92 rb30 fuel return solenoid

[TroutNut]

G'day. I can't seem to find anywhere online that sells the rb30 fuel return solenoid for 92 GQ. I haven't asked Autopro or anything yet, all closed today, and only listings on ebay and the like show me landcruiser solenoids. Some of the genuine stuff is priced ok, but I don't know yet. Might be a few hundred $, like much of their stuff.
Has anyone got any ideas where I could source one new online? It's off the carbi model. Cheers

At the moment the solenoid is stuck wide open, but when the engine revs it doesn't restrict the fuel return flow to increase the carbi pressure. I had the problem of the fuel dropping down below the sight glass before it suddenly refilled, repeat etc. I cleaned the carbi with the spray stuff by squirting it up the fuel bowl line and the needle and seat freed up and it fills more steadily now, but id like to replace any part that I know is stuffed before I run into dramas powering uphill with the trailer on or anything like that. So far ive only tested the petrol system by revving the engine in the driveway, which is a bit different to being under load.
