Solution
Perhaps demoting the FOHE to a secondary system, an ancillary instead of a singular, and Flight Critical component. If I was to propose a fix:
Build a new, shorter HE that has a "Y" at either end, allowing the provision of a gate valve that can Divert Fuel AROUND the Cannister to a Flow Only Bypass that supplies the HP directly in Cold Cruise. If the HE is Bench Built and conforms to existing Entry Exit Plumbing, It could be fitted in a scheduled C or D break, for uninterrupted revenue and Plumbing redesign. I'll call my patent Atty. Interested?
