Dodgy fuel pump/aftermarket fuel pump?

[gld1400]

Hi all
I had my 14 cut out on me with FI light on going along motorway a few weeks ago, luckily started again and was able able to get home. Today I took the fuel pump out to replace the teabag and the pump assembly itself doesn't look good?
If I could some guidance in this it'd be much appreciated.
1) The top of the black HP filter looks like it's been plastic welded at the top? Is this normal on these filters?
2) The pressure regulator should attach to the HP filter, but on mine it's not attached to anything and is positioned at an angle to the pump assembly? The regulator looks half rusted. The clip holding it on is only half attached too so good job I'm doing this now before it pops off inside the tank (I'd bought some stainless wire to secure the
clip to the assembly as detailed on here).
3) There's a white washer between the HP filter and the pump, I think there's a crack in this washer too...should this washer be here? I don't recall seeing this in the YouTube tutorials I saw.
4) Is this an aftermarket pump fitted? There's big gaps where the pump goes into the base plate, so fuel comes out from the plate.
5) It's been worked on before, the screws have marks on and there's gouges in the plastic towards the top of the assembly.
6) Lastly the fuel line linking the base plate to the tank looks kinked, is this ok as it's I think just the low pressure line?

Can this pump be repaired/saved, is this all ok or is it time to look for a replacement?
The bike was running ok before the cutout, a bit rough in low revs though.

Trying to add photos but they're are all too big to put on the post

Apologies for my long post everyone

Hopefully this works...

Gidday, there are a few threads about the fuel pump in the sticky section at the beginning of the Fuelling section.  Here are a couple that you may find useful.

gld,just a bit tatty prob be ok with reg relocated & new low pressure hose. But id be buying the busa filter assy ebay.Very cheap, comes with reg.Fit pump, tie wire reg job done.

Before we found the Hyabusa filter and hp pump, the Quantum EFI pump was also a good option. I have one in my K3, no issues.

Eric, no pump with filter assy so your option with it would be perfect👍

That all looks perfectly standard & normal except for the pressure relief valve half fallen out, which will have been your problem.

Cheers everyone,
Took the release valve off this eve, cleaned it up a bit. It looks like the electrical connectors for the pump are too big and the bottom of the valve is fouling on them, which is why its seated at an angle and cant fit squarely into the filter, so I'll need to replace the two wires.
Thanks also for info on the Quantums, just found the post here comparing the different fuel pumps.

Update, I'm going to replace the fuel pump, I've got an aftermarket Highflow one with blade terminals for the wires, which nearly fell off when I turned the pump upside down.
Is the Hayabusa pump ok to fit to the GSX with the Busa filter assembly? Looking at the Quantum pump too, it's more expensive though.
Thanks all, apologies for all my questions

I believe the Busa filter is identical except it's got two mounting holes at the top for the fuel level sensor we don't need. I'd assume the pump is the same as it seems to be the same one used across pretty much every FI Suzuki at the time.

Oz ebay today, complete unit $100. Just remove float assy.Obviously chinese but that doesnt really worry me nowadays

I put a Busa one in last year, no problems at all, tied the new regulator in just as a precaution.

Cheers everyone,
Busa filter assembly it is.
Looking at the fuel pumps, has anyone here fitted the Kemso pumps?
They're a lot cheaper than the Quantum ones, made in Japan so should be good quality, rated at 200 lph, and comes with a lot of the parts I'll also need, like the grommets, connectors and I think the low pressure hose.

Thanks again all

Kemso get good reviews.Either made Japan or Texas.

[Eric GSX1400K3]

No, haven't tried those, but a good find.   The quantum is a direct drop in replacement. You get a bunch of different teabags etc and you have to assemble the reg onto it, but otherwise perfect fit
