Would the bulb going flat mean the fault is at the tank end of the fuel system (blocked fuel pick up)?

A quick test would be to use a pipe without a bulb. Lift the tank above the engine with the vent open and gravity feed it. If it runs fine your new bulb is dodgy. Some of these aftermarket ones are not very good.

Sceptre Canada make the best tanks, they produce them for Yamaha, quicksilver and Suzuki as OEM. They are more than double the price of a cheap tank but well worth it. Yamaha complete fuel lines are good with the best connectors, stainless crimps etc but as said before the quicksilver primer bulb is very good too.
The tank is also pretty much brand new, has only been used once on a trip and sadly I don't have the money to get a new tank, so will have to stick with this one. I do however have a sceptre bulb and old line laying around that works, but the liner of the fuel line has come away so isn't much good.

Can't under-estimate the issues an aftermarket fuel tank and hose can cause. Yamaha kit is exceptionally well made. Trust me you don't want a collapsing fuel primer bulb on land, never mind at sea. You could get the Yamaha connectors, Quicksliver primer bulb and 3/8" fuel hose and use stainless steel jubilee clips. Would work out slightly cheaper.

I do have a quicksilver tank that I could dig out, however it's fuel of premix fuel so would have to swap that, again! I shall try and get the current set up working before I go about changing fuel between fuel tanks etc

If the fuel bulb is made by Tempo, toss that as well. The one I got for my Honda 40 wouldn't even suck air through a hose.

All sorted! Faulty fuel line, received a replacement today (of better quality as well) from pacermarine which is brilliant! Will be checking the fuel filter and emptying any debris from that and hopefully that should be everything sorted

Ran her up again today, or at least tried to! The new fuel line hasn't changed anything. Cleaned out the fuel filter as well. So I took the airbox off the carbs and found a pool of oily fuel, about 40ml or so that spilled out.. it's evident that it has come out from the front of the bottom carb, not the float bowl, is this a sign of a more serious problem?
