Could someone please explain why the fuel pump is so over rated in its output?
The Walbro GS342 is 225lts hr at 5bar when S&S say the engine needs 45lts hr. There’s a lot of fuel being circulated round the system!
I know it probably will be hard to fit but would something like this have more of a suitable output, approximately 100lts hr less.
