Welcome to the forum! That's great information and not typical of a first time poster. Thank you for that!
I will caution against using heater hose as a long term fix in this application. Heater hose is not designed for an oily environment (internally oily anyway). Also, heater hose is meant to withstand pressure but not necessarily vacuum. Under certain conditions it might be possible for this heater hose to collapse and cause driveabilty issues. Just something to think about if a year or so from now you start having similar issues, at which time you shouldn't rule out this hose just because you recently replaced it.
