zx10 fuel pump question
Hi there,
Does anyone have a zx10 fuel pump like this?
 
zx10_fuel_pump_sump_question
I see that the metal cover extends below the mounting ring with the tank. Is this a sort of sump to ensure that the pump always gets fuel?
If so, does that mean it can be mounted on the underside of a horizontal tank without problems.

Thanks Paul,
I had seen those photos, I just wondered whether the sump on the tank is really necessary given that the pump seems to have a decent sump on it
already.
I guess it depends on whether that metal bit on the pump below the tank level is full of fuel or pump.

Hi Matt
from memory it is a bit of a sump but its pretty small and has the pickup etc in there,the mounting on the bottom of my tank is probably 10mm so
combined it should be enough.
whens your SVA?

Dan,
That was what I was thinking, also the design of the filter means that air will tend to fall to the top of it.
I am developing a dislike for carbs, so was thinking about adding EFI to the GSXR1100. It could be a first step to a new engine.
SVA was last Wednesday.
I failed on:
emissions (pre 95, but far too rich, HC 3500, CO 5%)
light directions (out of adjustable range)
brake hose (no documentation)
speedo (separate battery, which isn't allowed now)
noise couldn't be tested as the engine wouldn't start at the end (too much carbon on plugs after idling for an hour)
Where did you get your emissions sorted out? Do you think they might let me play with my mixture screws?
Matt
Not a bad experience.

not too bad all in all then.
for a carb engine maybe a color tune might be a good idea as you've got more relaxed standards.
i used a few mot places but couldn't get it, they let me tweak it at sva but again couldn't get it, gave it a full service, had a mobile
tuner come out and stuck it on his gas tester and a 1% fuel change did it (was 1.04 lambda no 1.03 or under) but everything else emissions wise was
much better, worth giving it a new set of plugs / oil / filter and see what difference it makes.
if your looking at changing to injection etc how much is a early injection blade? cant be much difference in price of a full efi setup vs a full blade
engine?
good luck with the retest!
ps. my new prop should be here by the weekend so will get it fitted and can take you out for a spin, let me know when your free.

My plan is to get the carbs balanced, then give the colourtune a go.
I don't think it should be too difficult to get it to the right values.
The problem with engine changes are that there are loads of things to change, i.e. prop, engine mounts, manifold. I like the idea of injecting my
engine, but it is a back of my mind sort of project (incidentally early blades engine would be a downgrade).
EFI set-up needn't be too expensive. Throttle bodies and airbox £90. Megasquirt or equivalent £200. Plugs and connectors £30. Fuel pump £40.
Obviously a fair bit of buggering about (throttle bodies to head) and a bit more cost if I add a lamba sensor into the mix (another £140 for an
LC-1)
Thanks for the offer of a blast, I look forward to it.
Matt
