Fuel pressure sensor dodgy connector

I've got a dodgy connector on the fuel pressure sensor. If the engine starts to run a bit rough wobbling the connector instantly sorts it, taking it off and on a couple times makes it fine for a brief while. I've gone at it with a can of contact cleaner which helped for a few months. Now considering a better fix. What are the options? I'm not that keen on £200 buying a new sensor and a new loom, though.
