Evening all,
Hopefully it won't be long until I can start plumbing in the fuel system. I'm unsure which fuel pump to use though.
The engine is a 2.0l zetec silvertop, with gsxr 750 TB's, and using Megasquirt.
I was thinking of going down the swirl pot route, but after searching on here, I read somewhere that I could use an in-tank bike fuel pump with an
in-built swirl pot which will greatly reduce the costs.
My question is this, which pump would be best? Is anyone using one and have any pictures of their installation. Also, do they fit into the top or
bottom of the tank?
Best regards and thank you in advance,
Chris
Give one of these a go comes with fuel level sensor built in. It fits in the top of the tank and is on a spring loaded slider so the inbuilt swarlpot sits on the tank bottom

I would say your on the right track with the bike pump, they can be cheaper and easier to install, the bike pump has a internal pressure regulator
inside the pump meaning you can use it with an existing single fuel line setup.
The bottom of a standard tank can also be easily modded to take a bike pump.
(bike pump shown fits from the bottom up into the tank, the metal part you see is a sump or swirl pot if you wish to call it that)
see the picture of one from a GSXR1000

Thanks for the replies. So will a gsxr pump like the one in the picture be powerful enough to run the setup I'm using?
Thanks again,
Chris

Different models of gsxr1000 make different amounts of power, also the specifications in the manuals (i.e. how much fuel they kick out) differ
slightly. http://www.locostbuilders.co.uk/viewthread.php?tid=138775
But given that the 2001 gsxr1000 (i.e. K1) produces 154bhp, which is more than you will get from your blacktop, and all the later models produce more
power still, you should be fine (until you add the turbo).

Hi Matt,
Cheers for the link. So I'd guess that a K8 busa 1300 pump would be sufficient?
Also, are you going to the june monthly meet?
Best regards,
Chris

The industry standard way is a remote swirl pot.
The bike one may not flow the fuel requirement, and also, a bike tank is a lot smaller so will perhaps not have the swirl storage capacity you need.
(remember a bike tilts as it corners, keeping the fluid to centrifugal force at I assume the 'bottom' of the tank most of the time.
Swirl pot can be had for £30 on ebay, and 044 style pumps can be had for £60. Keep you original carb lift pump to feed the swirl pot and your away
The last thing you want is the engine going lean/doing damage, over a £30 swirl pot!!

Yes of course it would only need to flow the injection amount, its just not something we have come accross at M-Tech. If it works then I agree, it is
a very good, easy, cheap solution, but it is not something we would install for a customer, though that is the joy of 'Locosting' I assume
What are the general thoughts on pre-regulation as opposed to post-regulation? I know some OEM car manufacturers (ie as used on the ST170 are now
doing this) but I would imagine if we were talking serious CC injectors and resojably long fuel line, would pressure drop occur before recovery? Or
having a post filter and high flow lines work better, such as I suppose a plenum type resever. That being said you can;t compress a liquid, but it
would be interesting to know if nay seirous research/trials have been done?
Afternoon all,
Does anyone know if the gsxr 750 and 1000 k7 fuel pumps are interchangeable?
Thanks in advance,
Chris
