So I have the hose on the outside of the crankcase that pulls oil from the crankcase, through the oil pressure sensor, to the cams and it's leaking. I bought a new hose, but am wondering - do I need to drain the oil and replace before I put the new hose on?

Do I need to prime the hose in anyway?

Ive got this weird fear that if I put on a new hose I'll starve the cams of oil on startup because the line will be dry

I've got a manual and it only talks about removing the pressure switch and using silicone sealant on the threads when putting the switch back together, I couldn't find anything about the removal of the actual hose
