The time has come to get the fuel transfer problem which arose mid Old Telegraph track 2 years ago. A job left until we got home.
The transfer pump worked if I applied 12v to it direct. For some time the sub tank gauge has read zero regardless of how full it was.
I think the most likely issue is a failed fuel tank float/sender in the subtank, which in turn will not let the computerised sub tank arrangement work. Sub tank light remains lit all the time when ignition is on. (Yes I have tried disconnecting the battery several times).
Of course if the sub tank level sensor proves to be ok there could be an electrical/computer problem. If that is the case the best option seems like getting rid of that little piece of electrickery all together & getting a manual on off switch to operate the transfer pump.
As the sub tank is not registering anything it seems dropping the tank & checking the level sensor is probably the best first option (& hope that it fixes the fuel transfer issue).
Now the question: Mechanic or auto electrician? (Please don't suggest I do it myself - if I was physically able to I would, but I'm not).
