collected motorhome from dealer for other warranty repairs
next day I notice fuel gauge at zero with light flashing.

although there was 1/4 of a tank there on the drive home.

put another £50 in
gauge still the same,
cleaned connections on pump.
discon-recon batteries
to no avail.

model is the X250

looking for any help identifying wiring/relays
or any suggestions welcome.

or it is back to dealer for warranty again which is a PITA and time consuming

reply to own thread but update
pump between front seats
4 pins on pump
2 for pump
2 for level gauge

level gauge pins should read 20ohms to 300ohms
mine had none

back to dealer
they removed pump and found level gauge pcb corroded requiring replacment

the flashing yellow light signifies faulty wiring
turns out mine was wiring inside tank in way of PCB corrosion
