The tell-tale on our BF50 has always been a PITA. The outlet spigot has an ID of approx 2mm, the rubber tube from the block fitting to the spigot has an ID of 4mm. This restriction meant that any tiny bits of crap that came through would block the spigot.
Anyway, the rubber tube has stretched slightly and last night it popped off and flooded the pan.
Much washing, flushing and spraying of WDF followed.
I've now fitted a longer rubber tube which hangs out of the bottom of the pan by 50mm and fitted cable ties either side to keep it there and dumped the restricting spigot.
My question being, is the greatly increased tell-tale flow likely to hinder the motor in reaching correct operating temp?
