I'm not sure where the leak is because when I submerge the hose in water, the fitting doesn't leak. I was hoping to do the fuel lines myself, as I'm invested in tools and materials, but if nothing works, I'll see if I can find a shop to make them for me. I'm waiting to hear back from Evil Energy support before I try another brand. I just pressurized the hoses and recorded my test, see below.

These two are a 1 minute test on each end

This one is just an example of it leaking because is not tight enough.
