Bike pump?
I want to fit a bike fuel pump - but the 600 Faser one I've got is knackered.
Can anyone recommend an readily available one that is suitable for a 1660cc x-flow with CBR600 bike carbs?

Might sound a daft question but did you fit it the correct way round.

Do you mean electrically or petrol-wise?!
I think that I was right on both counts... it was pattering with no fuel, and if I'd got the ports wrong it would have just blown bubbles into
the petrol tank...

Not so the bike pump is designed to shut off when the pressure builds up, the weight of the petrol in the tank could stop the pump. If there is no
direction of flow indicated attach a piece of pipe to what you think is the inlet and immerse in a liquid and turn on the pump. If it doesn't
pump the liquid try the pipe on the other end if it still doesnt pump it is probably no good. Bear in mind that the pump is usually gravity fed it may
need to be primed. This is worth trying before you buy another one.

Fair point - I hadn't taken the weight of the petrol in the tank into consideration.
Here's an alternative approach - who can tell me which pipe is which in the picture below?

Have you got a picture of the unit facing fowards, as it may be same as mine.

hi david, it is not the same as mine, put as one can you power it up from a battery and put 2 a hose on each outlet and then put one hose in the jerry
can one with petrol in and the other empty and place one hose in each, and see if it works, mine took a will to start to suck petrol the frist time
but since then it starts getting petrol easy.

I think your right - I need to test it off the car. Trouble is, I hate splashing petrol about the place... it worries me...

did you test the bike pump before fitting it?
i have mine in the engine bay, and it sucks the petrol through.
where is yours?

Mine's in the boot space, just about level with the bottom of the tank.
I have a cunning plan for tonight - use a syringe to put some petrol into each nozzle in turn, then connect up some power to see which one squirts...

hope fully it will work and it was only a mistake of fitting it the wrong way round.
where did you get the pump from?

Fellow forum member, timf.

Sigh...
...I did have it the right way round.
It looks like it pumps OK, but gives up too easily at the slightest back-pressure.
Maybe it just doesn't suit my fuel pipe arrangement - pump at the back near the base of the tank, 8mm copper pipe through to the carbs, flexible
pipe where necessary. About 6 or 7 foot further than it would have to pump on a bike.

at least it is working, have you tried to start the ccar on it, i would have throught i would keep up, or put it at the front so it has least distance
to push.

It wouldn't even fill the fuel filter just before the carbs, so no way was the engine going to start! It barely managed to put 100mls of fuel
into the line.
No - I think I'm back to the original question - can anyone recommend a suitable bike carb for this job? Bearing in mind that I'm not 100%
sure that the fuel feed IS actually the problem? (just 80%)

I recall a while back Mac#1 stocked solid state facet pumps that they fitted to BEC's. Not terribly expensive and obviously brand new for a bit
of piece of mind. Might be worth calling them.
Other than that ive heard people fitting any bike carb pump and getting good results. Mine is from 1000cc bike for ZZR1100 carbs and works a treat. As
long as the pump is working i would have thought anything from a 900 or 1000 bike would do you.

That's what I've got at the moment! It's supposed to be good for 130BHP and I'm not anywhere near there.
If there is a fuel supply problem then it's to do with the pressure regulator - it's a Filter King with the big filter bowl; supposedly
the non-restrictive version.
I think I need to re-wind and find out EXACTLY what my problem is before I spend much more money...

I dont know if this helps, but my set up is fuel tank, pump near tank low down (gravity feed), fuel lines to front of car running low down, through
inline filter (biggest i could get from halfords) then to carbs. No regulator at all. I know i should really have filter before pump as well. Pump is
2nd hand from 1000cc bike.
If i havent started car for a week or so, when i turn key the pump runs for 1 or 2 seconds, slowing all the time until up to pressure then stops. Car
starts no probs (sometimes needs enrichment lever pushing over for a few seconds).
Ages ago i had an issue with the filter blocking, but this was just plastic swarfe from fitting fuel sender finding its way down fuel line - i could
hardly blow through filter but mechanical pump still enabled car to run at normal speeds. I doubt you have this problem - just throwing in ideas.
Sounds like you are just unlucky with the pump and need an ebay bargain to get you up and running.

Just thinking - bike pumps are designed to push fuel (iirc). Some car pumps are designed to pull fuel. Maybe yours needs to be closer to the carbs.
Your comment ref the pump giving up at the slightest pressure build up may be suggesting that it doesnt like a few foot of fuel in front of it.
Could it be easy to rig up temporarily at the front to test the theory.
