Well I have my L almost back together again. When replacing the head gaskets before I torqued them down too much. Because of this I would get some antifreeze on the plugs under boost. So now new head gaskets are installed and the rest of the motor will be put together today.

Well my question is, I will be turning up the power and was wondering if the fuel rails will need to be replaced or is the stock setup up to the task. Was thinking that it may be better to replace them for better flow and also have an adjustable fuel pressure regulator. Will be ordering the 255 fuel pumps today and installed this week. My goal is to run 10s next week. Also would going to larger injectors be a good idea?

If replacing the fuel rails is a good idea, where do I purchase them from?

 

Try www.modularperformance.com for the rails and injectors.

 

If you are going to redo that much of the fuel system, why not put in new fuel lines with a cleanable filter?
