effective, and fuel pipes are required to establish a proper fuel flow. Additionally, radial decouplers, which attach to the sides of a rocket and eject stages horizontally, do not facilitate fuel flow for rockets. Rockets inherently pull fuel in a straight line, and fuel pipes become necessary to direct fuel flow appropriately.
While crossfeed on decouplers can provide benefits in specific situations, it's crucial to understand the potential challenges it introduces. Enabling crossfeed may impact fuel flow priorities and staging properties, requiring careful configuration to ensure optimal performance. Adjusting the settings related to crossfeed and staging can help address these issues and provide emergency decoupling options or access to additional fuel when needed.

Fuel lines can be used to refuel ships
Additionally, players can use a fuel duct to connect multiple fuel tanks within a rocket or aircraft. This setup enables an engine to be fed by multiple fuel tanks simultaneously, as one tank can be continually refuelled by another. It is important to note that fuel lines only allow fuel to flow in one direction, and fuel cannot flow across heat shields. Therefore, careful planning is required when designing the fuel system for a vessel.
There are also mods available for KSP that provide additional options for refuelling ships. The "KIS" and "KAT" mods, for example, include special fuel lines that can connect two separate crafts to transfer fuel. Similarly, the Kerbal Attachment System mod offers pipes that can be used for fuel transfer. These mods enhance the gameplay experience by providing alternative methods for refuelling vessels.
Furthermore, players should be aware of certain settings that can impact fuel transfer. For instance, the "Resource Transfer Obeys Crossfeed Rules" option in the difficulty settings may need to be turned off to enable fuel transfer in some cases. Additionally, activating "Advanced Tweakables" in the settings can provide more control over fuel flow priorities, allowing players to designate which tanks are emptied first.
