Depends what you wanna do... replace the entire unit and spend hundreds or just replace the pump for £20-30.

You can get just the pump on eBay, any one would do but if any are rated too high (standard is 2.5, I have replaced with 3) then it may or may not cause issues.
I have replaced two so far and on MK3's.

Not to insult anybody but you have to understand how any liquid pump works.
A pump doesn't pump or move fluid, it creates a lower pressure on one side of the pump then the liquid rushes in to equalize that pressure resulting in moving the liquid.
The TMAX uses a one line pump where it has a pressure regulator in the pump like a check valve that only moves fuel only when needed. Sometimes that valve sometimes sticks or gets hung up where it doesn't mean the pump is bad. Also if the fuel line is not tight and "sucking air" that can make you think the fuel pump is bad.
The rule for troubleshooting is a visual, hearing and an understanding how it works.
I understand it's easy to replace parts and you want to replace parts but please take a time out and think about how it works before you replace it.
I believe all that's a matter with it is a simple loose hose connection like you corrected that loose connection when you installed that new pump.
Sorry! those pumps don't go bad, there's always a reason if they did go bad and you must correct that reason.

I'm no expert but I do know there have been problems worldwide with Yamaha fuel pumps. Mainly late mk2's and mk3's
They definitely do go bad..
Mine was replaced free of charge by Yamaha. They've probably had to do hundreds more.
They wouldn't do that if it was just a loose connection.
They did a recall in some countries but not all.
Just google.. Tmax fuel pump and all you'll see is problems.

I mean no disrespect and perhaps some of those fuel pumps are defective.
,,,,,but I have found (at least where I live) that motorcycle mechanics get too lazy to think and are under skilled and they always take the easy road as parts replacers.
The biggest problem today is nobody stops and thinks about how anything works and just guess and replace a part. Too many people think it's normal to replace parts. Before I troubleshoot anything I will stand there in a daze, in the zone and think about it before I dive into it. I troubleshoot electrical problems reading an electrical diagram but have found out too many times that many electrical diagrams are wrong and that will really drive me crazy.
Anytime I am forced to replace any part I will go crazy thinking for a reason why that part failed and how to improve or modify it so it doesn't fail again. You have to know how it works, the science of it, why it was designed and engineered that way, I get inside of an engineer's head and ask myself "Why" why did they design it that way? it drives me crazy!
In my book there's a reason for everything.

I tend to agree with you FatGuy, although in this particular instance there have been many fuel pump failures (they also seemed to be a common complaint on Yamaha Diversions a few years back).
There seems to be a trend these days of fitting new parts rather than repairing the old. Sometimes this is just for convenience or profit but sometimes parts can be made cheaper or more reliable if they are non repairable.
As you say - "there's a reason for everything". All to often that reason seems to be because the accountants said that was how it had to be!!
