If the pump noise goes from loud knocking to a softer tap tap it is just priming. A few things for you to check below.
Is it your low fuel light that is blinking ?
Could it be the fuel from aux tank making float bounce ?
What port on main tank is pump outlet hose attached to?
Is the fuel sender on aux tank wired up?
Where are you located mate. I'd be keen to have a look and try work it out for you. I just wanna see how it's setup for my own when time comes to lol
Another question?
Does the pump switch have 3 positions?
Pump on
Main tank gauge
Aux tank gaugeAttachment 38142
Only 2 positions: on / off and a light which can be either on, off or blinking. It's off when the switch is off, it's on or blinking when the switch is on.Quote:

I don't think there's a fuel sensor on aux tank as I don't have a fuel gauge for aux tank.
I'll have to crawl underneath...
@ liftlid that's a duel fuel switch by the look of it, for switching from petrol to gas
It will have 3 positions as you need to run petrol dry before using gas otherwise it will dual fuel and run like a dog
My picture was of a my diesel change over switch, g = gauge(aux tank)Quote:

Assuming that the blinking light is on the switch and not the low fuel light on the dash I wonder if the light starts blinking when the pump has pressure? If so you might find a pressure switch somewhere.Quote:

A standard tank holds 95 lt and you will have about 20 lt left when on empty.
